Does any one know where I can find any information this code?? I have searched the 'net but can't find a definitive answer.
I know that this is not the proper forum for this (as it was on a Sierra), but I was (am again) an Envoy owner and i know there is a ton of ppl on here that are quite knowledgeable.
Details... I was driving a highway... all the sudden chiming started, i looked down at the instrument cluster, and is said "stop engine low oil pressure"... so i shut it off and pulled off the road, got out, looked underneath, nothing dripping, check the oil level and all was ok. At this point the Check engine soon light was not on. I started it back up and at idle had ~40 lbs of oil pressure. Sat for a second and took off again. Within a few minutes of driving (~60 mph), i could see the gauge begin to drop, and the Check Engine light came on. Drove about 10-20 miles and the chimes started again and the low oil message appeared. Pulled off again, and sat for a bit, luckily i had my ScanGauge II hooked up and found the code 'B2AAA'. Throughout this, I am out in the country and no cell service. Started back up and took off, few miles later, the same.
Finally, got it to a gas station and called the dealership. The dealership came (~50 miles away) and picked it up, and returned my Envoy. They told me they would check it out and let me know.
But at this point i am curious... and can't find any info.
