807 Code P0020 on HDi engine??!*

[michael-rv]

Hi All

New to this site -looks very useful!

Has anyone seen this code on an 807 - 2.0 HDi? My list shows Variable Valve Timing fault, but my diesel doesn't have it?

Usual poor power, etc. Always starts first time, but won't rev, although when warm it has occasionally cleared itself, engine management light went out, seemed to be full power. Then the next day, same thing!

Any suggestions?

Thanks

Cam position fault as far as I remember. Was the timing belt ever done? What mileage have you?
I'd be checking the condition on the belt ASAP.

Hi

Thanks for responding. Cambelt was changed recently - engine rebuilt after belt failure! I bought the car to repair it, went through the usual nghtmare of seized injectors! It had done 75000 miles.I was meticulous about the camshaft timing - re-painted the sprockets and links, treble-checked timing locked cams using steel pins - I'm pretty sure it went back correctly. The "Anti-pollution Fault" message didn't show up immediately though. What's confusing me is the problem is not constant, and can clear suddenly. Seems to improve as it warms up.

Ok, Check the airgap of the cam position sensor. The sensor too far away from the pickup may cause same bother.
