Engine service warning message

[Peterspencer]

Its appeared a few times now over a couple of months, i reset the codes do the start procedure and no new codes appear immediately so guess its something which appears after time or is intermittent.

The fault codes are all high or low signal

High signal no2 injector
Low signal Maf
Low signal,swirl thingy.

I guess either the ecu has an issue or was wondering if there could be a dodgy connector somewhere, is there a common fault to cause this?

I doubt its the ECU. I would trace the wiring and check power/ground/signal voltages.

VIDA will also give you suggestions as to posssible causes if you use it to read the codes. The generic code readers can be misleading.

Vida only points to the faulty ECU but as you say its quite odd as so many signals are an issue.
I will check earth connections ect at the ecu once i find it, to be fair not looked yet

I only asked for a bit of assistance, this is not assistance in any way shape or form and if this is the forum I guess i am best finding a new one.

You have had 2 prompt responses from long-term, experienced forum members. The advice you have been given is the best you will get, given that we have not got all the info required.

I don't know what else you can expect.
