I have a 1997 K1500 pickup and both my rpm and mph gauges are not reading correctly. They are both reading higher than the actual rpm/mph, and seem to get farther off as rpm or speed increases. Has anyone had this issue? Any help or troubleshooting advice would be greatly appreciated.
Rpm is 500-1500rpm off and mph is 5-15mph off. I have verified this by using scan tools and/or a gps speedometer. Mph and rpm are correct in the scan, so im thinking the pcm is sending the correct signal to the instrument cluster. I have tried 3 different instrument clusters and they all are off by the same amount. Please help!
