Craftshaft Position Sensor Failure - Chery QQ6 Service Manual

11.12 Craftshaft Position Sensor Failure

Failure codes: P0321, P0322, P0219
No.
Put the ignition switch to "ON".

2 Pull out crankshaft position sensor joint on
harness, use a multimeter to check if it is short or
break circuit between 1# pin of this joint and 34#
pin of ECU.
3 Pull out crankshaft position sensor joint on
harness, use a multimeter to check if it is short or
break circuit between 3# pin of this joint and 15#
pin of ECU.
4 Use a multimeter to check if it is break or short
circuit between 79# pin of ECU and 2# pin of
sensor joint.
5 Pull out crankshaft position sensor joint on
harness, and then use a multimeter to check if the
two signal cables on the sensor has a resistance
value of around 1000Ω.
6 Connect the sensor connector and start the engine.
6 Use an oscillometer to check if signal waveform
output is present in signal cable.
Note: Crankshaft position sensor is the main sensor of electronic control unit of engine. If crankshaft
position sensor failure occurs, the engine will be difficult to start; acceleration performance of the engine
will be greatly restricted after startup; the maximum revolution of the engine can not exceed 3800rpm;
meanwhile, emission of the engine will deteriorate.
