It worked fine before, but this is a new sender it seems as if it is working but oil pressure reads low it keeps telling me to check guages even if its not in the red.

if your wiring is all good and grounds hooked up and your dash was working ok before . you could have a bad sender even though its a new one. i will look on gm at work today for your car to see if there was any */b on it

What year, make and model of vehicle is this new sensor for? If you picked up one for something other than your car'* year, it may have different resistance.

Ok thanks 99 BonnevilleGreen. BillBoost 37, my car is a 96 Bonnieville SE, my motor is from a 98 Monte Carlo, the sensor I bought is from a 96 Bonneville SE.

I was hoping you had the wrong one.

Your best suggestion is to have the pressure checked with a mechanical oil pressure gauge. The motor may have issues that haven't become obvious yet and are showing up as low pressure.

talk to a tech at work today he said to try unhooking the battery for a few minute'* then hook it back up to see if that clears it up. still do like billboost said to.

Here'* the update, changed oil pressure sending unit. Now check guages light comes on even when gauges read normal? Any suggestions?

What did the mechanical gauge say?

I have to get one, trying to do that today. Where is the best place to buy one? Do I just buy the after market oil pressure guage?

I would probably have a mechanic check it f you don't own the gauge.
