Worked Great, Shipped Quickly

It arrived on time and worked great. My old knock sensor was giving an error, but since the 2000 Nissan Pathfinder has it's knock sensor directly in the center of the engine, it was easier to relocate the sensor as well. I spliced the new wire harness into the old one and secured the sensor to a new, more easily accessible area. It's doing great!

Part was made wrong.

Great price for the part. Saved us over 100$. Only issue was the harness, the part was on backwards. So it wouldn't line up with the original part for me car. The sensor its self fit like a glove.

Hey world you can't beat the price and promise to deliver parts in a timely fashion, I'm calling on 1a when ever I need parts e.t.c.

Knock sensor

Joe

Item is like it's description and it work perfectly

knock sensor relocate

This kit is perfect for relocating the knock sensor on the Nissan V6 I used the new harness and sensor to place the sensor on the top of the manifold for easy access. It looks like a factory installation with the harness and sensor properly shielded.

Great quality at the best price all-around.

I tried to buy this part at the local auto parts shops but the prices ranged from 150 without the cable plus an additional 65 for the cable. The lowest I found was $90 for the sensor and $45 for the cable. I am so happy to have bought the knock sensor kit at such a low price, once I got the part in the mail I had my local mechanic install it and it works perfectly. I highly recommend this store, because of the reasonable prices and quick mail delivery, the best thing is that the parts are high quality. From now on whenever I need a part for any of my cars this is the store I will be checking first.

Knock sensor and harness Nissan altima 2001

Knock sensor took the engine light off. I tried earlier with auto zone version but it didn't work. Harness has reversed plugg shape. Couldn't use it as a replacement. I guess I could cut off the old one and pair it with the new one. Needs little work but I'm very happy with the quality.

Good knock sensor

Daniel

Easy & smart knock sensor idea

Rigoberto

I am a heavy duty mechanic, hardly work on smalll vehicles because they are so compact and complicated like this knock sensor that you have to destroy top of the motor to replace it but thanks to this relocation harness and new knock sensor idea it can happen in 30 minutes, Thanks1aauto.com

My order came on time it was the perfect match quality is great price was perfect for my budget much cheaper than I had seen other places online and in discount auto parts stores. I will if needed be shopping with '1 A Auto' again..

Wrong Connector

R-Kurt-H

It is the wrong connector for a J30 Infiniti so I had to rewire it using the old connector. Many other people all over the internet have noted this same problem. After rewiring it worked fine

First time-great experience

I have learnt about 1AAuto by watching one of yours very good how-to videos. Your web site is as good! Found a part I needed in no time, your price beats competitors, delivery time as promised and got the credit back when had to return the part customer service is very friendly and COMPETENT! Overall 10 points out of 10 and will be back! Keep up great job!

Somehow the knock sensor came with a dummy wire that doesnt go anywhere and is just there for no reason, LMK if that supposed to be like that or just mine came that way?

Cody

Worked out pretty good. The connector on the new harness wouldn't plug in to the harness on the car but was able to switch the one off the old harness and make it work.

Thank you for your inquiry! The transmission sensor will plug into a harness on the vehicle, but unfortunately we do not have the exact part number or name for it.

Ive been purshasing my auto parts from 1a auto for the past 3 or 4 years and their parts are the same or almost equal quality as original. On my 2000 Altima the knock sensor was very difficult to reach from the hood so I at the time also needed a major engine repair that I had to take it to a mechanic who also installed the sensor. As of today the knock sensor code does not come up when scanned.
