Hello Everyone

Over the Chistmas break my 2.8 started cutting out sometimes when my revs lowered, I could feel the engine would run a little rough, but it would start ok straight away. Then it would run fine for half an hour then it would do the same.. cut out. The malfunction light on the dash would come on.

The injector pump is tired, I have put an advance plate on it. The pump has done 270000 k

I have cleaned the MAF, I have cleaned the crank angle sensor but fault code still flashes 47 which is the crank angle sensor.

Anyone had the same problems and were able to fix?

Cheers

Hello everyone

I did get some advise from the GU 2.8 specialist Benno and he suggested the I test the sensor with 2 AA batteries in series with a multimeter and run a magnet across the sensor and see if the multimeter increased it voltage.

I did the test and it did seem to respond.. so I was then clueless.

Anyway the ECU was still indicating a fault with the Crank angle sensor code 47. I bit the bullet and got a new sensor. Took for a drive and problem seems to be resolved. Code now flashing is 55 which means all good.

I though that I would share this info as maybe someone may get this problem down the track.

One question for the technical boys. Can these sensors fail/work intermittently? as the vehicle would run fine sometimes with the old sensor and sometimes it would run like shhit

Good that you did reply with a resolution. Might help someone in future...

Sensors are funny things, coming from a marine mechanical point of view, yes they can reek havok when trying to diagnose a problem. one minute you test it and its fine, the next minute a fault code gets thrown up saying your engine is about to go bang.
9 times out of 10 its just a faulty sensor.
