What does this fault code mean?
Although the code is named open circuit, it concerns the PWM (pulse-width modulated) control signal to the throttle motor. It can also be set when the throttle output stage inside the engine control module becomes too hot.
Possible causes
- Loose contacts, raised contact resistance or oxidised connections
- An open circuit in the signal wire
- Damaged throttle unit
What you can do
- 1Check that the fuses are intact
- 2Read the code with the ignition on and see whether it is still active
- 3Check the connectors at the throttle unit and the engine control module for looseness, contact resistance and oxidation
- 4Look for breaks and damage on the signal wire to the throttle unit, and use a multimeter to confirm it is not broken
- 5If the fault remains, have a workshop with diagnostic equipment check the throttle unit and the engine control module
Symptoms you may notice1
- Poorer engine performance
What the fault can affect1
- Engine torque may be limited
General guidance for car owners. Diagnosis on the car can point to a different cause.
