Just got the car and was driving down the road all of the sudden the dash starts chiming and telling me the oil pressure is low. I stopped and checked the oil and it looked fine. I started the car again and it didn't say anything so I started driving again. About 45 minutes later the exact same thing happened again. So I did the same thing and drove another 45 minutes until it happened again. I haven't fixed anything yet but I will start with the oil pressure sensor.
The engine light was on and the car seemed to be running fine. That is when i went in to hook it up to the diagnostic machine. We found out it was the oil pressure sensor. You do have to order the part through GM, but it is only $10.00. my husband fixed it in about 10 min.
Oil sensor light comes on or stays on.From time to time, it tells me that my engine is hot, turn off A/C and the engine's fan pops on. I have checked my oil & water, but everything is fine. Not fixed because I do not have a clue of where I should go. I feel as if GM will overcharge me.
Was driving and the no oil pressure warning came on. Checked oil. It was ok but added just a dash. Drove about 45 min and it did it again. Checked oil then was able to drive the 2.5 hours home without issue.
I have the same problem and I know what the fix is but I would like to know how many of you guys that have this issue also had the bad power steering line recall on their Impala as well because that sensor could be going bad based off of all the fluid being Splashed onto the sensor before it was fixed very hard to clean it all off. Just a little food for thought the sensor is right by where that line goes bad
I have taken my 07 chevy in for oil filter housing unit to be replaced and less than 24 hrs of getting car back the engine light is on. Technician tells me that oil pressure sensor looks like it went out due to sensor are very sensitive on gm model cars.
Car running normal. Check Engine light on, not gas cap or fuel type. Also not going into 3 cyl mode. After a lot of internet research and codes ran by mechanics advised to change oil pressure sensor, I bought one and will install very soon. I had car only three weeks so this was a scary scenario but I am confident that is the problem and will be able to fix for $30 if I install myself.
