Vehicle
Holden Astra TS 2001 Z18XE
Symptom:
Engine fault light on and trasmission stuck in 3 gear
The client had dropped of the vehicle for diagnostics and we deicided to test drive the vehicle to confirm the symptoms, we found that the engine light and the service vehicle soon light is on.
Diagnostics
We used the Bosch KTS scan tool to diagnose all the system faults with the vehicle and the faults came back with P100, air flow meter in the Engine ECU and a C0256, engine torque reduction malfunction in the transmission, this vehicle is an OBD2 Compliant vehicle and the fault codes are looked up from the OBD2 database table.
The clearing of the fault codes was not a success, after start up the fault codes came back, we used the current data/live data to check the output of the air flow meter and it read 0 kg/m
The air flow meter was obviously not working, so manual testing of the sensor had to be undertaken.
The wiring diagram shows the 3 wires connecting to the air flow meter, there is:
- Power feed to turn the sensor on (red)
- Output signal to Engine ECU (green)
- Ground. (Yellow)
- Intake Temperature Sensor Output (grey)
