Hi

Please help!

Rover 75 KV6, no start, throwing code P0340 Cam Sensor "A circuit", so we change the sensor for a new one. Car then starts and runs perfectly. Twice, then same thing, wont start, same code comes back. Freezing the sensor makes no difference.

So we order another new cam sensor. Car starts again immediately, and runs all day with perhaps seven shut offs. Then in the evening no start, same code.

Car ECU is not damp and electrical cleaner has been used. Ditto other connections.

Only other clue is that the odometer display has been coming on with the ignition off and key out. Disconnecting the battery fixes that.

There seems to be good fuel pressure. It sprays out aggressively from the fuel rail when tested.

If anyone has any suggestions please! The car is going to be scrapped if this cannot be fixed. Its just costing too much.

Many thanks in advance.
