At some point mine will have to come off to replace the driver's side valve cover gasket. When you cut into the cover and find the black-covered wire, the second wire is wrapped around the white wire inside the black cover and not separately insulated. The othe mechanic said I have two sensors that are out but will see if the O2 will correct the proble right so I can pass my emmissions inspection. When you cut it you will see a white wire and a silver coax wire wrapped around it. Sounds like they are searching for more money from an unsuspecting female. It's screwed into the engine block with a 12 metric bolt.
You might need to jack the rear end up to fit underneath the vehicle. Then you use a Allen style wrench to take off the bolts holding the manifold on. There is an unseen sensor behind the hatch panel which grounds to the mounting plate of the hatch lock assembly. If you have ever cut a cable wire you know exactly what I mean. Learn how to perform the reset procedure and replace the ignition lock cylinder. Test the theory by applying pressure to the outside of the hatch back lock.
The existence of this problem was discovered because the alarm system was going off during all hours of the day and night. You may also have a timing issue, that a tune up might fix. The one the guage uses is mounted on top of the intake manifold. With the key on, engine off you can back probe the eight pin connector on the passenger side valve cover of a V-6 engine and find a reference voltage in the 4 V range.

People just want them to pass state emissions inspection without dumping a lot of money into a car that won't last much longer. The engine sounds great, the check engine light went out, and I hope to get another 100,000 miles. The knock sensor is on the firewall side of the engine.
The code stands for knock sensor bank one sensor one circuit input high. I did a full 90k service, cap, rotor, wires, plugs, and knock sensor relocation. Nissan Pathfinder Knock Sensors function with a computer chip to check spark timing continuously so as to prevent engine ping, which might cause damage. Posted on May 13, 2011.

With that said, I have seen people go through the relocation procedure and I haven't heard of any problems yet. The only thing about his video that is not 100% clear is the location of the second wire. When detected it then slightly backs off the timing.
The guage sensor will not cause any driveability problems, it's only used to send a signal to the instrument panel on the dash. I have a 1999 Pathfinder that needs the knock sensor replacement. It detects cylinder knock incorrect detonation of the air-fuel mix and the engine computer adjusts timing and air-fuel ratio to compensate. Even back then, the relocation was pretty well established as a cheap fix for the problem. It is located under the intake manifold, bolted to the middle of the engine block. Just pay careful attention to the video, it definitely is a complete walk-through. The knock sensor on the 1996 Nissan quest is located on the right side of the engine block, under the top manifold.
This part is also sometimes called Nissan Pathfinder Engine Sensors. Has there been any noticeable improvement in fuel mileage? Be careful not to break the connector. Make sure you wire the new sensor to the live wire, not the dead, after the cut! It'll update as I go, but I've already driven about 70 miles and it's only just below the full line. Remove rear hatch panel -- Two plastic screw fasteners, the rest are simple panel pop rivots. The timing belt isn't that bad, take the rad out, remove the belts, pulleys, plastic cover, etc. It can be accessed from under the vehicle.
