11.11 Crankshaft Position Sensor Failure
Failure code: P0016
No.
Put the ignition switch to "ON".
1
2 Pull out camshaft position sensor joint on harness,
and then use a multimeter to check if the voltage
between 1# pin of this joint and ground wire is
around 12V (battery voltage).
3 Pull out camshaft position sensor joint on harness,
and then use a multimeter to check if the voltage
between 2# pin of this joint and ground wire is
around 11.5V (power supply from ECU and the
voltage is below the battery voltage).
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 camshaft position sensor joint on harness,
and then use a multimeter to check if it is
conducting between 3# pin of this joint and
ground wire.
6 Connect the sensor connector and start the engine.
7 Use a oscillometer to check if an around 6V
square wave signal output is present in 2# signal
cable.
Note: The camshaft position sensor is an auxiliary sensor and has great effect on emission of the system.
When failure occurs in this sensor, the vehicle will be difficult to start; though the vehicle will be
basically normal after startup, driving restrictive practice will be found on the engine and the maximum
revolution of engine can not exceed 4000rpm.
