Walker 242-1445 Ignition Knock (Detonation) Sensor

Walker 242-1445 Knock Sensor Overview

Walker 242-1445 is a Sensor Only ignition knock sensor built as an OE replacement for gasoline engine management systems. It monitors engine vibration and sends the signal the ECU uses to adjust ignition timing when detonation is detected.

This Walker Products knock sensor is built to OE specifications for frequency range, sensitivity, and electrical output. It uses a spade terminal design with 1 oblong female connector, 2 male terminals, and an included wiring harness for factory-style connection.

Key Features

• OE replacement ignition knock (detonation) sensor
• Part number: 242-1445
• Spade terminal type with 2 terminals
• 1 oblong female connector
• Factory-style wiring harness included
• Heat- and oil-resistant construction for engine bay conditions
• Tuned for accurate knock detection and spark timing control

Product Details

Walker Sensor Only products focus on direct-fit sensor replacement for engine control systems. The 242-1445 knock sensor is engineered to match the resonant frequency and electrical output expected by the vehicle ECU, helping the system identify spark knock and respond with real-time ignition timing correction. That precision matters on applications such as the Hyundai Venue, Kia Rio, and Hyundai Accent, where accurate detonation feedback supports stable drivability and engine protection.

Compatible With 2020-2026 Hyundai Venue, N/A; 2020-2023 Kia Rio, N/A; and 2020-2022 Hyundai Accent, N/A. This part number, 242-1445, is a direct OE-style replacement for vehicles that use the listed sensor-only configuration.

What It Helps Resolve

• Knock sensor fault codes such as P0325 or P0330
• Ignition timing errors caused by inaccurate detonation feedback
• Engine pinging or spark knock under load
• Reduced fuel economy related to timing correction issues
• Drivability concerns tied to a failed knock sensor signal

Installation Notes

Install the sensor in the original threaded location and connect it using the factory-style terminal layout. Verify connector shape, terminal count, and harness routing before installation. Because knock sensors are tuned to engine-specific frequencies, confirm application match by year, make, and model before replacing the original unit.

Quality Assurance

Walker Products builds this sensor to OE replacement standards for fit, sensitivity, and electrical output. The Sensor Only line is focused on direct replacement components that restore proper engine control input without changing the vehicle’s original sensor strategy.
