Brief history.

Car running fine. No faults on Nanocom check about three weeks ago.

Parked up for best part of two weeks. Battery dead. Charged up and can crank but no start.

Nano throws up 0340, cam position sensor fault.

Read RAVE which tells me that engine will run with this fault, but flat battery makes it forget where it was.

1) Is replacement the only solution? Of course, I have a spare crank sensor but not cam.

2) If an existing fault any idea why it didn't show previously on Nanocom?

Any input gratefully received before I go underneath in the morning.

Never heard of a cam sensor actually failing yet ...

But the connectors can get oil in them and contaminate the connection... so I'd start there ..

Thanks Marty, I'll strip it all out this morning and give things a good clean.

Is there any way to bench test it?

Assuming it's a Hall effect sensor like the ABS and crank sensors, checking the resistance would be a simple place to start. If it's open circuit or very high resistance, it's likely to be dead.

Marty was right on the money.

Took the sensor out (using the proctologist's hands) because that was the only way I could get any purchase on a very stuck plug, eventually parted it and gave everything a good blast with contact cleaner.

Reassemble and away she went. Fault cleared and happy Range Rover.

Thank you!

Now you've just got to fix the oil leak that caused oil to get in there in the first place......

I'm sure you could use your Proctologists hands again though. Save you getting your own hands dirty...

Unfortunately that was my thought too, as I lay underneath. It's going to be a messy job getting the bottom end clean enough to see where it is but never mind, let's see what sense of humour my new neighbours have!

He's told me to sod off, he'd rather stick his fingers up someones arse!
