My truck seems to randomly shoot off "check gauges" at will. Seemingly for no reason or any specific time. My wife typically drives the truck locally and it shows when she's stopped or under about 40mph. Any ideas? Battery is brand new and fluids are good.

 

Side not. Coolant flush about 2 months ago, oil change last week. Power steering and brake fluids are topped off. Ran truck up to temperature and it's reddish but still within range.

 

Is the CEL flashing? If so, that indicates misfires. How old are the plugs, etc? Any codes?

 

My man.... no codes. I've ran checks multiple times. It " looks" like CEL flashes once in Aux power just before startup but never CEL light. Guages are all in normal range.

 

Ok, that's just weird......

Maybe a bad connection somewhere? If you hit bump, does it matter??

 

No, my wife drives the truck to take kids to school. 1.5mi round trip. Once she told me about the gages I brought the truck up the temperature ran it around our neighborhood for a while down a steep hill and stopped and then up a steep hill and stopped and then drove it back around parked and checked the transmission fluid and everything seemed fine. No flashing gages.

You recently helped me with my 02 sensors and my spark plug issue. I thank you again sir

 

Prior to this and the fixes you helped us with. We got the vehicle smogged and we got the tags paid for. It ran just fine for about a month and now we're getting these gages. Trucks this period truck still runs just fine fine but it is Causing a little worry.

 

Wonder if the short drive distance is annoying the computer..... mile and a half? The engine doesn't even get warm......

Have her track when the lite goes on, how long it stays on, what is happening at the moment, and if anything changes in how the truck drives, or shifts.....

 

She'll drive it 60 miles at most, but few and far in-between. She says typically at idle or under about 40mph. From what I gathered it's either battery (which is new), or fuel sensor. I just thought I'd run it past you all here first.
