18042/P1634 - Accelerator Position Sensor 2 (G185): Signal too High

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.
