322 - Position of Camshaft Relation Crankshaft, Bank 1

P1340

322 Position of Camshaft in Relation to Crankshaft, Bank 1 - Below Limit

Diagnosis conditions
- Idle speed
- Reference mark recognized
- Engine speed between 600 rpm and 1.200 rpm.
- Engine temperature greater than 40 degree C
- No fault in camshaft position sensors
- Reference mark OK
- No fault in camshaft adjustment
- No fault in engine temperature
- No fault in camshaft adjustment output stage

Possible fault cause
- Allocation of camshaft to inlet camshaft incorrect

Affected terminals

-

Diagnosis/Troubleshooting

NOTE: This fault is stored if the engine was disassembled and the allocation of the camshaft to the inlet camshaft was incorrectly set.

Figure 2:

1 - Voltage not applied yet, valve in output state
2 - Exponential voltage increase, magnetic field is built up, increase of the spring preload force
3 - Valve starts to move, spring force increases, valve reaches end position
4 - Exponential voltage increase, current limitation through selfinduction of the coil
