- Engine ECM pin B40 to ground
(temperature dependant - see circuit
diagram resistance data)
3 Check cable continuity:
- Engine ECM pin B40 to sensor pin 1
- Ground to sensor pin 2
4 Check cable for short circuit:
- Engine ECM pin B40 to Engine ECM
pin A01
5 Check sensor resistance:
- Sensor pin 1 to sensor pin 2
(temperature dependent - see circuit
diagram resistance data)
