Hello
For a long time, I have a problem in my Peugeot with the antipollution fault message appearing from time to time and the engine light coming on.
After connecting to a simple elm327 tester in the Scan master elm program, the elm reads the error code p0121 the potentiometer circuit of the switch A incorrect range of the throttle or gas pedal signal.
I bought a different throttle - the problem returned.
I replaced the second throttle - also used, but checked and functional, and the problem still came back.
The voltage on the fifth pin of the throttle plug is correct even when the car is in emergency 5V mode.
The 5V voltage on the potentiometer is also correct.
I have recently noticed that when the error appears and the car goes into emergency mode, it is enough to unplug and re-plug the throttle cube and after driving a few kilometers the error automatically disappears.
but after driving about 100km, the error returns.
The throttle cube itself seems to grip tightly on the throttle joint - there is no play.
I also checked the continuity of the wires with a meter from the throttle cube to the controller cube and they are all ok.
I also removed the damper itself and took off the plastic cover to get inside. There, the damper connector with the plate is connected by aluminum wires - but also there all connections are fine.
What could cause this error to appear?
I also note that if the engine light comes on and the above error appears, then the car has no power at all. You can push the gas pedal to the top and the revolutions will increase to a maximum of 2,000. and at idle, either the car goes out or has increased speed (up to 1400)
This error occurs only on a cold engine running on gasoline. (the car has bezyne plus lpg)
