The other day I got my volvo back from the mechanic. We thought it was the ECU at first but when he put the alternator belt on right and fixed the adjusting pin, the thing cranked right up ... so I drove it home. I went to drive to work last night, and go figure ... it doesn't crank. So I used to OBD and I got back this -

3-1-2: Signal Missing for Knock-Related fuel enrichment

Cause : Wiring break between EZK terminal and Fuel Injector #28.

I don't have a EZK in my Volvo. its the 2.4LH Turbo Intercooler.

So before I pay for ANOTHER tow to my mechanic, and I wanted to see if someone might have an idea for a quick fix.

Thanks MVS.

My list of fault codes shows 3-1-2 as signal missing but does not specify EZK.

Time to get out the ohm-meter and do some testing.
