peugeot ecu problems

[daewo97]

I have a peugeot,407, hdi 2 liters, code rhz engine, ecu code D9C7C,ECU does not recognize the accelerator pedal sensor,I opened the ECU, and I checked all connections,but the pin 20 from socket ecu not communicate with any part of the ECU.Please, if anybody knows who communicate this pin 20?, what transistor or resistance from ECU,I checked all the soldering of the ECU, and neither communicate with pin 20. THANKS!!

Check on autodata pin description.

I ,do not find from the transistor or resistor, the circuit to pin 20.inside the ECU

Maiby its not used my friend,first see where this wire go,take a schematic don t measure inside ecu untill you don t know what prupose have that pin.

please excuse me, I received the wrong information, it is a peugeot 406, engine code rhz, one with a single plug and the pin 22 is broken, it does not communicate with any transistor or resistor on the ecu

First cheq the wiring map and route, generally a TPS fails by lost a 5 Volts from ECM, cheq 5Volts and ground.

pin 22 is app sensor, common for part on the pedal to go down on these.
