No you don't have to change the harness unless it is cracked, broken, or have burn marks.

    Knock sensors, according to Nissan, almost NEVER need to be replaced. Most of the time your sensor is picking up vibrations from other parts of the vehicle, causing a fault. Check tires for proper balancing, drive line, front end, etc.

Need to know how to install knock sensors and where they are need diagram. 2005 expedition 5.4 engine


Hello adamjerkins,

It is somewhat complicated to change the knock sensors. There are two of them and they are located under the intake manifold. The intake manifold must be removed. I would recommend tha you replace both while you have the engine apart.

What leads you to believe the knock sensors are bad, I've seen few bad knock sensors? The knock sensor issues more times than not have been caused by other problems.

After you remove the intake manifold disconnect the knock sensor connectors. Remove the bolts and the two knock sensors then replace with new knock sensors tighten the bolts to 15 foot pounds. Reinstall manifold. The total job for an experienced mechanic with tools is about 5 hours. Not a good job for a beginner.

oil pump is in the oil pan and if you have no or low oil pressure replace pump before doing anything with knock sensor. knock sensor is more or less a microphone and listens for spark knock but will set codes for any knocking or tapping noise which is commonly heard if oil pump is malfunctioning

knock sensors are not worth replacing. Most of the time the knock sensor is just reacting to somthing else causing it to react.
