Knock sensor Chevrolet Trax 1.4L 2013-2022 Location

In this video, I show you only the exact location of the knock sensor on a 2013-2022 Chevrolet Trax 1.4L.

Knowing the precise spot where this sensor is threaded into the engine block will save you time and eliminate the guesswork when planning your DIY diagnostic or replacement.

Common Symptoms of a Bad Knock Sensor:

• The check engine light comes on, frequently flagging diagnostic trouble codes like P0325 or P0327
• Loud metallic pinging, rattling, or knocking noises coming from the engine under acceleration (engine knock)
• A noticeable reduction in engine power, acceleration, and throttle responsiveness
• Poor fuel economy as the engine control module alters timing to protect the engine
• Erratic engine behavior or stumbling when climbing hills or carrying heavy loads

Safety First

Always prioritize safety before starting your repair. Make sure the vehicle is safely parked on a flat, level surface, the emergency brake is securely engaged, and the engine is completely turned off. Allow the engine compartment plenty of time to cool down fully to avoid painful burns from hot engine components. Because you are working near vital engine sensors and electrical systems, consider disconnecting the negative battery terminal to prevent electrical shorts. Protect your eyes and hands by wearing safety glasses and durable work gloves, and maintain your full focus throughout the task.
