#3520 of 3636 Impala low oil pressure warning goes off
Oct 03, 2009 (5:53 am)
On my 2006 Impala, when I accelerate, the low oil pressure warning goes on. Even if I am just speeding up 5-10 mph. Once I reach my higher speed and stop accelerating it stops (so far). It seems worse after the car is more warmed up. I had a new switch installed but that did not cure it. Oil is clean, level fine etc. Neither the Chevy dealer nor my very good mechanic can figure it out. Anyone know anything about this or have any ideas?

Has anyone ever got there "low oil pressure warning - turn engine off immediately" problem solved. My local Chevy dealer prior to my spending big bucks says it most likely is a computer cluster issue or possibly an oil pump that is starting to fail. Most annoying is the darn warning chime. Please let me know. Thx

I finally got mine fixed. It was the sensor, often called a "switch" that senses the oil pressure. It turns out in my case there was not low oil pressure, just a false signal from the bad sensor.
But one cannot take a chance. If the sensor is acting properly, and pressure is low, it could really damage your engine to have low oil pressure and oil not pumping up to the valves.

How much did it cost to get this sensor replaced?

The sensor was $65 bought from the dealer as no parts stores have it yet without special ordering. The labor was $35. I have a good mechanic that does give me a great price as i have 5 boys so we keep him busy.

That is a great news. I thought it would be alot more than that. What is the "official" name of the sensor? Also, do you have the part number off of the receipt from the dealer? I have to watch my money as I just started working again since being laid off in January.

We have a 2006 Impala and are having problems with all windows in the car fog over when the heat is on. It has gradually gotten worse. At first as long as it was on defrost it was not as bad, now it doesn't matter what setting it is on. Dealer says it is NOT the heater core but is possibly an HVAC filter that is clogged. They want to charge $120.00 to see if this is the problem. Does anyone have any suggestions before we spend this and find it is not the problem?

Changing the HVAC (cabin) filter in an '06 Impala takes less than 15 minutes. The filter can be purchased for less than $15 at Walmart or Advance Auto Parts/Autozone/Pep Boys. A dealer charging $120 to change this filter should be ashamed of themselves. ~$50 would be more reasonable (accounting for the cost of the filter plus their labor.)
I really don't see how the cabin filter could be the problem, unless yours is so clogged that it is restricting airflow to all the vents. Have you noticed a significant reduction in the flow of air coming out of the vents?
How many miles on your Impala? When was the last time you changed the cabin filter? I put a new one in mine at about the 30K mile mark, and still have that one in now at 50K miles. I did remove it a couple of months ago and vacuum it out, but put it back in. I might put in a brand new one come Spring...eventually.

Thanks for your reply. We really didn't think it could be the HVAC filter but it would not hurt for us to change it. However, we will change it ourselves if its not that hard. I am calling Autozone today to see about getting the filter and changing it ourselves. Our Impala has 40k miles. We'll be posting again to let everyone know what the real problem is and if changing the filter fixed it.
