peugeot 307 1.4 16v on a 04 car will not rev engine light on and coming up with a code of p0121 throttle postion sensor replaced the sensor witch is part of the pedal still the same please help
This code is relevant to the throttle body on the engine and it requires a new throttle body.The throttle body has a sensor built in to it which monitors the flap position and adjusts it accordingly to the pedal position.
hi is there any tests i can do on the throttle body to make sure its that
Only if you have the correct diagnostic tools and software to tell you the measured points, a visual check will not help.
i have the snap on ethos diagnostic tool just not sure on the readings i should be getting anymore info will be a great help otherwise might have to try a second hand one
With the main dealer diagnostic kit you can compare position readings of the throttle body/pedal.
I have no experience of the snap-on system
Best to try a new unit
