Default Broken Down ZT

Hi All

After nearly 9yrs of (almost) faultless driving, ZT finally broke down during the school run this morning. The car first lost drive, then the steering went heavy. I had enough momentum to get the car safely off the road. Whilst waiting for my inlaw to pick the kids up to take them to school, I ran the Torque app on my phone - and found a P0340 Camshaft Position Sensor "A" Circuit fault.

Will the sensor need replacing or just cleaning up? My car is 2miles away from home and on a quiet country lane so might need to organise a tow home if there isn't a quick fix!

Any help is appreciated

Thanks

Cleaning didn't help, still have the same error message.

Its like the engine wont turn over at all, but you can hear the starter motor whirring when you try to start.

Now looking for a new sensor online but I don't think its going to fix the problem

Hi Simon.
Is the the car cranking over? or is it just making a clicking sound with lights flashing when trying to start it.

You could try cleaning the spade end on the starter motor, i am also wondering if the lamba sensor as chaffed on the heat shield under the car

Good call, engine turning over at speed with loss of compression perhaps, sounds like belts.

not sure, but they seem nice and tight with no obvious signs of wear. All the writing on the belts are still white

the starter motor whirrs but the engine doesn't seem to be rotating. I tried putting the car in 1st gear, handbrake off and tried to start the car. The car lurched forward as expected (I don't know if that helps at all)

If you have had the car 9 yr and the belts have not been done then it is possible one of the timing belts have failed. (there are 3) the main belt on the KV6 is not easily visible without removing the covers. the one that is easily visible drives the alt and power steering etc and has no bearing on the timing of the engine.

Are all the belts turning when cranking. It's possible that a belt may not have snapped but have stripped the teeth. This would result in no signal from the cam sensor as the cams aren't turning to trigger the signal.
