Title: Premature Cam sensor failure
Post by: Jukeboxnut on 27 May 2014, 21:23:14

I replaced the cam sensor on my wife's 1998 1.8 Vectra estate just after I bought it 6 years ago and it has been fine since until 2 months ago when it failed, not a bad run for a cam sensor.  I replaced it with a genuine Siemens part  (awkward job on the fwd Veccy) and all seemed fine until the wretched thing failed again last week.  When I removed the offending item there was a deep radial scuff mark on the plastic sensor body where the camshaft pulley had been rubbing against it.  When checking it against the original it was obvious that the metal blade was slightly bent causing the plastic body to rub against the pulley when bolted in position.  I had not checked this when fitting so be warned that even Siemens units can be badly formed and check the shape before fitting as once in position it is hard to check the clearance.

I hope the sensor I fitted this time lasts another six years.
