Title: Power loss camshaft sensor fault
Post by: ryanbrook on 25 July 2013, 19:12

Timing belt got done and after there was a dramatic power loss. Was reading camshaft position sensor - implausible. Got it in the garage and the timing was out   Anyway they sorted timing out and changed cam sensor. Was back to normal for one day then back to losing power again. Any ideas. Car is a 1.6

Checked the spark and fuel? could be MAF or lambda sensor?

Lambda has been changed. Forgot to mention. Camshaft position sensor - implausible signal intermittent is still reading on vagcom. Don't understand how though if it has be changed and code cleared after

Have you checked the wiring to the CPS?

I haven't but I think vagcom would read camshaft position sensor no signal rather than implausible if connection was broke

It sound's like the timing off or the cam adjuster seals

I'm thinking timing, but its been done twice by two different people.

Take it to another garage, and ask them to check the timing

Proberly going to be my best bet I think. Are they hard to get right.

For the competent mechanic, should be easy
