Hi
I have read through some posts on this forum regarding this issue, so it may feel like groundhog day for some, but bear with me.
I have the dreaded Camshaft Position Sensor > Sensor G40 Not a Plausible Signal. This is confirmed by a Seat main dealer.
The fault manifests itself in the usual fashion, by a failed start. Re-cycling the key i the ignition several times has no effect. I have not ODBII kit so unable to reset codes.
The fault has been on the car for some time, both before and after a CAM-belt change, but as the car is running fine, good mpg, no EML and responds to requests for power in the usual manner - plus no worrying noised from the engine i am 99% the CAM-belt is OK (but i will check the teeth!)
The dealer is aware the wiring loom has been worked on in the past. An issue with the glow plug loom meant it was replaced and the new loom spliced into the existing main loom.
The dealer suggests (sic) "to jiggle the wires" and try the ignition again. This works. Like a dream.
My first questions - is sensor part of a pair located in two places? First behind the oil filter (very visible) secondly (possibly the sender unit) located in part of the engine on the driver side between the CAM-belt.
When the engine does not fire from "jiggling the wires" I work my way back to the battery, checking at every stage. Eventually i under the battery tray there are other wires possibly going to the starter motor which when adjusted, appear to allow the car to start.
My second question - could the fault though reported as the camshaft sensor be a break in the cable nearest the starter (or part of the ignition wires) or an issue between the starter and battery or a general break in the cable in this area?
No contact points are loose, simply by "moving" the cables does the engine fire.
This is of particular interest to me. Any thoughts on the wiring would be very welcome.
My final questions is on the 2004 seat leon 1.9tdi ARL, where is the G40 sensor?? So many conflicting suggestions where it is to be found.
Thank you for your time.
