11.12 Craftshaft Position Sensor Failure

Failure codes: P0321, P0322, P0219

No. Operating steps Result Follow up steps

1 Put the ignition switch to “ON”. Next step

Yes Check the circuit 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.

No Next step

Yes Next step 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.

No Check circuit and

ECU

Yes Repair or replace

the harness

4 Use a multimeter to check if it is break or short

circuit between 79# pin of ECU and 2# pin of

sensor joint.

No Next step

Yes Next step 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.

No Replace the sensor

6 Connect the sensor connector and start the engine.

Next step

Yes Check other part 6 Use an oscillometer to check if signal waveform

output is present in signal cable.

No Replace the sensor

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.
