Fault diagnosis
When the cylinder temperature is greater than its credible upper limit or less than its credible lower
limit, the fault fl ag is set, and the common fault codes are shown in the fault summary table. Cylinder
temperature sensor failure check:
◆ First check whether the sensor harness connector is well connected
◆ Unplug the connector, check whether the sensor and the wire harness end pins are bent or
deformed, etc.
◆ Use M19mm open-end wrench to remove the sensor and check whether the sensor probe is
deformed
◆ Check the resistance between pins 【A 】and【C】
◆ Connect the connector and check the voltage between pins【A】and【C】
