Checking Components

Check the fuel and residual pressure for leaking injectors.

Check that the oil level is between the minimum and maximum markings on the dipstick.

Check the engine oil visually for contaminants.

Check the mass air flow (MAF) sensor. Read off its correction factor. The value must be between 0.8 and 1.2.

HINT: If the above fault-tracing does not remedy the fault, try replacing the heated oxygen sensor (HO2S), as the diagnostic trouble code (DTC) can also be stored by a damaged heated oxygen sensor (HO2S). 

Remedy as necessary.
