CHECKING THE FUEL INJECTION SYSTEM, IGNITION SYSTEM AND COMPONENTS

Note. In the event of diagnostic trouble codes (DTCs), that affect camshaft control or camshaft reset valve, these must be fault-traced first.

HINT: In certain cases, the engine control module (ECM) can determine which cylinder has misfired.

Check the fuel level in the fuel tank.

Check that the engine oil level is correct.

Look for moisture in the electrical terminals for the ignition coils and in the spark plug wells.

Check the spark plugs. Search for damage in the insulation and other damage.

Check the engine intake system for leakage.

Check the crankcase ventilation. Check for blockage.

Check the fuel pressure and residual pressure.

Check the compression of the engine.

Remedy as necessary.

CHECKING COMPONENTS AND CONNECTIONS

  1. The status of the valve can be determined by activating the quick test for the EVAP valve. The test sends pressure pulses through the valve so that the functionality of the valves can be checked. The fault is permanent if a fault is detected in the evaporative emission system (EVAP) valve when running the quick test
  2. Engine idling during the entire test. Activate the evaporative emission system (EVAP) valve quick test. The test takes a few seconds to carry out. The tool displays the ranking value as a value between 0 and 255. The functionality is poor if the value is 128 or higher. Check the hose/hose connectors between the evaporative emission system (EVAP) valve and canister. Check for damage, blockage or pinching. The valve may need to be cleaned or replaced. The functionality is good if the value is below 128. If this is the case, check the hose/hose connectors between the EVAP valve and the intake manifold. Check for damage, blockage or pinching. Note the read ranking value. Remedy as necessary. Other information see «LOCATION OF COMPONENTS, ENGINE COMPARTMENT»(ref-466647-S29464904412012042500000)
  1. Continue Refer to «VERIFICATION»(ref-466658-S20525700662012042500000)

HINT: After carrying out the repair, check that the fault has been remedied.

  1. Ignition off
  2. Reinstall the connectors, components etc.
  3. Restart the quick test of the EVAP valve and check the ranking values to establish if the work carried out has remedied the problem
  4. Engine idling during the entire test. Activate the evaporative emission system (EVAP) valve quick test. The test takes a few seconds to carry out. Check that the ranking value is lower than 128, and that it is significantly lower than the previous value. A value below 128 indicates that the fault has been remedied and the function is OK.

  1. YES VERIFIED: Troubleshooting has been completed.
  2. NO Refer to «INFORMATION»(ref-466658-S39819082472012042500000)

The fault should have been detected and remedied. As this is not the case fault-tracing has failed.

Exit fault-tracing for this diagnostic trouble code (DTC) or make another attempt.

  1. The status of the valve can be determined by activating the quick test for the EVAP valve. The test sends pressure pulses through the valve so that the functionality of the valves can be checked. The fault is permanent if a fault is detected in the evaporative emission system (EVAP) valve when running the quick test
  2. Engine idling during the entire test. Activate the evaporative emission system (EVAP) valve quick test. The test takes a few seconds to carry out. The tool displays the ranking value as a value between 0 and 255. The functionality is poor if the value is 128 or higher. Check the hose/hose connectors between the evaporative emission system (EVAP) valve and canister. Check for damage, blockage or pinching. The valve may need to be cleaned or replaced. The functionality is good if the value is below 128. If this is the case, check the hose/hose connectors between the EVAP valve and the intake manifold. Check for damage, blockage or pinching. Note the read ranking value. Remedy as necessary. Other information see «LOCATION OF COMPONENTS, ENGINE COMPARTMENT»(ref-466647-S05486220892012042500000)

HINT: After carrying out the repair, check that the fault has been remedied.

  1. Ignition off
  2. Reinstall the connectors, components etc.
  3. Restart the quick test of the EVAP valve and check the ranking values to establish if the work carried out has remedied the problem
  4. Engine idling during the entire test. Activate the evaporative emission system (EVAP) valve quick test. The test takes a few seconds to carry out. Check that the ranking value is lower than 128, and that it is significantly lower than the previous value. A value below 128 indicates that the fault has been remedied and the function is OK.

see FAULT-TRACING INFORMATION

No fault-tracing has been developed for this diagnostic trouble code (DTC). The diagnostic trouble code (DTC) for this fault is stored first in the central electronic module (CEM), then in the engine control module (ECM). This diagnostic trouble code (DTC) can not be erased before the diagnostic trouble codes (DTC) in the central electronic module (CEM) has been remedied and erased.

First read off the diagnostic trouble codes (DTCs) in the central electronic module (CEM). Fault-trace and remedy as necessary. This diagnostic trouble code (DTC) can then be erased.

CHECKING STATUS

  1. Ignition on. Check whether the fault is permanent or intermittent by reading the signal from the fuel level sensor (via the central electronic module (CEM)) and checking that it is within its permitted range. Also check that it moves if the car is rocked gently, before stabilizing at a reasonable level. An incorrect signal indicates that the fault is permanent. The fault is intermittent if the signal is within the permitted range. HINT: If the tank is completely full, their may be no noticeable change in level if the car is rocked.
  1. Continue Refer to «CHECKING CONNECTOR»(ref-466658-S08625047262012042500000)

CHECKING CONNECTOR

Check the fuel level sensor connector and terminals. Check for contact resistance. Check for oxidation.

Remedy as necessary.

CHECKING THE COMPONENT

  1. Slacken off the evaporative emission system (EVAP) valve
  2. Connect a vacuum pump to the evaporative emission system (EVAP) valve terminal (B). Pump a vacuum. Check that there is no leakage through the evaporative emission system (EVAP) valve by listening to and checking via the pump gauge that the pressure is stable
  3. Connect the Evaporative emission system (EVAP) valve connector
  4. Ignition on
  5. Activate the evaporative emission system (EVAP) valve. When the Evaporative emission system (EVAP) valve is activated, the valve opens and clicks. Check on the pump gauge that the vacuum drops (the pressure evens out) when the evaporative emission system (EVAP) valve opens. If the function is OK, there must be no leakage when the evaporative emission system (EVAP) valve is closed (stable pressure on the pump gauge) and the vacuum must drop when the evaporative emission system (EVAP) valve opens (the pressure evens out). The evaporative emission system (EVAP) valve is damaged if the function is faulty. If the function of the Evaporative emission system (EVAP) valve is OK, check: The hose and hose terminals between the Evaporative emission system (EVAP) valve and the intake manifold. Check for leakage and blockages Check the hose and hose terminals between the EVAP canister and the Evaporative emission system (EVAP) valve. Check for leakage and blockages. Remedy as necessary.
