Knock Sensors 1, 2 Chevrolet Impala 2.5 2014-2020 Location and Replacement

In this video, I show you only the exact location of both Knock Sensor 1 and Knock Sensor 2 on a 2014-2020 Chevrolet Impala 2.5L.

Knowing the precise spot where these sensors are threaded into the engine block will save you time and take away the guesswork if you are tackling a DIY repair.

Common Symptoms of a Bad Knock Sensor:

• The check engine light comes on (frequently with codes like P0324, P0325, P0327, P0328, P0332, or P0333)
• A noticeable metallic pinging, knocking, or rattling sound from the engine under load
• Poor acceleration, sluggish throttle response, or a general loss of engine power
• Decreased fuel economy as the engine computer alters ignition timing to protect the motor
• Rough idling or engine hesitation

Safety First

Always put safety first before reaching into tight spots under the hood. Make sure the vehicle is safely parked on a flat surface, the engine is completely turned off, and it has had plenty of time to cool down to avoid severe burns. Protect yourself by wearing safety glasses and heavy-duty work gloves, and always stay fully focused on what you are doing.
