18041/P1633 - Accelerator Position Sensor 2 (G185): Signal too Low

Possible Symptoms

  • Unknown

Possible Causes

  • Wiring and/or connections faulty
  • Sensor (G185) faulty

Possible Solutions

  • Have a look at the Pedal Position Sensor assembly, not the Throttle Body.
  • Check all connections between ECU and accelerator pedal - of course the pedal itself could be defective too.

Special Notes

  • There are 2 sensors in the accelerator pedal, both measure the same except that they are working in opposite directions. This means one counts from 0 to 100, while the other one counts from 100 to 0.
