A fault code doesn’t yet mean the unit or sensor itself is faulty: often it’s the plug and connector leading to it.
Possible causes
- Carbon on the throttle — the plate doesn’t close fully
- No relearn (adaptation) was done after cleaning or replacing the throttle
- Worn sensor track
- Sensor connector or wiring: corrosion, an open circuit, a chafed wire
What you can do yourself
- Clean the carbon off the throttle body and check the connector.
- After cleaning or replacing, run a throttle relearn (adaptation).
- The car may go into limp mode: weak pull, revs won’t rise.
- If the car stops responding to the gas pedal completely while driving, turn on the hazard lights, pull over to the shoulder and stop. If it still drives but responds poorly, you can drive on carefully, but don’t put off the check.
Stop and don’t drive on if:
- The Check Engine light is flashing
- The temperature gauge is in the red or the overheating light is on
- The red oil pressure light is on
- Smoke from under the bonnet, a burning or petrol smell
- Strong jerking, knocking from the engine, or the car barely moves
OOleg’s tip: check the connector
Often the cause is simple — there is no contact in the connector (plug). Look at the connector from the back: remove the rubber seal and you will see whether a wire is corroded or has come off completely. Corrosion shows up as green deposits. Ideally, gently pull each wire towards you one at a time: a sound wire stays in place, while a corroded one simply comes off — it needs to be repaired.
Unplug and inspect connectors with the ignition off.
