Hi Folks. I am having problems with the signal from Cam Position Sensor (G40) on Elaine's Mk4 1.8T AUQ. The thread is at the bottom of the page. Basically whatever I do I always get Fault Code; Signal Too High. I have tried a new sensor. Different shutter wheels. Disconnecting the plug. Changing the cams. All to no avail. I am wondering if it's the wiring to the ECM? I have checked for continuity and cables appear OK, although the signal cable is not very flexible at the plug. There are actually small cracks in the plastic close to the plug. Before I start messing with the cables I thought that I'd try to check the signal from the Hall Sensor. Multimeter/Ocilloscopes are quite expensive for just one test. I already have a pretty good Multimeter anyway. Cheapest way might be a simple signal tester like this?
