Walker 242-1361 Ignition Knock (Detonation) Sensor
Ignition Knock Sensor for OE Replacement
Walker 242-1361 is a Sensor Only ignition knock sensor built for OE-style replacement on select 2002 Chevrolet Trailblazer, Trailblazer EXT, GMC Envoy, GMC Envoy XL, and Oldsmobile Bravada applications. It monitors engine vibration and sends the signal the ECU uses to adjust ignition timing when knock is detected.
Key Features
- OE replacement knock sensor tuned for the correct resonant frequency and electrical output
- Pin terminal design with 1 female connector, 2 male terminals, and an oblong connector shape
- Heat- and oil-resistant construction for engine block and cylinder head environments
- Direct-fit replacement for factory threaded sensor locations
- Supports accurate spark retard control when detonation is detected
Product Details
Walker Sensor Only line focuses on direct replacement sensors that match factory specifications for fit and signal behavior. Part number 242-1361 is engineered for precise knock detection on the listed 2002 GM and Oldsmobile platforms, helping the engine control system respond quickly to spark knock and detonation events. This part cross-references AC Delco (e.g., 213-352, 213-353) for the same application.
What It Helps Address
- Knock sensor fault codes such as P0325 or P0330
- Audible spark knock or detonation under load
- Incorrect ignition timing response from a failed sensor signal
- Reduced fuel economy caused by improper timing correction
- Drivability concerns related to engine knock detection
Installation Notes
Fits 2002 Chevrolet Trailblazer, N/A. Fits 2002 Chevrolet Trailblazer EXT, N/A. Fits 2002 GMC Envoy, N/A. Fits 2002 GMC Envoy XL, N/A. Fits 2002 Oldsmobile Bravada, N/A.
