Hi all,
2005 Navara zd30
I have a problem with the engine warning light coming on after about 10 to 15 minutes driving, the car seemingly goes into limp mode, no power and the tacho does weird stuff, if idle-ling around it occasion gives a boost of fuel. It's starts fine and runs fine until about 10 to 15 min driving.
I've cleaned all the earth connection I can find. The codes that come up are 0407 and 0702.
I've taken the Crank Pos Sensor out, can you test this, I've tried moving a spanner past the sensor with an olm meter on the red and white pins, but this doesn't induce any movement in the reading.
Any help will be graetfull
Cheers

there is testing procedure in the manual.

it could be crank sensor, also can be interference which screws up the sensor signal.
also can be the injection pump ecu.
do the cheap stuff first.
