A TPS is a variable resistor that tells the engine computer the absolute throttle opening percentage. A switch tells the system when the throttle is wide open for enrichment purposes.
The TPS (throttle position switch) is attached directly accross from where the throttle cable attaches to the throttle body. It is held on with 2 torx type screws.
P0121 - Throttle Pedal Sensor Switch "A" Circuit Range/Performance. Most common fix is to replace the Throttle position sensor.
I had the same problem, so I changed the throttle position sensor and the camshaft sensor as well...it worked for me, hope it works for you too. also change the map sensor that was the reason the light was on
My friend is having the same problem. After some research, I've come down to it being related to the idle switch on the pedal assembly. The switch is there because your throttle is electronically controlled and the switch is a canceller. If you release the throttle but the throttle position sensor is messed up and saying that there is a throttle input the truck will try to keep revving. So the idle switch cancels any signal that is being put out by the throttle position sensor. If the Idle switch sticks, it will cancel out your input into the throttle pedal. So when you want to go, the idle switch thinks that your still in idle mode. In a nut shell, people are saying that you need to replace the throttle pedal assembly. It's relatively easy, kind of expensive though. About $220.
No, I cannot show a picture.
Trouble code P2125 means: Throttle/Pedal Position Sensor/Switch ""E"" Circuit I would replace the throttle position sensor
hi i have a clio 1.2 2001 and have a fault code p0225 throttle/ pedal position sensor switch c circuit. i have changed the throttle pedel and has made no diffrence the vehicle still wont rev up but cant find the throttle position sensor under the bonnet please can you tell me were it is located. thank you.
The throttle position sensor is on the throttle body. That's the part of the engine that controls the amount of air allowed into the engine. To find the throttle body, follow the air intake routing toward the engine. The throttle body is the part that sits on the intake manifold. To find the throttle position sensor, follow the throttle cable to the throttle body. If it helps, have someone press down and release the throttle pedal while you're looking for the throttle body/position sensor. The throttle cable causes a shaft to turn, that's the part that controls the air coming into the engine. The throttle position sensor is connected to that shaft.
I read somewhere on the internet that there was a defect with the ingnition switch due to a recall and what they were doing was installing a relay switch. i dont know if that is it but that is what i read and heard.
Not to my knowledge.
To repair the P0120 code you need replace the Throttle Position Sensor/Switch. You will find it located on the throttle body of the intake manifold in the engine compartment of your vehicle.
Remove the engine shroud and locate your air intake on the left hand (passenger) side of the engine. Follow the intake to the point that it connects to the throttle body. Directly behind this connection between the throttle body and the firewall you will find the throttle position sensor. The electrical clip has a housing on it that needs to be removed before you can remove the switch. Remove the engine shroud and locate your air intake on the left hand (passenger) side of the engine.

Basically, these throttle performance switches change the value that your throttle position sensor gives the ECU. This, in effect, leads your car's computer to believe that it is reaching wide open throttle sooner. How can you do this without buying a throttle performance switch? Just put your foot to the floor faster! No matter what the manufacturer might claim, your car won't make any more power than it did before you installed the switch, you'll just feel it sooner.
It is a possibility.
The switch is to limit the engine RPM if the throttle sticks wide open.
It is to the left and slightly down of your throttle body. Follow your air filter box all the way to the throttle body and to the left of that on the block is the sensor you can not miss it their is wire clipped on top of it. If you unclasp that wire you will see three prongs and that is your sensor/switch. Very easy to replace.
code 51 is a switch condition signal diagnosis no IDL signal or A/C signal to the ecm when the test connector E1 and TE1 are connected probable cause A/C switch or circuit A/C amplifier neutral start switch (A/T) throttle position sensor throttle position sensor circuit to fix i am not sure what one is wrong but i gave you what it is by my code book
Yes. It's designed to prevent cranking while the vehicle is in gear.
Electronic choke. It is the air temp sensor just upstream of the air box sending info to the throttle body in conjunction with the antifreeze temp sensor, located on the rear of the block near the firewall, telling the throttle body to increase fuel via a vacuum switch beside the throttle cable on the front side of the throttle body. I think. Maybe. Who knows.
Under the hood, find the area where the accelerator and transmission cables meet on the circular device near the intake. On the other side of that device should be the throttle position sensor.
Throttle position or pedal position sensor/switch circuit, low input
Trouble code P2122 means: Throttle/pedal position sensor/switch "D" circuit low input
Your throttle valve switch (position sensor) is bad and need to be replaced.....this is located on the side of the throttle chamber. You can get this from Advance Auto for $60 and is easy to replace...
On the cars I've worked on, you don't have to adjust anything. Sometimes you have to rotate the actual TPS and then screw it in once it's resistance is where it should be... but I don't see why you would have to do anything to the throttle body itself.
