01 4.4i Warning Light`

[armstrob]

Hi all,

I am having a strange problem that I wanted to see if anyone had seen and might point me in the right direction.

If I do a long distance drive of approx. 250km I get the engine warning light. I asked a friend of mine with a laptop and the OPUS software to check it out and he got the following errors reported:

P0348 Manufacturer Specific
P1161 Manufacturer Specific
P0340 Camshaft Position Sensor Circuit Malfunction

After I have finished my long drive and parked up for the night the light is gone the next day. I have driven for two weeks on short drives of less than 100km a day and the fault does not show. It only seems to be on long drives.
Any help would be gratefully appreciated......

Bob.
