Checking for blockage between the fuel tank pressure sensor and the fuel tank

HINT: If "small leak" is detected after a completed quick test of the fuel tank system, it may in certain cases be due to a blockage between the fuel tank pressure sensor and the fuel tank.

HINT: The method below is used to determine whether the detection of "small leak" after completed quick tests is caused by a blockage between the fuel tank pressure sensor and the fuel tank. It can be carried out by running the test with the fuel tank filler cap removed. Normally a "large leak" is detected with the fuel tank filler cap removed. If a "small leak" is detected with the fuel tank filler cap removed it indicates a blockage between the fuel tank pressure sensor and fuel tank.

HINT

Note. If the EVAP canister fills with the fuel vapor the test is interrupted. The EVAP canister fills with fuel vapor faster if the evaporative emission system (EVAP) valve is operating and the fuel tank filler cap is removed. Start the quick test directly after engine start and do not let the engine run at idle speed for longer than necessary.

1. Remove the fuel tank filler cap
2. Engine idling
3. Start the quick test with the fuel tank filler cap removed. In particular check the fuel tank pressure (red line) when the "large leak" test is running. If a "large leak" is detected with the fuel tank filler cap removed, the most likely cause is leakage. Continue fault-tracing according to "small leak". If the test is cancelled or "small leak" is detected with the fuel tank filler cap removed and the fuel tank pressure (red line) falls more slowly than normal during the test it may be due to a blockage in the hose or hose terminal between the tank and the fuel tank pressure sensor. This can be fault-traced by removing the hoses to the evaporative emission (EVAP) system components one at a time and carrying out a quick test between each operation. If a "large leak" is detected after the quick test when the hose has been disconnected the fault is in the direction of the airflow (calculated from the hose that has been disconnected). HINT: The direction of airflow during a quick test can be calculated from the fuel tank: fuel tank, evaporative emission system (EVAP) canister, evaporative emission system (EVAP) valve. The fuel tank pressure sensor measures the pressure in the hose between the fuel tank and the evaporative emission system (EVAP) canister. HINT: If the hose for the EVAP canister is detached from the fuel tank and a "large leak" is detected, there is a blockage in the tank hose terminal. Remedy as necessary. Reset all the components. Carry out a quick test of the tank system before the car is delivered to the customer. Select a suitable alternative to continue: Continue "small leak" fault-tracing Refer to «Small leak»(ref-408511-S15074939592011071200000) Finish. OKAY: Troubleshooting has been completed.

1. Start the engine. Read off the camshaft shift angle and the camshaft shift angle, desired value. At idle and at 4000 rpm, check that the camshaft's shift angle (desired value) corresponds with the camshaft's shift angle by an accuracy of 3 degrees. The difference between the values can be read off in the lower display. Carry out the check at stable engine speed (RPM). NOTE: Before the engine speed (RPM) stabilizes, the difference between the values can be greater than 3 degrees for approximately 1 second, this is normal. If the values correspond by an accuracy of 3 degrees, this means that the fault is intermittent. If the values deviate more than 3 degrees, this means that the fault is permanent.

Scheme 999

Continuous variable valve timing (CVVT) control, general

The engine combustion can be improved by changing the shift angle of the camshaft. This reduces emissions, gives lower fuel consumption and better performance. The shift angle of the camshaft is controlled by the control module which changes the pulse ratio of the reset valve. The pulse ratio of the reset valve affects the variable valve timing unit which changes the camshaft position compared to the crankshaft position (CKP). This ensures quick and precise control of the shift angle of the camshaft.

Definition of "Camshaft shift angle" (X°)

When the camshaft (A) is set at the factory it is aligned to top dead center (TDC) on the crankshaft which is 0° (B). The camshaft position when aligned to the crankshaft TDC is the camshaft 0 position (0°). With continuous variable valve timing (CVVT) the camshaft 0 position is offset, the value of the offset of the camshaft 0 position is the camshaft shift angle (x°).

Scheme 1000

The control module interpretation of camshaft shift angle

(The illustration shows the camshaft shift angle at 10°)

The camshaft shift angle is checked by the control module by comparing the position of the crankshaft with the position of the camshaft.

The camshaft (A) is divided into 4 flanks per camshaft rotation (flanks 1-4). The angles are: between flanks 1-2 = 103°, flanks 2-3 = 90°, flanks 3-4 = 90° and flanks 4-1= 77°. The difference in angle between the flanks allows the control module to determine which flank is currently detected and therefore which cycle the camshaft is in. The control module detects the flanks using the signal from the camshaft position (CMP) sensor.

The crankshaft has four reference positions, one for each camshaft flank. Two reference positions are detected for each crankshaft rotation. Two engine rotations are required to detect all the camshaft flanks: flank 1 at 0°, flank 2 at 206°, flank 3 at 386° and flank 4 at 576° (flanks 3 and 4 are detected during the second rotation of the engine).

The reference positions on the crankshaft correspond exactly to the respective camshaft flank when the camshaft shift angle = 0°. The control module detects the reference positions for the camshaft flanks using the engine speed (RPM) sensor signal.

If, for example, the camshaft shift angle is +10°, the flanks correspond to the crankshaft reference positions for the respective camshaft flank and +10° from the crankshaft reference positions.

Example

If the camshaft flank 1 is detected at 10° from the crankshaft reference position for flank 1 (0° +10°), the camshaft shift angle is 10°. If the camshaft shift angle is the same (10°), flank 2 is detected at 216° (206° + 10°), flank 3 at 396° (386° + 10°), and flank 4 at 576° (586° + 10°). The shift angle can be positive (+) or negative (-) depending on whether the flank is detected before or after the different crankshaft reference positions.

Scheme 1001

Adaptation of the camshaft shift angle, flanks 1-4

(The illustration shows the adaptation of the camshaft shift angle at 10°)

When the engine has the "basic setting", the ideal value for the camshaft adaptation value is 0°. The different camshaft flanks correspond exactly with the reference positions for the respective flanks. These values may deviate because of tolerances in the materials and installation. By adapting these deviations the camshaft shift angle can be exact.

Adaptation is carried out as follows

Camshaft control not active, the pulse ratio on the camshaft reset valve is set to approximately 90% by the control module. This means that the camshaft 0 position (mechanical resting position) is assumed and the camshaft angles (x°) for flanks 1-4, which are then detected by the control module, are the adaptation values which are stored. (The adaptation values will be 0° if the camshaft adjustment in relation to the crankshaft is exact). When the control module operates the camshaft to a particular target value, the stored adaptation value is added to the control module's target value.

Example: The control module has adapted flanks 1-4 to an average value of +10° (as the result of an incorrectly set camshaft for example). When the control module needs to operate the camshaft to +10° (target value), the adaptation value is added to the target value which then gives a target value of 20° (10° +10°=20°).

The control module can adapt 20°. A diagnostic trouble code (DTC) is stored in the control module if the adaptation is higher or lower than 10°.

Other information

1. If the timing belt is incorrectly positioned by one tooth on the variable valve timing unit, this corresponds to approximately 17° on the crankshaft. This gives a theoretical adaptation value of 17°.
2. If the timing belt is incorrectly positioned by one tooth on the variable valve timing unit, this corresponds to approximately 34° on the crankshaft. This gives a maximum adaptation value (20°)
3. The setting of the variable valve timing unit in relation to the camshaft and crankshaft affects the adaptation value (between -20° and +20°)
4. If the slide in the camshaft reset valve has jammed, the camshaft will be operate at maximum angle. This which will give an adaptation value at the maximum limit (+20° or -20°)
5. The function of the variable valve timing unit affects the adaptation value (between -20° and +20°).

Check the resistance on camshaft reset valve between terminals #1 and #2.Resistance must be approximately 3.7 ohms.

Check the signal cable between Engine control module (ECM) terminal #A13 and camshaft reset valve terminal #2. Check for an open-circuit, short-circuit to ground and short-circuit to voltage.

Check the power supply cable between system relay terminal #5 and camshaft reset valve terminal #1. Check for an open-circuit.

Check the engine oil level and quality. Check for contaminants in particular.

Check the engine oil pressure.

Remove the camshaft reset valve. Check the oil ducts in the cylinder head for the camshaft's reset valve. Check for blockage and contamination.

Note. If it is suspected that there are any contaminants in the camshaft reset valve it should be replaced.

HINT: The diagnostic trouble code (DTC) can also be caused by a damaged variable valve timing (VT) unit.

Remedy as necessary.

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

1. Ignition off
2. Reinstall the connectors, components etc.
3. Ignition on
4. Start the engine. Check the camshaft adaptation by reading off the adaptation values of the camshaft (flanks 1-4). All values must be between -7° and +7°. Turbocharged engines: When checking, the accelerator pedal (AP) must be depressed slightly but the engine speed must be below 1200 rpm. Naturally aspirated engines: When checking the engine must be idling. HINT: Theoretically the values for flanks 1-4 should be the same, however because of mechanical tolerances the values may vary between the different flanks by approximately 2°.

Are all the adaptation values correct?

1. YES VERIFIED: Troubleshooting has been completed.
2. NO Refer to «Information»(ref-408511-S20846500172011071200000)

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.

Checking the fault type

Read out the adapted values for the camshaft. There are 4 values, one for each flank.

If one of the adaptation values is 20 degrees, the camshaft reset valve has stuck. Replace the camshaft reset valve.

If one of the adaptation values is less than 9 degrees, the camshaft reset valve is defective. Replace the camshaft reset valve.

If any of the adaptation values are between 10 and 19 degrees, the variable camshaft must be adjusted in relation to the crankshaft. Adjust the camshaft.
