Checking the fuel injection system

Check the intake system for air leakage.

HINT: Air leakage in the intake system can occur through the evaporative emission system (EVAP) valve, the secondary air solenoid valve or the power brake booster.

Check the fuel pressure.

Test drive the car for approximately 10 minutes.

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

Note. There must not be any air leakage when this test is carried out.

Remedy as necessary.

Checking the status

  1. Start the engine. Read off the diagnostic status and fault status for the diagnostic trouble code (DTC) by selecting the relevant diagnostic trouble code (DTC) from the list. Increase the engine speed to 2500 RPM until the diagnostic is "Complete". Check whether the fault is permanent or intermittent. Read off the diagnostic trouble code (DTC) fault status when the diagnostic status is "Completed". HINT: In some cases several functions of the component will be diagnosed. The affects the amount of time taken to run the diagnostic. The fault is permanent if the fault status is "Fault found". If the fault status is "No fault found" the fault is intermittent and not presently active.

Checking components

Check the exhaust system for air leakage.

Check the cable for a short-circuit to supply voltage or ground.

Check between

  1. The cable between engine control module (ECM) terminal #A42 (#A42) and heated oxygen sensor (HO2S) terminal #5
  2. The cable for pump current between engine control module (ECM) terminal #A24 (#A24) and heated oxygen sensor (HO2S) terminal #6
  3. The cable for calibration current between engine control module (ECM) terminal #A28 (#A28) and heated oxygen sensor (HO2S) terminal #2.

Check the cable between engine control module (ECM) terminal #A41 (#A41) and heated oxygen sensor (HO2S) terminal #1. Check for an open-circuit.

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

Check the exhaust system for air leakage.

Check the cable for a short-circuit to supply voltage or ground.

Check between

  1. The cable between engine control module (ECM) terminal #A44 (#A44) and heated oxygen sensor (HO2S) terminal #5
  2. The cable for pump current between engine control module (ECM) terminal #A25 (#A25) and heated oxygen sensor (HO2S) terminal #6
  3. The cable for calibration current between engine control module (ECM) terminal #A69 (#B9) and heated oxygen sensor (HO2S) terminal #2.

Check the cable between engine control module (ECM) terminal #A43 (#A43) and heated oxygen sensor (HO2S) terminal #1. Check for an open-circuit.

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

Remedy as necessary.
