harness connection
no problem connecting to the two knock sensors but the connection to the cars harness was poor. Would not snap together and I had to improvise with electrical tape to make the connection. Cant say I was satisfied but I was able to solve the CEL issue.

Lexus RX300 repair
Fit perfectly. Check engine light cleared and running great!

By far the least expensive way to go because it comes with both sensors and the harness as well which is what makes it such any affordable option. Most places wanted 70 to 90 for a single sensor.

2003 Sienna
Good Price on the product and it fit the application. Having both sensors and the harness was good due to the location of the sensors.
February 23, 2018
Perfect fit.
Always good service from A1. The product worked perfectly and solved my warning light problem. These are buried deep in the engine so having a quality product is really satisfying. I wouldnt shop anywhere else.

Harness Wouldnt Clip In
The knock sensors fit perfectly but the Sensor Harness wouldnt clip into the factory harness after removing the original harness. Had to come up with my own solution to get the male/ female ends of the harness to stay together.

Parts were a good price, on time delivery, working perfect in the car. Would definitely use them again.

The knock sensors fit very well...the harness clicked into place well with the sensors, at the main connection doesnt click on but stays in place...the gaskets are perfect fit and so are the sparks!

Knock sensors worked great harness connector bad
The knock sensors worked like they should but the harness wouldnt stay plugged in. The tab that connects to the detent on the connector wouldnt hold. Just kept coming unplugged. Had to get another one off a salvage car engine to make it work.

Does not Fit Camry V6
The part was supposed to be OEM equivalent, but it did not fit. The sensors fit properly, and the connectors mated with each knock sensor correctly. However, the other connector (4 pins) did not mate properly. It seated correctly but it would not snap into place. I tried all kinds of things, but couldnt get it to click in - though it seemed REALLY close. I ended up cutting off the connectors for the old and new harnesses, and then soldered the old connector (known to fit) onto the new harness. It worked fine, but took me an extra hour of effort. I called 1A Auto to see if they would do something for me for the bad part they sold me, but they would not. They said I should have called and then ordered a replacement. Unfortunately, I had the top part of the engine torn apart and did not have time for replacement parts via mail. Regardless, they said the part would fit and it did not. I try never to say never, but am having a hard time imagining buying anything else from 1A Auto.

Lexus picky about knock sensors
giving this a 3 star review because I am having to replace the knock sensors again with OEM parts, like others I’ve seen review this product. Shipping was fast. The O2 sensors, and knock sensor harness both worked. I purchased the knock sensor kit that included both knock sensors, and the harness, although only knock sensor 1 was showing bad. It was cheaper to get the kit than to order one OEM sensor. But it is now costing me an additional $600 to have the knock sensors replaced with OEM parts because the engine does not like aftermarket knock sensors. I have a 2000 Lexus RX 300 with 228K miles. Invest in OEM knock sensors to save yourself a lot of time, and money!!!

Saved me about $650 for these parts!
I got an estimate from my repair shop that it would be about $1100 to fix my knock sensors to get my check engine light to go off. Its an old car and not really worth that much, so I decided to double-check with a friend. He said the expensive part would be the knock sensors-harness kit and it was very labor-intensive, but he would do it for a very reasonable price. I looked online and found the Toyota knock sensor-harness kit for about 1/3 of what he told me it would probably cost. It saved me a big chunk of money for him to do the work and it runs better than it ever has! Thanks!

I purchased this kit last year and it installed with no issues and I no longer received an engine warning light. As far as it being OEM, Im not sure as this stands for Original Equipment Manufacturer and I dont know who manufacture is.
Daniel P April 7, 2016
No, this is an aftermarket product but I have had no problems with them.
Josh N May 17, 2016
Will the wire harness fit perfect with the connections on my 2000 toyota Avalon XLS as well as the knock sensors that comes with?
Patrick C May 11, 2017
As long as your vehicle is a V6, 3.0L engine the wire harness will be a plug and play.
