Hi All,
This is for the mate/mechanic next door, who helps me out a lot so I'd like to return a favour (and on top of that it's his mums car).
This car is excellently maintained as he's really picky and has done a fairly low mileage.
MIL on, read cam / crank sensor codes, no surprise on a Vauxhall then!
He informed me it was due for a cambelt so I said to do that first, which he did, quality kit with tensioner and pump. I also warned him about the fragile lug on the cam pulley.
After this we still get a P0340 cam sensor code.
Checked all wiring to ECU. There is no power from the ECU to the cam sensor which I believed to be a Hall sensor as it is the later type dropped in from the top behind the cam wheel (or will this be the rf excited type?) Never got involved this far with these before,new sensors and adjusting or replacing the cambelt has always got me out of trouble with these until now.
ECU has been to ATP for testing with no fault found
I intend to scope the cam / crank sensor next week but I am having trouble finding a set of reference waveforms.
