Walker 242-91094 Ignition Knock (Detonation) Sensor
Ignition Knock Sensor for OE-Style Engine Control
Walker 242-91094 is an OE replacement ignition knock sensor built to monitor engine vibration and report detonation events to the ECU. It helps the engine computer adjust ignition timing in real time, supporting smoother operation and helping protect internal engine components from spark knock.
Walker Products Full Service Kit line focuses on direct-fit replacement parts engineered to match factory specifications. This knock sensor is tuned for the correct frequency range, sensitivity, and electrical output for the application, with a factory-style circular connector and bullet terminal design.
Key Features
- OE replacement ignition knock (detonation) sensor
- Engine vibration monitoring for knock detection and timing correction
- Engineered to match OE frequency range, sensitivity, and electrical output
- Heat- and oil-resistant construction for engine-block and cylinder-head environments
- Direct-fit threaded mounting location with factory-style electrical connection
- Connector quantity: 1; connector shape: circle; connector gender: female
- Terminal quantity: 1; terminal type: bullet; terminal gender: male
- Wiring harness included: No
- Mounting hardware included: No
Detailed Description
Walker 242-91094 is designed for gasoline engine applications that rely on accurate knock detection to manage ignition timing. By sending a signal when detonation is detected, the sensor helps the ECU reduce spark advance and maintain proper combustion control. This is important for drivability, fuel economy, and engine protection. The Walker Products Full Service Kit line is built around OE-style fitment and electrical performance, making this sensor a direct replacement for the original unit on supported vehicles. This part cross-references Standard Ignition KS85 for the same application.
Compatible With 1995-2001 Honda Passport, N/A; 1999-2001 Isuzu VehiCROSS, N/A; 1996-1999 Acura SLX, N/A; 1998-1999 Isuzu Amigo, N/A; 1996-1999 Isuzu Rodeo, N/A; and 1995-1999 Isuzu Trooper, N/A. Walker 242-91094 is also a fitment-based search match for Honda Passport knock sensor replacement and Isuzu Rodeo knock sensor replacement applications.
Common Issues This Part Can Address
- Knock sensor fault codes such as P0325 or P0330
- Erratic ignition timing caused by inaccurate knock detection
- Spark knock or detonation under load
- Reduced drivability from a failed engine knock sensor
- Engine control issues related to damaged OE sensor output
Installation Notes and Tips
Install the sensor in the original threaded location and connect it using the factory-style terminal interface. Verify the connector shape, terminal type, and harness condition before installation. Because this part does not include mounting hardware or a wiring harness, reuse serviceable original components where applicable and inspect the mounting surface for corrosion or contamination.
Quality Assurance
Walker knock sensors are built as OE replacement components with application-specific tuning for frequency response and electrical output. The construction uses heat- and oil-resistant materials to withstand the engine environment and maintain stable sensor performance over time.
