Oil Pressure Gauge - Always sits at 65%


GP1138

Recommended Posts

So the engine in my car has been replaced... is there a possibility that they could have gotten the engine from a car with no oil PSI gauge? My pressure gauge always sits in one place. I was revving it the other day and noticed it didn't move at all. Temp gauge works fine, doesn't read one single reading.

 

How hard is the sender/sensor to replace?

You can see in this video, it doesn't appear to move. The engine was plenty warm, too.

John, you have the standard gauge that uses an oil pressure switch. It's normal for it to sit in that area and stay there all the time.

 

Ah, I wasn't sure there. I didn't know the GPs had that as well.

I don't know about GPs, but the Cutlass didn't go to switch-only until '93. '92 cluster should read. I know my TGP clusters have/had working ones. I'm placing money on a switch being in the new motor rather than a sender.

Only the 1992 3.4 Cutlass and some 1992 3.1 Cutlasses (Internationals perhaps) received the sending unit with numbered gauge. All other 1992s had either the base cluster or H-L "gauge." Until I am proven wrong. lol

 

Okay...After a little research, it seems early 1992 CSs (below VIN 320,000?) and all 1992 3.4s had a numbered working gauge.

You're saying I have a dummy gauge?? :lol: Just seems silly to me. Thanks though.

john, and ev eryone else....

 

my 92 vert HAD a dummy guage. It works now, because the swapped in motor came from a car that had a working oil gauge, along with that car's wiring harness.

 

try grabbing and swapping it the long type oil sender, that may fix the problem.... although I have never found a resistor. if the resistor exists, you may not read full scale but at least is will still fluctuate.

 

lemme check something. I'll get back on it.

Yep. I have the same dummy gauge in my '93 SE. If I think about it, I'll compare the wiring between the two different types of gauges sometime soon...

The 1992 FSM doesn't show a resistor...

My '92 SL has the 'Gages' (full analog gauges) cluster, with all working gauges, not dummies. I have no idea what the VIN is off hand.

man you have the same car as me... go to your local parts store and ask for an ops switch for a 1992 gp se with the gauage not the dummy light because in 92 the 2 doors and the 4 doors had different dash setups. you do that then its all good and the sender is right beside the oil filter on these engines. if you need anymore help pm me
