#1 of 6 Impala low oil pressure warning goes off by softshellcrab 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?

Replying to: softshellcrab (Oct 03, 2009 5:53 am) 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 Replies to this message: softshellcrab (Oct 26, 2009 8:41 pm) nachoesp (Oct 27, 2009 7:47 am)

Replying to: bbaby1 (Oct 26, 2009 7:28 pm) 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.

Replying to: softshellcrab (Oct 26, 2009 8:41 pm) How much did it cost to get this sensor replaced?
#5 of 6 Sensor cost by bbaby1 Oct 27, 2009 (4:18 pm)
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. Replies to this message: nachoesp (Oct 28, 2009 6:36 am)

Replying to: bbaby1 (Oct 27, 2009 4:18 pm) WOW! 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. Thanks! nachoespaol.com
