1989 Nissan Maxima Knock Sensor


  • 7532

The knock sensor in your Nissan is a vital part of how your ECU controls the engine and delivery of the fuel. Over time and repeated heat cycles, parts of your engine may deteriorate, like the fuel injectors, Mass Air Flow Sensor or Oxygen Sensor. When these parts of your Nissan begin to fail, it can make your Maxima run "lean" or with less fuel in your engine. This is irregular ignition and can cause serious damage to your Nissan.

An overly lean condition can cause your engine to run lean, or "knock", this is known as pre-ignition and it can be caused from several different sources. Your Nissan knock sensor prevents your engine from becoming damaged due to this knock, and you can usually hear it as faint rattling or "pinging" in your Maxima.

This sensor is basically a simple piezoelectric element that detects engine knocking or preignition and translates this vibration into voltage. The ECU reads this voltage and takes the appropriate action, either by curbing or decreasing ignition or increasing fuel.

The Infiniti or Nissan OE part number for this knock sensor is 22060-2A000, although the same knock sensor can be sourced from a turbo Volvo. The Volvo part number is 13676440.
