2004 Chevrolet Tahoe P0332: Engine Stalls After Long Drive - Knock Sensor Issue

Model: 2004 Tahoe Fault Code: P0332 Posted: 2017-06-30 11:25

I own a 2004 Chevrolet Tahoe that is throwing a P0332 diagnostic trouble code. This code indicates a faulty knock sensor, which is responsible for detecting engine knocking and adjusting ignition timing accordingly. I've noticed the engine will occasionally stall or lose power while driving, especially after being on the road for about one hour. After shutting off the engine for a few minutes, it typically restarts and runs normally until the next occurrence. The pattern seems consistent: the issue happens only after extended driving periods. I'm concerned whether a faulty knock sensor or related issues can cause such intermittent stalling or loss of power. Any insights on this behavior would be greatly appreciated.

Could you confirm which engine variant your Tahoe has? The 8th character in the VIN will identify whether it's a V6 or V8. Additionally, please provide all active diagnostic codes — not just P0332. Note that P0332 is indeed a knock sensor-related code, but some sources suggest it may be misinterpreted or less common on certain 2004 Tahoe models. Double-check the code entry to ensure accuracy; sometimes typos occur in initial posts.

Apologies for the earlier typo — I meant to write P0332, not P0032. The correct code is indeed P0332.
