Help - Isuzu DMAX / DTEC 4J crank sensor wiring

1
Hi, I need some help with checking the wiring on a 2009 Isuzu DMAX/DTEC 3.0TDI 4J engine

Vehicle is cranking but not starting and I get a Crank Sensor fault. I replaced the sensor but still not starting.

I checked the wiring and tested on the plug for the crank sensor (see pic) on pin 1 and 3 I am getting 4.8V and pin 2 is ground

As the Cam Sensor is exactly the same I checked the wiring there as well and getting the exact same readings.

I tested for continuity from the sensor plugs and the ECM plug and there does not seem to be any break in the wire. I tested across pin 1 and 3 for continuity and there is no short in the wires.

Are the values I am getting correct???

possibly a stretched timming chain or the pick up of the cranksensor - where it picks up from the teeth are bent or 1 is bent out of place .


1: Check the connection to ground (pin 2).
Turn the ignition on. Measure the voltage on pin 2. Is it between 0 and 0.2 V?

2: Check the connectivity of pin 1.
Measure the resistance between pins 1 and B 58 (E1 Engine control unit). Is it less than 1 Ω?

3: Check the connectivity of pin 3.
Measure the resistance between pins 3 and B 37 (E1 Engine control unit). Is it less than 1 Ω?

4: Check the shielded wire.
Measure the resistance between pins 1 and B 38. Is it infinite?

5: Check the shielded wire.
Measure the resistance between pins 2 and B 38. Is it infinite?

6: Check the shielded wire.
Measure the resistance between pins 3 and B 38. Is it infinite?

Pin number Wire colour Component Pin number Wire colour
1 Yellow E1 Engine control unit B 58 Yellow
2 Blue E1 Engine control unit B 39 Blue
3 Green E1 Engine control unit B 37 Green
