That's a good thought process. Thankyou. I had before on road test performed lots of clutch pedal pressing to see if it produced the fault but it didnt seem to change the reading. I will definitely try load testing with a bulb like you suggested.

I have not had chance to drop back on to this as we are very busy at the minute but I will check the frequency against the given figures for sure. The maf has been replaced with a known good from a transit but the fault still persisted. I have checked wiring diagrams and the 12v feed has a shared fu...

Hello. I have scoped powers and grounds on various road tests put the vehicle is refusing to fault at the minute. The ground is ECU controlled and the 12v power is shared at a 5amp fuse with the clutch switch and reverse switch. It is possible I have disturbed the fault by moving the wiring but I ha...

Having only autodata to use in the workshop I sometimes find that the info is lacking. Where do you guys find info on code setting criteria?

Hi all. Got a strange one at the min. Got a pug boxer with the 2.2 transit engine that's intermittently throwing a pending code for maf sensor high input. Watching live data pids. The maf is reading around 10 - 12 g/s at idle with EGR commanded in the low teens. Map also showing good figures. The fa...

I more than agree with that don't rate the scope at all

Scoping a petrol fuel injector current and I seem to be getting hash in my waveform which looks like coil firing events. Can someone explain why this happens? I also randomly get a large spike in the fuel current ramp... pic included. Current clamp connected at 15amp fuse.

Please be gentle I'm very new to all of this and have no mentor to guide me. I have a Chevy spark with a cylinder 2 misfire and rich code. I have played about with the scope in my spare time and need help on what I'm seeing. I will post a few pics. Please remember I am very novice at all this but wa...

Yes it has a DRV on the rail. Customer unfortunately has taken vehicle away as it's needed. I suspect a leak some where as scoping the pressure sensor the rise time has some small drops in as it builds pressure doesn't rise and hold but seems to drop slightly. Thanks for the info. Will see if the cu...

current ramping on pump seem to peak at around 8 amps. run again this morning and priming pressure built up to 75psi the second the key was in the crank position but I still got an extended crank.
