Took my 01 V6 in today for an oil change, and on the way home, the DIC is constantly showing pressure of 130 psi. Don't know how long it has been doing it, or, did the guy at Valvoline forget to hook a sensor back up? I know it was working last week, but it reads 130 at start up, idle, and on the road. Any ideas  |

seems to be a very common problem. It's most likely a bad oil pressure sending unit.

I'm going to check the connector first. I'm not the most mechanically inclined person, so if the connecter is unplugged, does the unit have to be replaced??

Well,the connector is plugged in, so, I guess my next question is, how soon do I have to get this replaced?  Any help is appreciated... |

Oil sending unit, had the same problem, a DIY fix. The sending unit cost quite a bit (dont remember except that it was not cheap) so I ended up leaving it alone.

It happened exactly right after an oil change? I guess if it were me, I'd be suspicious of what they put in there...

Bob, thats what I thought. Took it back to Valvoline, went under the car with them. Everything looked in order, sensor was plugged in, filter tight etc. The sending unit is inside the oil pan, correct? I guess my question is, is it ok to drive the car? I have had no experience with an oil sending unit. |

Auroralover - had the same problem with my 2001. As I'm so anal with my baby, had the oil changed ASAP and that didn't correect the problem. Due to circumstances, took it to the Olds dealer and had them check it out. Didn't want to drive with the pressure so high. Had the dealer replace the sending unit. $180.00 (ouch!!!). Wish I had the wherewithall to do more on this car myself. If you can replace the unit yourself, do it. It's gotta be a lot cheaper than having the dealer or a service center do it for you.

Since I bought the car originally it's had this problem - 130/131psi. Well, other than the engine throwing a rod one night about 8,000 miles ago (been fine since), nothing wrong has happened. Looks like it's a very very common problem with the 2nd gens... just a sensor thing.

The engine THREW A ROD and it's fine? You're joking right?

well yeah, got the engine (and things the rod went through) replaced - then those things replaced again - and it's been fine since  Yeah I meant it as a joke. I'm sure it was completely unrelated but I like playing with people's "AHH!" reaction.. I'm sure the car had the bad sensor for many tens of thousands of miles prior. |

Maybe I'm anal, but I wouldn't live with that problem very long. With the cost of repair/replacement of these motors, it's crazy to not know what you're engine is doing.
It would be like going to the doctor to have him/her look check your blood pressure and being told our machine is broke, don't worry about your heart.

GlennS87 instruments like the oil pressure readout while nice have little real life functionality. Oil pressure monitoring might be valid for automotive sports and mission critical applications. Im quite certain that most folks who own Auroras don't even know the oil pressure readout is there or what it means. Same goes for the rpm guage - what real purpose does it serve on an automatic transmission car? I understand what point you're trying to make by using the doctor analogy but surely you can tell when you're running a fever without a doctor's help. Likewise one does not need a guage to detect a critical loss of oil pressure or relative rpm of an engine. Lately I try to take it easy, perhaps you too should relax a bit and enjoy the ride |

When the oil pressure reads 131 that means the oil pressure sending unit is bad. 131 is the equivalent of "pegged" in the digital world of Aurora oil pressure. It is a $50.00 part with shipping from www.trademotion.com/partlocator/index.cfm?siteid=213768 and takes about 45 minutes to change. My sending unit went bad a couple of years ago and then last month started leaking, so I replaced it. It is accessed from under the car. Jack the car up and start at the oil filter cap. Go backwards from there, around the backside of the oil pan and up the back surface of the engine about ten inches. If you aren't sure if you have the right thing, unplug and start the engine. The low oil pressure warning should be on. If not, you unplugged something else. I was able to get a crescent wrench on it, unscrew it, and screw the new one in. Now I read about 70 psi at cold start idle and 10 psi warm idle. No leaking either! |

Your oil leaked beacuse of a sending unit? What do they have to do with each other?

The oil was leaking right through the guts of the sending unit. The sending unit screws into a hole in the back of the engine block where there is pressurized oil behind that hole. If you were to remove the sending unit and turn the engine on, oil would squirt out of the hole like crazy. When the engine was on, oil would leak from around where the wires plugged into the top of the sending unit. It came out at a reasonable pace as well. Probably 2 drops per second. My guess is that some seal in the sending unit broke a while back causing the unit to fail and start reading 131 psi at all times. After a while longer the failure got worse leading to oil leaking on my garage floor.

That's why it's called a sending unit. It sends oil onto the floor.
I couldn't resist. I have a problem.

So basically...The oil pressure isn't exactly 130psi but its just the sending unit mis read? Or is the pressure actually 130psi?
