Hi,
My trucks check engine light, speedometer & tachometer, intermittetly go on and off. I had the codes scanned and these four came up: PO740A PO753A PO758A P1860
I've seached the web and purchased a Chilton's Manual but I can't seem to find any info on these codes. Does anyone know anything about these codes?
Thanks in Advance, Keith
I don't know what the A at the end is but right from the Chilton's:
So many electric problems I would look for a loose, corroded or broken off wire harness.
Check for a bad ground under or around the dash, or a bad connector on the back of the dash cluster.
