I have a 1992 Pontiac Grand Prix with just 40,000 miles. Recently the "Check
Gauges" warning light started coming on when the car was started after
sitting a while, then turned off after it was warmed up. However, now it
seems to just stay on all of the time.
Note: It has a full set of gauges and all of them appear to be normal!
I have connected an "Auto-Xray XP240 diagnostic scanner to it, but NO
trouble codes were found. I think this is a common problem on this vehicle,
so I would appreciate hearing some possible causes for this problem.
thanks in advance,
