VERIFICATION
HINT: After carrying out the repair, check that the fault has been remedied.
Scheme 131
Scheme 132
- Ignition off
- Reconnect the connectors, reinstall components etc.

- Connect VCT2000 to the data link connector (DLC) without switching off the engine. NOTE: If the engine is switched off, the stored fault status will be erased and the test drive will have to be repeated. Read off the dynamic for the front heated oxygen sensor (HO2S). The value should be higher than 1.0.
Is the value OK?
- YES VERIFIED: Troubleshooting has been completed.
- NO Refer to «INFORMATION»(ref-500319-S36749656832012091100000)
FAULT-TRACING INFORMATION
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.
see FAULT-TRACING INFORMATION
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 CONNECTOR
Check the fuel level sensor connector and terminals. Check for contact resistance. Check for oxidation.
Remedy as necessary.

HINT: After carrying out the repair, check that the fault has been remedied.
- Ignition off
- Reinstall the connectors, components etc.
- Ignition on. Read off the signal from the fuel level sensor (via the central electronic module (CEM)). Check that the signal is within its permitted range. The level should change if the car is rocked gently, before stabilizing to a reasonable level. A reasonable signal indicates that the fault has been remedied. HINT: If the tank is completely full, their may be no noticeable change in level if the car is rocked.
Is the signal within its permitted range?
- YES VERIFIED: Troubleshooting has been completed.
- NO Refer to «INFORMATION»(ref-500319-S03327338942012091100000)

CHECKING THE COMPONENT
- Slacken off the evaporative emission system (EVAP) valve
- 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
- Connect the Evaporative emission system (EVAP) valve connector
- Ignition on
- 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.

Scheme 135
- Activate the test by pressing on the symbol for VCT2000.
- Read off initial parameters and check them according to start conditions for performing the test.
- Press the button "Start" to start the quick-test.
- Check that the test has started. Parameters run status shall go to "In progress" and the test phase shall go to "Reference". NOTE: If the test does not start, check that the start conditions are fulfilled. When the reference phase is finished, check of the tank system starts. The pressure in the tank starts to increase. Within 15 minutes the Engine control module makes a decision as to whether there is leakage in the tank system or not. The test is finished.
- Check parameters for test result and follow relevant instructions below. NOTE: In the event of a the results from the estimated leakage must be entered in NOTE: Estimated leakage shall be used to get an idea of the proximity to the diagnostic trouble code limit. If the estimated leakage is very near the diagnostic trouble code limit (greater than 0.3mm), troubleshooting should probably be performed despite the Tank system, test result shows "No leakage found", especially if a diagnostic trouble code for leakage has been stored earlier. NOTE: Use diagnostic trouble code counter to see the frequency of the problem. Also use frozen values to get an idea if external conditions may have affected the result. Compare with current conditions in the workshop. Conditions for starting the quick test of the fuel tank system No DTCs related to EVAP purge valve or ambient air pressure sensor set. Battery voltage 11-15 V. Atmospheric pressure higher than 750 hPa, appr. 2500 m (8200 ft). Fuel level 0-85 %. Ambient air temperature 4-35 °C . NOTE: The battery voltage must be correct throughout the entire test. The test can take up to 15 minutes, depending on the quantity of fuel in the fuel tank. It is highly recommended to use the constant voltage charger, Midtronics PSC-550, during the test.

FUEL TANK SYSTEM, CHECK
Note. This instruction is deliberately written for use with different types of leak detecting equipment. Therefore certain components may differ on different equipment.
SAFETY
First read, see SAFETY REGULATIONS FOR HANDLING FUEL .
Note. Follow the safety precautions for the equipment. Follow the instructions for connecting, disconnecting, use and maintenance.
HINT: Be aware of the risks of igniting the fuel. Do not let the temperature of the tank fall below 0 °C when carrying out checks.
| CAUTION | Never leave the car unattended with the tank system pressurized |
PREPARATION
Ignition off.
Seal the intake air hose for the carbon filter container. (A rubber plug is sufficient on certain models.)
Expose the evaporative emission system (EVAP) valve.
Disconnect the hose (1) between the carbon filter container and the evaporative emission system (EVAP) valve.
DETERMINE THE SIZE OF THE LEAK
Calibrate the equipment in relation to the definition of a major or minor leak for the relevant vehicle. See the instructions provided by the equipment supplier.
Connect the leak detecting equipment hose for gas to the detached hose.
Pressurize the fuel tank system. Check the result against the default value to determine the size of the leak.
HINT: The supplier's instructions often contain useful tips to facilitate carrying out checks.
Complete pressurization.
LOCATING LEAKAGE
Connect the leak detecting equipment hose for smoke to the detached hose.
Fill the tank system with smoke. The time taken to fill the system depends on the size and volume of the system, and the performance of the equipment.
Visually check the evaporative emission (EVAP) system, using a halogen and / or UV lamp.
HINT: The supplier's instructions often contain useful tips to facilitate leak tracing.
Stop filling with smoke.
RESETTING
Reinstall the hose between the carbon filter container and evaporative emission system (EVAP) valve.
Install the evaporative emission system (EVAP) valve.
Remove the seal at the intake air hose for the carbon filter container.

CHECKING THE THROTTLE UNIT
Note. Dirt, ice build-up or objects can cause the throttle disc to jam momentarily. This may cause the diagnostic trouble code (DTC) to be stored.
Check that the throttle module throttle is not dirty, blocked or sticking. Clean as necessary.
HINT: A film of oil covering the throttle may mean that the flame trap is not functioning correctly.
Check the throttle unit and engine control module (ECM) connectors. Check for contact resistance and oxidation.
