How can i relocate the knock senser without pulling the suppercharger and intake the scanner sayes i have a bad senser. i am lossing power when accelerating.i have allready replaced plus cap distibutor andsupercharger soilonoid valve. please help me. robert lewis

the knock sensor is in the block under the manifold if its a v6 it is under the manifold between the cyl heads may have to take intake manifold off to find it

P0201 Cylinder 1 Injector Circuit Malfunction

Sounds like you missed connecting something back up. The Knock senser won't make it not run it'll just not let it run at peak power. The OHMs on the sensers just need to be close and your old senser may be just fine. The senser watches a reluctor wheel go by. Did you put it back on? did you put it right side up? It'll fit backwards but it won't line up with the senser.

• Leakage in Intake and/or Exhaust System
• Catalyst faulty
• Oxygen Sensor(s) faulty
• Oxygen Sensor(s) Control faulty

Possible Solutions

• Check Intake and Exhaust System for Leaks
• Check Catalyst
• Check Oxygen Sensor(s)
• Check Oxygen Sensor(s) Control

It's located deep in the valley! Under the "LOWER intake manifold". copy and paste this link in your browser, or try clicking on it. It may be helpful to you.

I didn't find this link until after I had already disassembled my truck. This is the hardest job that I've taken on thus far, hope I can put it all back together properly. I changed the gaskets on the valve covers since I had everything off.
To answer your question: It's under your lower intake manifold, so it's a hard job!

Is your "check engine" or "service engine soon" light on? Lacking power is usually an emission system problem, for instance possibly a bad EGR valve or mass air flow senser. O2 sensers are common to fault but normally doesn't cause power loss usually causes alittle rough idle. Could even be a pluged catalic converter to. have the truck plugged into a scanner, that will tell you the trouble codes and fault info.

Hi, my 01 Mill. noc senser was on top of the motor, but under the intake! needless to say it cost alot... had other stuff done so I can't tell what cost was ($1800 total)

sounds like you have a blown head gasket this would explain loss of coolant and running poorly excessive smoke.

For replace the knock sensor on a maxima.
You need to remove the intake manifold.
If not, you have no access to the sensor.
This prosses require about 3.5 hour labor.
