What is a Wiring Harness for Knock Sensor?

• The Wiring Harness for Knock Sensor​​​​​​​ connects the knock sensors to the vehicle's ECU. It ensures accurate signal transmission from the sensors, allowing the ECU to monitor and respond to engine knock in real time. A degraded or damaged harness can interrupt this signal, leading to poor ignition timing, reduced fuel efficiency, and engine performance issues.

 

What happens if the Knock Sensor Harness fails?

A faulty wiring harness can mimic sensor failure, causing:

• Check Engine Light (CEL) to appear
• Poor engine performance or misfires
• Increased fuel consumption
• Failure to detect and control engine knock
• Replacing a damaged harness restores proper signal flow and helps maintain optimal engine operation.
