    Hello,

    My car is Renault Trafic 2.5DCi (G9U 730) 2006. The car crashed at 1,100 rpm and does not react when the accelerator pedal is pressed. To the best of my ability, I measured the resistance when the pedal was fully depressed and in the rest position (the values and instructions from the AutoData program) were abnormal and quite a lot so I ordered a new pedal for replacement - unfortunately it did not change anything. Please, suggest what else you can do about it before a trip to the service / electrician. Below I add a screen with a description of the error from the DDT2000 program. Unfortunately I do not know French, but according to translator means something like "Pedal sensor, track 2".

    Hello. Check with a meter what voltage comes from the engine controller to the gas pedal should be 5V.

    Thanks for the answer, I measured 5.14V - 5.16V so shows my multimeter. I will add that regardless of whether the pedal is connected, the car behaves the same - 1100 rpm.
    PS: unfortunately I couldn't find anywhere on which pin to measure, so I measured them all. 5.14V output on 3 pins (green wire)

    There are 6 wires to the pedal?

    Yes, 6 wires. I can also take a picture of the ankle or give the pedal mark if it helps

    No, you have a problem with the connection between the controller and the pedal. The plug has the markings from 1 to 6 and so after ignition on pins 4 and 5 you should have a voltage of 5V because you have two resistors there. The equivalent of these wires on the controller are pin E1 and H2 in the first connector cube .Check again how it looks on the pedal and if this value is not disconnect from the controller, disconnect the first plug from the controller, see which cables to fasten back and puncturing the wires next to the controller, check if the correct voltage comes out. If there is incompatibility, then you have the controller released voltage will be a problem such as broken wires.

    I checked the tension on the ankle pedal once more, they look like this:
    Quote:

    pin1 - 0V
    pin2 - 0V
    pin3 - 0V
    pin4 - 5.14V
    pin5 - 0.05V
    pin6 - 0.01V


    Yes, but earlier I was wrong with this 3 pin ;)

    With these connectors at the driver, unfortunately I could not measure both of them through tight access, I was able to measure only one - H2 and 1.12V.

    So it looks like chip damage in the engine controller, rudder to be replaced.

    Hello.
    And how did you end up with the gas pedal story because I have the same problem with the purchased master after the accident.

    The problem turned out to be a frayed pressure sensor cable in the air conditioning system, behind the headlight on the passenger side. In my car, the front reinforcement was slightly dented, making the cable more exposed to abrasion. Try to simply disconnect this sensor, it helped me.

Topic summary

The discussion revolves around a Renault Trafic 2.5DCi (G9U 730) from 2006 that exhibits no response when the accelerator pedal is pressed, maintaining a constant 1100 rpm. Initial troubleshooting involved measuring the voltage from the engine controller to the gas pedal, which showed values around 5.14V. Despite replacing the pedal, the issue persisted. Further investigation revealed a potential connection problem between the controller and the pedal, with suggestions to check specific pins for voltage. Ultimately, it was determined that the issue might stem from chip damage in the engine controller. Another user shared a similar experience, identifying a frayed pressure sensor cable in the air conditioning system as the cause of their problem, suggesting that disconnecting this sensor resolved their issue.
