I have a 2004 Ford Explorer sport track, the oil pressure gauge went to zero back 1 month ago, we changed the oil sending unit, no change. Any ideas on what next?


You need to get an actual pressure test on the block to get an actual reading, because I would hate for you to have lubrication problems in the engine and blow the engine. If the gauge is stuck on zero try with the engine off and key on, ground the sending unit wire to the block and see if the gauge pegs to full. If it does not, replace the gauge and get it calibrated if it needs calibrating.

If my 2004 chevy silverado oil pressure gage stays at 80 psi could this hurt the engine


I would want to know what the actual oil pressure is. The sending unit or the gauge on the dash could have failed.
There is a pressure relief valve to prevent oil pressure from going too high, but staying at 80psi would not be good for a long time.

Oil pressure gauge pegs at 80 PSI as soon as you turn the key on. I have replaced the gauge and confirmed the sending unit is working properly. Any ideas on where to look next?


Sounds like a grounded wire. Most senders change resistance to the ground circuit of the gauge. If it pegs there is no resistance to ground and probably a shorted wire.

Hello again, I had the oil changed this past Saturday drove for 700 miles and oil pressure stayed the same...80psi.....now the engine light has come on and the computer is showing that it still needs to be...


If the check engine light is on (and not flashing) simply take it to one of the various auto parts chain stores that offer free scanning. That will tell you why the light is on and might even lead to a repair.
As for oil pressure gauge. It could be a bad sending unit, bad gauge itself, or sometimes a broken wire. A competent mechanic will have a mechanical oil pressure gauge to verify what the real reading is.
The check engine light and oil pressure gauge reading may or may not be related.

Oil gauge reads 80psi what is the problem


Sounds like a faulty sending unit. Remove transducer (sending unit) and test pressure with external gauge. Hope this helps.

Changed oil in my jeep grand cherokee 1999 v6,and noticed the oil pressure gage is now setting at 80psi,and the filter is correct.


Not sure about your car, but alot of times the oil gauge sending unit is kinda close to the oil filter, and maybe during the oil change the wire connection was removed or damaged. Turn the key on and engine off ,and if the gauge reads 80psi then the sneding unit might be the problem
