What does this fault code mean?
The engine control module (ECM) checks the throttle position sensor, potentiometer 1. The fault code is set when the voltage from the potentiometer is too high.
Possible causes
- Poor contact or oxidation between the engine control module and the throttle unit connectors
- Open circuit or short circuit to supply voltage in the signal cable
- Open circuit in the ground wire shared by potentiometers 1 and 2
- Damaged throttle unit
What you can do
- 1Read the fault code status with the ignition on and check whether the fault is active. Then clear the code and road test the vehicle
- 2Check the connection between the control module and the throttle unit for contact resistance and oxidation
- 3With the connector unplugged, use a multimeter to check that the signal cable is not short-circuited to positive and that the ground lead for the potentiometers has no open circuit
- 4If no faults are found in these checks and the code returns as a permanent fault, have a workshop try replacing the throttle unit
Symptoms you may notice2
- A text message is shown in the display
- The engine has poor performance and lacks power
What the fault can affect2
- The control module works out the throttle angle from potentiometer 2 instead
- If fault codes for both potentiometers are stored together, power to the throttle motor is cut off
