Unfortunately, it"s a common occurrence for a Nissan knock sensor password to collection on few of the automakers most renowned engines and also model automobiles.

Although 10 various knock sensor password can set from P0325 through P0334 the most typical 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 passing state inspection.Besides that, the hit sensor is really an essential sensor for getting the preferably power and also fuel economy out of your engine. As soon as the sensor malfunctions, two usual complaints end up being a noticeable absence of performance and a significant decrease in miles every gallon.

One of the things that shock me is the far-reaching number the automobiles influenced by this Nissan knock sensor code. Any type of vehicle transferring the 3 l V-6 engines indigenous 1990 v 1999 will ultimately need this repair. The Nissan Pathfinder and also the Maxima are two automobiles that fit into this category.

In addition, part four-cylinder models carrying the 2.0 together I4 suffer these problems. Famous models choose the Sentra, Nissan 240SX and also Nissan Altima indigenous 1993 with 2001 make this list. Also some of the brand-new models through the reliable 2.4 L like the Nissan Frontier pickup and also the pursuit minivan aren’t freed from setting a Nissan hit sensor code. In this write-up will define why it"s worth her time to address the problem. Back I like to repair this vehicles the right method by removed the intake manifold and replacing the fail knock sensor there’s an alternative. Plus, you"ll uncover relocation kits, technical tips and also replacement parts that help you gain the project done.

Testing the knock Sensor before Replacing It

Maybe it"s no a fail knock sensor? I"m a huge believer in verifying failure components. Testing the punch sensor isn’t too difficult. With the key on, engine off you can earlier probe the eight pen connector top top the passenger next valve covering of a V-6 engine and find a recommendation voltage in the 4 V range.

The wire is the largest diameter white cable in the eight terminal connector. Friend can get a screwdriver and also tap on the block and look for changes in the voltage come verify that the punch sensor is working properly.

However, when faced with a Nissan knock sensor code in the P0325 with P0334 range I have never uncovered anything as well as a fail sensor. In fact, in many cases I uncover the sensor broken or cracked. Hence I don"t even bother experimentation them anymore, since I"ve never ever seen something else go wrong in the circuit.

Repair Procedure because that Nissan knock Sensor Code

Nissan knock Sensor Relocation Kit

Nissan supplies the exact same knock sensor ~ above the V-6 engines and the two varieties of four-cylinder engines discussed here.

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

Since the ar is short the easiest method to obtain to the is to raise the car and also approach the from the bottom. Using a 12 mm stubby box end wrench seems like the best strategy to eliminate the bolt.

Nevertheless, accessibility is restricted in this location. However, if there’s any an excellent news come share it"s this 12 mm bolt is not tightened down an extremely hard and comes loosened easily. In fact, ~ you cracked the bolt loose you can spin it out v your fingertips.Replacing this exact same knock sensor part on the 3 L and 3.3 together Nissan V-6 engines is a whole different animal. They mount the hit sensor in the lifter valley of the block on this engines. The Chevrolet V8 punch sensors room in the same location and additionally fail.

The only means to gain at the is to remove the plenum and the entry manifold. We take into consideration this a difficult repair also for skilled technicians. In the next section we’ll talk about using a relocation kit to avoid having to pull the engine apart.

How come Relocate a Nissan knock Sensor

Even though replacing the part on the four-cylinder engine isn’t simple it"s the finest option top top the four-cylinder engines. However, top top the V-6 models you do have actually an alternative of relocating the sensor come avoid having actually to traction the engine apart.What you perform is relocate the punch sensor to among the plenum bolts. Once you perform this, you cut the initial harness and splice in a instead of pigtail the attaches come the new location. Here’s the reason I don"t like it. The knock sensor doesn"t pull in a strong input like it does once it"s attached come the engine block.

To me the punch sensor remains a an extremely important component. It enables the engine control module to carry out maximum ignition timing development until that hears an engine ping. Once detected it then slightly backs off the timing.

Changing the design and also how the circuit operates doesn"t seem choose a an excellent idea to me. Through that said, I have seen civilization go with the relocation procedure and also I haven"t heard of any type of problems yet.

I don"t blame you for wanting to take it the simple route. And also maybe this is the right thing for your situation. Because that one thing, these old rides are getting towards the finish of your life span. World just desire them to pass state emissions inspection without dumping a many money into a vehicle that won"t last much longer. If you loss in this group than the choice seems clear.
