Cam Sensor Gone ... Again!
« on: November 09, 2009, 14:30:57 PM »
As the title really  >:(

Had the Ecotec just over a year now and my third cam sensor has turned up it's toes. I wouldn't mind so much if I was doing a high mileage but this last one has done less than 1000 miles!

It's definitely the cam sensor as the paperclip test confirms it.

Anyone any idea on why they're not lasting?

I have noticed a slight mark on the front of the sensor where one of the cam pulleys has rubbed - but it is so slight that you can't feel any ridge to it.

The other thing is that if I restart the car with the engine warm, the sensor sometimes works okay and the EML stays off.  ???

Anyone offer any explanations?

are you fitting decent quality (GM/autovaux) parts or cheap bitz? If cheap stuff thats why they are cheap :P

Title amended.

I've been using Siemens sensors. I did have an unbranded sensor that didn't work straight from the pack so have only ever used the Siemens branded ones at 20-25 quid a time.

Are you definately getting the stored code cleared after you change the sensor?

Yes, I'd disconnected the battery and left it for about 36 hours one weekend. EML was clearing as it should. The 1000 miles was over a period of about 6 weeks during which it was running fine.

Try disconnecting the battery again overnight and see how long it takes to throw the code up again. Are the connections on the sensor etc clean?

All contacts are clean and I've checked the cabling back to the ECU. I've also tried swapping the ECU for a spare I have (one that's been disconnected for the past 6 weeks since the last sensor was replaced) and still getting the EML on.

Sadly its a common fault on the ecotec and im not aware of any better alternative.

All I'd say is make sure you use the correct part, get genuine ones from AutoVaux, make sure you erase the code, and if any wires have been exposed by rubbing on the PAS belt, then make sure you rewire and re route them the correct way.

Cheers VII CKS,
Done all of those including the rewire and re-route, proper soldered joints with heat-shrink sleeving, routed neatly well away from any moving parts. Only thing was that I didn't get the sensors from Autovaux but they are Siemens branded.
Twenty five notes per 1000 miles? Anyone know how to re-program an ECU to ignore the cam sensor? It's worth the cost of a couple of sensors!  :D

I'd get the part from AutoVaux directly, they know what they are dealing with, with Ecotec's you got the early/late type engine just like the XE. Might be slight variations in the sensor. I'd order parts from them and if they go wrong they should be under a year guarantee at least.

^^^^^I agree. The reputation the Ecotec has for sensor problems is much worse than the reality. There must be an underlying reason why you're getting through so many

It's true, that way if he gets a sensor from AutoVaux he knows he definately is getting the right part, and the best quality part as well, and they shouldn't cause an issue, even after 1000 miles.

That's my feeling about it too but I can't see what it would be. ???

Okay, thanks for your replies, I'll get one from Autovaux and see how long that lasts.  :-\
