Tricky Part 1: Separating the… This is a very easy task , with a little pacience. You can get a screwdriver and tap on the block and look for changes in the voltage to verify that the knock sensor is working properly. What you do is relocate the knock sensor to one of the plenum bolts. In fact, after you crack the bolt loose you can spin it out with your fingertips. Sorry it's a little out of focus, but the words look the same except for the Nissan logo on it 180° from the harness plug.
Using a 12 mm stubby box end wrench seems like the best strategy to remove the bolt. Seems like it can be 10 other things. Good quality and cheap price just the way I like. For those not familiar with this, the knock sensor is located under the intake plenums on the back side of the engine. I've read there is a battery memory saving device that goes into the power outlet to retain radio, navigation memory while the battery is being changed. This replacement Engine Knock Detonation Sensor is just what you need to get your vehicle in good running order again! Disconnect the wiring harness connector from the knock sensor by lifting the locking tab slightly and then pulling the connector off the sensor.
Ill be closely watching this thread as well. If the knock sensor is malfunctioning, this can lead to both poor fuel efficiency and major engine damage if not replaced immediately. AutoTrust Platinum provides a growing selection of low-priced switches, relays, and wiring components! Discard the old sensor and thread a new one in its place. Also, the part number he lists is for the wiring harness, not the knock sensor. The down stream is in the pipe just in front of the catalytic converter. You will need a special slotted socket which you can buy at most auto parts stores. However, when faced with a Nissan knock sensor code in the P0325 through P0334 range I have never found anything besides a failed sensor.
Changing the design and how the circuit operates doesn't seem like a good idea to me. Hi folks, Might i ask for a hand with my Quest woe? If engine knocking occurs, ignition timing will be suppressed to prevent it. Parts cannot be returned after they have been installed. This is the place I take mine: I bought a knock sensor with harness on eBay that was supposed to fit the J30. Here are two close-ups of the wire coming out of the harness on the sensor.
Start by consulting the wiring diagram for your vehicle from to determine which pin on the connector is power and which is ground. A knock sensor is like a small electronic microphone that is usually attached to the engine block and listens for a couple of things that a engine might do. Take off the knock sensor. The knock sensor doesn't pull in a strong input like it does when it's attached to the engine block. This is a little tricky and took me a few hours to figure out, but can be done in a couple hours easily.
The sensor in a Nissan plays a passive role, so the engine may run fine without it functioning, but it will throw a code. 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 engine in your Vehicles is designed to detect high-frequency vibrations caused by irregular detonation combustion. Purchased connector and knock senor and relocated sensor to the top of intake manifold because the original one was faulty and didn't feel like taking apart engine just to replace a 20 dollar part. The clear one looks like its on the right side but hard to tell.
Thankfully the shop does a lot of custom modding and fabricated a new piece from stainless steel piping. I'm going to give it another attempt before bringing it to the shop. The only way to get at it is to remove the plenum and the intake manifold. I was supposed to find the engine compartment end of the harness, plug in the new knock sensor and then mount it securely elsewhere on the engine. I would make sure it is the real problem before replacing. Reconnect the vacuum tube electrical connection. It leaves little room for hands and tools.
Make sure the engine is cold. At idle cylinder 1 would not fire causing a major rough idle. Remove brake calipers and tie up out of the way… You have to turn the key on so that you can put the gear shift in it's lowest position to get it out of the way. Even with the service manual I had a tough time finding it. Do you know of a lower price? You could probably do it with a cheaper sensor, but getting the correct harness is very important. Pictures of the short block casting helped me. Question: My 97 J30 has thrown the P0325 code about 10 times over the last 2 months.
