    P0332 Knock sensors code back....

    About 6 months ago i replaced the knock sensors and harnesses in my '06 Tahoe. This cleared the code and the truck has been running fine. Actually it ran fine before the replacement, but i wanted to clear the CEL. Well, the CEL popped again and it's the same P0332 Knock Sensor 2 Circuit Low...

    Is my charging system working right?

    2006 Tahoe, 200k miles. I'm a little over halfway thru a a long road trip - Alaska to Michigan, about 4500 miles. I look at the voltmeter and most of the time it's a needle width above the "14" - this is the normal reading. Several times a day i'll notice the meter is indicating about 2...

    OK, what is this and what does it do?

    2006 Tahoe. This little button is in the roof of the truck above the rear seat. It's making a noise like a fan motor and I can't seem to control it... so what is it and what does it do? Thanks!

    School me on knock sensors

    2006 Tahoe, 5.3, ~200,000 miles. A couple of months ago the CEL came on and the code told me knock sensors. I used a Torque Pro and my smart phone to get the code. Cleared the code and it came back about a week later. The truck runs fine, good gas mileage, no weird noises. I've probably put...

    Help me troubleshoot a vibration

    2006 Tahoe, LT, ~200,000 miles. I get a high frequency vibration, like a buzz, right at 50 mph. I can feel it and hear it. It's like I'm driving on a road that has a slight corduroy surface. It's subtle, but I don't think these things get better with age and I'd like to track it down now...

    TPMS questions

    I have an '06 Tahoe LT. About 8 months ago I purchased a set of nice wheels that came off a 2014 Silverado - a Craigslist find. About a month ago the "Check Tire Pressure" message came up on the DIC as well as the Tire Pressure warning light on the dash. All tires have appropriate pressure...

    Heater being weird - thoughts?

    So the outdoor temps are going down and i've started using the heater. The heater blows ice cold air for probably 10 minutes or more after the engine has come up to operating temp. It then will blow heated air as it should. The Tahoe is an LT and i have the climate controls set at 75 degrees...
