The TPS is usually held in place by a couple of fasteners and one or two wire connectors that can only be put one one way. You should not have any problem replacing it.

Why 2.5l ford ranger engine revving up on its own?

my guess is the throttle position sensor it on the top of the intake manifold 2 bolts hold it one

You own a Toyota Camry that has a choking down sound when at a complete stop but never chokes down?

Try cleaning the throttle body (you can get throttle body cleaner in virtually any auto parts store), looks like you have problems with idle control valve to throttle position sensor. Both of them are located at the throttle body.

Where is the throttle position sensor located on a Oldsmobile silhouette?

Hi all, I own one so I know where it is. Follow the four inch air hose leading from the air filter back toward the engine. Looking at the van from the front the filter is on the drivers side. Just above the manifold you will see where the throttle cables attach to a cam like item. Look behind the throttle body and you will see a sensor like device with four wires. Just under that sensor you will see another sensor with connector that has yellow rubber seal. That sensor will have three wires. That is your throttle prositon sensor. Good luck.

Where is the throttle position sensor located?

With the engine off, have a friend press down on the accelerator pedal and let it up a few times while you watch under the hood.You'll typically need to remove some of the air filter and intake hoses to watch the throttle cable function, but note where the throttle opens and closes as your friend presses on the pedal.The shaft that goes through the butterfly AND THE BUTTERFLY valve are called the throttle. The sensor will be connected to one end of that shaft or the other, and there will be a wire that leads to the computer. All vehicle manufacturers have their own way of doing things, you have to figure out what's going on in YOUR vehicle.The throttle position sensor is usually located on the end of the throttle shaft on the opposite side of the throttle cable.

Why would your Audi A4 increase acceleration on its own?

several things could cause it. a sticking throttle cable (if its not a drive by wire system/available after 01) a stuck injector a stuck throttle body or possibly a short in the cruise control system mine kept increasing speed on it's own and it was the temperature sensor telling the computer that the car was still running cold so the computer was putting more fuel to the engine,nz$250 to replace sensor now running perfect

What is trouble code p1120 - p0120 and the Throttle Position Sensor - TPS - Windstar?

The trouble code #P1120 means:Throttle motor position sensor 1-Circuit malfunction Major auto parts chain told me my TSP (Throttle position sensor) was bad due to the Check Engine Llight (CEL) being lit up - a P1120 DTC.$40 and 10 minutes to replace - ((_#*&$ light came right back. A few days ago, after doing some more reading & investigating of my own, I bought a $4 can of throttle body spray cleaner - used 1/2 the can on my 98 Sable - voila! CEL is gone again! Since this sensor is located at the top of the engine, it is very likely you will be able to replace it yourself.Ask at auto parts store to see a diagram of the part's location. The throttle position sensor, TPS, is mounted on the front of the throttle body with 2 screws, and has a 3 wire connector going into it.The throttle body is the metal unit the air filter housing connects to on the left-side, and also has the gas pedal cables going into it.Simply disconnect the wire harness, remove the 2 screws (tighten a bit before unscrewing to break them loose) - reverse steps to install.Note that has detailed testing procedures that appear easy enough to confirm if the TPS requires replacement. See "Related Links" below. It is attached with 2 screws to the front of the throttle-body - top side of the engine. Rather small with a 2 wire connector going to it.Easiest part to access where the air duct attaches to the throttle body. I believe the voltage is supposed to be 0.5 closed and 5.0 open once that is obtained use a OBD scan tool to clear the code or disconnect the battery long enough to reset it however if you disconnect the battery it will take 40 to 100 miles of travel on the road to pick up all the sensors again and this can sometimes be a head ache TPS IS THROTTLE POSITION SENSOR

Why would a car hesitate when at a stop?

If your car hesitates when the brakes are applied, and or when you are driving it acts like it is giving itself gas, or accelarating on its own, The problem is your Throttle Position Sensor(TPS). It costs about $34.00 at autozone, and only takes about 10minutes to replace. sounds like you need a tune up. could possible be fuel filter or fuel pump. sounds like you need to replace fuel filter, air cleaner, and maybe a tune up

Why does 2000 Impala accelerate on its own?

I have been chasing this problem for a while now on my dad's 04 impala with the 3.4. So far I have learned of three things that can cause this problem. 1- IAC or idle air control valve 2- TPS or throttle position sensor 3- IAT or intake air temp sensor Maybe this will help you out when I finally figure this one out I will try to post again.

Why would your 1999 Grand AM GT Accelerate by itself I have to turn my car off in order to get it to stop doing it. I first thought it was because my cruise control is bad but now it does it randomly?

A bad throttle position sensor could cause a 1999 Pontiac Grand Am GT to accelerate on its own. Another possibility is a loose connection at the idle air valve.

How do you fix hesitation in a 1998 2 point 2 liter Sunfire when no error codes show in on board computer and have replaced plugs wires coil pack and crank position sensor?

If the injector is running a lean you could experience a little hesitation. Most GM vehicles use throttle body injection and only have one injector. If it's gummed up you could get better performance by running a good injector cleaner with the next tank of fuel. If the O2 sensor is faulty you could be running a little lean. If the O2 sensor is over about 50k Mi, replace it. I asked the question, and fixed the problem myself, so am posting the fix for others. It turned out to be simple. It was the Throttle Position Sensor (TPS). It is on the throttle body and is attached by 2 bolts. There is also a wire connector. The whole thing is not much bigger round than a Silver dollar. New one was expensive, so picked up a used one for 20 bucks. Put it on myself in like 2 minutes. Runs like new now. Although the dealer had me agreeing to put on many things (sensors) before I took matters into my own hands. Wish I had done that first.

How do you change the camshaft position sensor in a '93 Pontiac Bonneville SE?

I have a 92 Bonneville thet needs a crank sensor how do you change it Crank sensor is on the pulley and the teeth on the pulley sits inside of it for a megnetic response for computer. It is held on by two small bolts. I changed my own on my 3.8L and my car doesnt want to shift correctly. You are able to adjust and its very picky where the correct position is.

1992 Nissan 240sx tps voltage settings?

Not my work here so ... * Checking the TPS and Adjusting the Idle TPS Testing and Adjustment The TPS is there to tell the ECU how hard you have your foot on the gas. It isn't there to adjust for the idle. It's a sensor. It does have some adjustment of it's own and we'll try to give our version of what our Factory Manual says (though we won't even come close to doing it justice): Throttle Sensor & Soft/Hard Idle Switch The Throttle Sensor responds to the accelerator pedal movement. This sensor is a kind of potentiometer which transforms the Throttle Valve position into output voltage, and emits the voltage signal to the ECU. In addition, the sensor detects the opening and closing speed of the Throttle Valve and feeds the voltage signal to the ECU. Idle position of the Throttle Valve is determined by the ECU receiving the signal from the Throttle Sensor. This system is called "Soft Idle Switch" and controls engine operation such as fuel cut. On the other hand, "Hard Idle Switch", which is built into the Throttle Sensor unit on the A/T equipped models, is not used for engine control. Trouble Diagnoses:1. Disconnect Throttle Sensor harness connector.2. Make sure that resistance between terminal #1 and #2 changes when opening the Throttle Valve manually.Looking at the "pins" of the connector w/ the locking tab of the connector pointing up, terminals #1 is the one on the LEFT. #2 is in the MIDDLE and #3 is on the RIGHT. The results of the test should be: Accelerator Pedal Condition Resistance in k OhmsCompletely released Approx. 2Partially released 2 -10Completely depressed Approx. 10If test shows "No Good", replace Throttle Sensor. Adjustment: If Throttle Sensor is replaced or removed, it is necessary to install in proper position, by following the procedures shown below: 1. Install Throttle Sensor body in the Throttle Chamber. Do not tighten bolts. Leave bolts loose.2. Connect Throttle Sensor harness connector.3. Start engine and warm up sufficiently.4. Measure output voltage of Throttle Sensor using voltmeter.5. Adjust by rotating Throttle Sensor body so that the output voltage is 0.45 - 0.55 volts.6. Tighten mounting bolts.7. Disconnect Throttle Sensor harness for a few seconds and then reconnect it. With the locking tab of the connector pointing up and looking at the back of the connector as the wires from the wire harness go into it, terminal #1 is the one on the LEFT. #2 is in the MIDDLE and #3 is on the RIGHT. Output voltage is measured across terminals #2 and #3 from the harness side of the connector. A&W Question: Do you know the procedure for checking out the TPS and adjusting the idle? Answer:For the full blown check, it has a few steps involving the ECU and it's connections to the TPS. We're going to skip those, assuming they aren't a factor. Also, trying to describe which terminal on the ECU harness to check would be a nightmare w/o a diagram. This is hard enough as it is! Checking for the correct voltage, ground circuit, and resistance are not that tough. So here ya' go... POWER SUPPLY: Disconnect the TPS harness and look at the terminal side of the connector. (this is the side with the terminal connectors in it) With the locking tab pointing UP, the terminals are A, B, and C, from left to right. (Confusing, huh?) This is measured from the male half of the connection that goes to the engine. Turn the ignition ON and measure the voltage between terminal C and ground. It should be approx. 5v. GROUND CIRCUIT: Ignition OFF. Check for continuity between terminal A and ground. Continuity should exist. RESISTANCE: Make sure that resistance between terminal A and B of the connector half (female) that goes to the TPS changes when opening the Throttle Valve manually. The results of the test should be: Accelerator Pedal Condition Resistance in k Ohms Completely released Approx. 2Partially released 2 -10Completely depressed Approx. 10If test shows "No Good", replace Throttle Sensor. VOLTAGE ADJUSTMENT: 1. Loosen the 2- bolts that hold the TPS.2. Start engine and warm up sufficiently.3. Measure output voltage of Throttle Sensor using voltmeter.4. Adjust by rotating Throttle Sensor body so that the output voltage is 0.45 - 0.55 volts.5. Tighten mounting bolts.6. Disconnect Throttle Sensor harness for a few seconds and then reconnect it. Note: With the locking tab of the connector pointing up and looking at the back of the female connector as the wires go into it, terminal #1 is the one on the LEFT. #2 is in the MIDDLE and #3 is on the RIGHT. Output voltage is measured across terminals #2 and #3 from the harness side of the connector. Adjusting the idle is pretty straight forward: Disconnect the TPS harness and turn the idle adj. screw on the IAA to get the car to idle at 650 rpm. Reconnect the TPS harness and your beloved should purr at 700 or so rpm. (The Factory manual gives a +/- tolerance of 50 rpm.) The IAA is at the back of the intake manifold. You can see it standing over the right (passenger side for N.A.) fender and looking at the funky device with the dime size recess for the adj. screw.

Why does my cadillac catera 99 revs up but doesnt go then stumbles and kicks when driving more than 30 min?

May be the throttle position sensor(TPS). I'mhaving the same trouble with mine. I kno in past cases, with different vehicles I've own, that when it revs high and stumbles or sputters it's usually the TPS. It's like $35 from Advance Auto.

The instructions to replace a Honda CR-V ABS wheel sensor is available in the service manual. If you do not own a manual, it can be obtained from Honda upon request.

Why does my Toyota Echo have rough idle with air conditioner on?

Check the basics first (air filter, belts, plugs) but the most likely cause is dirty throttle body or mass airflow sensor. You can easily clean both on your own although MAF sensor should be replaced after 100,000 miles. Throttle body can be cleaned with Seafoam penetrating lubricant and a toothbrush or wire brush. You may also want to test the alternator (Toyota calls it the generator)

How do you replace 02 sensor on my 2001 Honda prelude?

See related links for a DIY, but if you decide to replace this on your own, I would suggest replacing both O2 sensors, not just one of them. They are located on either side of the catalytic converter.

Why does your 7.3l stop on its own?

if you mean why does the engine stop on its own, you probably need to replace the cam positioning sensor on the engine this is an easy job and the sensor is located above the harmonic balance pulley wheel on the front of the engine block this is easiest reached from underneath the vehicle and will take all of 5 minutes to change out
