What does this fault code mean?
The engine control module (ECM) adjusts injection from the lambda sensor reading. The code is set when the correction has to be made close to its maximum at idle. The fault may lie in the mass air flow sensor, leaking injectors, the engine oil or oil level, the lambda sensor or the calculated ethanol content.
Possible causes
- Damaged mass air flow (MAF) sensor
- Leaking injectors
- Contaminated engine oil
- Oil level too high
- Damaged heated oxygen sensor (HO2S)
- Incorrectly calculated ethanol content
What you can do
- 1Check that the fuses are intact; their locations are in the owner's manual or on the fuse box cover
- 2Have a workshop measure the fuel and residual pressure to see whether the injectors leak
- 3Look at the dipstick, where the oil should sit between the two marks, and check the oil for dirt
- 4Look for leaks between the throttle body and the cylinder head
- 5Think back on how the car has been refuelled; and have a workshop check the ethanol calculation if it may be wrong
- 6Replace the lambda sensor if nothing above cures the fault, since a damaged lambda sensor can also set this code
Symptoms you may notice1
- The malfunction indicator lamp lights up or behaves abnormally
