Hi everyone,
I have a problem with two fault codes in my PEUGEOT 307 1,6 HDI 2007.
P0121 and P1531, P0121 need to be resolved in 1 month or I am not permitted to use the car.
Fault codes:
P0121 - Throttle Position Sensor/Switch A Circuit Range/Performance Problem
P1531 - Invalid test - Accelerator pedal movement
If I have found the correct meaning for the fault codes.
I guess that these two codes are connected, my guess is that the position sensor from the throttle(s) are giving a value that does not agree with the data map.
I did reset the codes with an OBD-2 instrument. Did not use the car for a few hours and then after I had used it later that day P0121 was back.
I did reset it directly when I came back and went for a ride when the engine still was hot and the code has not come back again.
So it is hard to know what is triggering the fault code.
What I believe is a throttle:
Delphi No. 9657485480 or 25378171REV
It looks like it has two throttle actuators, one that can bypass the intercooler (used for cold starts maybe?) and another one that is located after the intercooler.
Anyone that has any experience from this fault code on a Peugeot 307?
I'm thinking of buying PRF 7-78 contact spray and just use it on the contact I believe is for throttle control, or is it just a waste of money?
If someone suggest using oscilloscope on the contacts for the throttle, if someone has a schematic for the contact would be awesome
Sincerely,
Rubb
