Hey guys - so I just ran the ECU in diagnostic mode and came back with 4 error codes - EVAP EGR VSS and KS -

I have replaced the KS and VSS so I don't know why those codes keep coming back... possibly a wire harness'??

VSS -
(Replaced)
I have also taken apart the gauge cluster and cleaned literally all of the contacts with electronics cleaner but that didn't seem to fix the VSS code.

KS -
(Replaced)
I have also cleaned the contact points between the KS and the block to no effect.

Regarding the EVAP and EGR - I'm just wondering where I should start first? what (if anything) is the general culprit for either the EVAP or the EGR? any help would be greatly appreciated.

 

You may need to replace the printed circuit board on the back of the cluster. I had both the original one and a junkyard one both go bad, causing a P0500. Of course it could also be a fault in the harness somewhere, or the speedometer assembly itself.

 

if u have replaced with new components then its hard to imagine they are faulty already. Where u get the parts from? Seems more like an electrical issue to me
