Although 10 various knock sensor codes can set from P0325 with P0334 the most usual code you"ll uncover is the P0328. The code represents knock sensor financial institution one sensor one circuit input high. Countless would favor to overlook this code, but ultimately it deserve to stop girlfriend from pass state inspection.Besides that, the hit sensor is really an important sensor for getting the preferably power and fuel economic situation out of your engine. As soon as the sensor malfunctions, two typical complaints end up being a noticeable lack of performance and a significant decrease in miles every gallon.

The Nissan Pathfinder and also the Maxima space two automobiles the fit right into this category.

In addition, some four-cylinder models delivering the 2.0 l I4 endure these problems. Famous models prefer the Sentra, Nissan 240SX and also Nissan Altima indigenous 1993 through 2001 do this list.

Return I favor to repair this vehicles the right method by removing the input manifold and also replacing the failed knock sensor there’s an alternative. Plus, you"ll find relocation kits, technological tips and also replacement parts that assist you acquire the project done.

Testing the hit Sensor before Replacing It

Maybe it"s no a failure knock sensor? I"m a large believer in verifying failure components. Testing the knock sensor isn’t too difficult. V the an essential on, engine off you can earlier probe the eight pen connector on the passenger side valve cover of a V-6 engine and find a recommendation voltage in the 4 V range.

The wire is the biggest diameter white wire in the eight terminal connector. You can get a screwdriver and also tap on the block and look for alters in the voltage to verify the the hit sensor is functioning properly.

However, when challenged with a Nissan punch sensor code in the P0325 through P0334 range I have never found anything besides a fail sensor. In fact, in many instances I uncover the sensor broken or cracked. Therefore I don"t even bother testing them anymore, due to the fact that I"ve never ever seen noþeles else walk wrong in the circuit.

Nissan knock Sensor Relocation Kit

Nissan provides the exact same knock sensor on the V-6 engines and the two arrays of four-cylinder engines pointed out here.

Surprisingly even the four-cylinder fix procedure isn"t the easy, since of the hidden location that the part. Top top the 2 L and also 2.4 together engines, they download the knock sensor on the block in between the firewall and also the engine. That leaves small room for hands and tools.

Since the place is low the easiest way to get to the is to raise the car and approach that from the bottom. Utilizing a 12 mm stubby box finish wrench seems choose the best strategy to remove the bolt.

Nevertheless, access is minimal in this location. However, if yes sir any good news come share it"s this 12 mm bolt is no tightened down very hard and also comes loosened easily. In fact, after you cracked the bolt loose you can spin the out v your fingertips.Replacing this very same knock sensor component on the 3 L and also 3.3 l Nissan V-6 engines is a whole different animal. They mountain the hit sensor in the lifter sink of the block on these engines. The Chevrolet V8 knock sensors room in the same location and likewise fail.

The only method to gain at that is to remove the plenum and the input manifold. We consider this a daunting repair even for knowledgeable technicians. In the next section fine talk around using a relocation kit come avoid having actually to pull the engine apart.

However, top top the V-6 models girlfriend do have an option of relocating the sensor come avoid having actually to traction the engine apart.What you perform is relocate the punch sensor to one of the plenum bolts. As soon as you do this, you cut the initial harness and splice in a replacement pigtail that attaches come the brand-new location. This is the factor I don"t choose it. The knock sensor doesn"t pull in a solid input favor it does as soon as it"s attached to the engine block.

To me the knock sensor continues to be a really important component. It permits the engine regulate module to carry out maximum ignition timing advancement until the hears one engine ping. When detected it climate slightly backs off the timing.

Changing the design and how the circuit operates doesn"t seem choose a great idea come me. Through that said, I have seen civilization go through the relocation procedure and also I haven"t heard of any kind of problems yet.

I don"t reference you for wanting to take the straightforward route. And also maybe this is the ideal thing for your situation.
