tps and OS sensor dicussion.first of all, in either case you would have and engine light come on detecting sensor failure by your computer. In the case of and o2 sensor, you will notice gas mileage decreasing and in certain cases hesitation during acceleration. If you have a miss on initial start cold it will not be related to your o2 sensor, since there is no reading until a specified heat range in your engine. Using a good scanner should determine what bank, either bank one or two sensors are creating the problem. As far as tps is concerned, you will probably have a serging in your rpms. It will drop and increase for no reason. All it is is a potentiometer in sort that controls the position of your butterfly at the throttle body. Hope i was able to help.. Nelson

it can cause the car not to start.

It is a part of the throttle body. You have to replace the throttle body if faulty.

The throttle position sensor determines the amount of throttle used when the engine is running at various speeds. If the sensor is faulty, it can be replaced by ordering a new part.

faulty throttle position sensor?

PO122 indicates the throttle position sensor (TPS) is faulty

Misfire is usually caused by faulty wires or spark plugs or both. Throttle position sensor failure generally causes poor response to the throttle. That is poor acceleration, slow to return to idle and rough idle.

I had a similar problem with a Toyota where it was sending the code for Throttle Position Senser I replaced it twice It ended up being the computer that was faulty [[Hope this will help

There are a few reasons. crankshaft position sensor, faulty fuel pump, fuel pump regulator, throttle position sensor, oxygen sensor. Need to have it diagnosed.

Yes, my grand am had that problem a week ago, changed out the sensor and it runs like a champ!

The possibilities can be many. It can range from a malfunctuioning fuel pump, to a bad throttle position sensor, to faulty fuel injectors. First I would check the throttle position sensor since this is the cheapest part, and also the easiest to replace. The throttle position sensor tells the computer how much air and fuel to put in the engine. If it is messed up it can cause hesitation, stalling, transmission buckoing, etc...

The bad idling may be due to a faulty Throttle Position Sensor (TPS). Have the computer scanned for trouble codes to confirm before replacing.

AnswerBY CHANGEING IT OR SIMPLY GOING FOR A DIAGNOSISThere are several position sensors (crankshaft, camshaft, throttle, EGR). Any one of them would illuminate the "Check Engine" light and the code(s) would lead you to the faulty one.

because the throttle linkage is suck or the carburetor is faulty

User Avatar

Check the wires to the maf. it is between the air filter and the throttle body, if it is disconnected or faulty in some way what you are describing will happen

User Avatar

well if the throttle isn't getting gas to the engine it would suddenly stop because of no fuel. On the other hand if the faulty throttle is like some of the Toyotas lately and gets stuck to the floor, your car would suddenly work way too well! :o

User Avatar

I'd suspect a loose, damaged or unhooked vacuum hose/line around the upper/lower intake. Or a faulty throttle position sensor.

Hesitation can be caused by several things: 1. A faulty throttle position sensor might cause hesitation. 2. A faulty MAP or MAF sensor might also cause hesitation. 3. A problem with the engine control module might cause hesitation.

User Avatar

Sputtering engine may be caused by one or more faulty components. It may be from spark plugs, spark plug wires, distributor cap and rotor. Similar faulty component affecting the air-fuel mixture like a bad oxygen sensor, throttle position sensor or engine temperature sensor.

User Avatar

The mixture is electronically controlled by the computer via a throttle position sensor (TPS) tha is mounted somewhere near the carburetor throat. The sensor may be faulty and needs to be replaced.
