Owner reviews for knock sensor

The metal casing that surrounds the wire is actually the ground. Subaru unfortunately does not sell or replacement part for this. The easiest and complete fix is to go to the junkyard find one with that wire complete pull it out from the base and replace it.

Replaced the knock sensors in my 02 suburban recently.

NTK all the way. I went through one or two other brands from rock auto and that's the one that worked.

I bought the NTK one (part number ID0213) from Rockauto for \\~$33 after shipping back in March, along with a generic pigtail from Amazon. So far, the code has not returned, but I've only logged 125 miles since installation.

Have you replaced your knock sensor? If it’s bad, it might be sending false knock readings to the ecu. It might be the reason the fuel mix is so rich.

My knock sensor is maybe a year old. It's Bosch... but Bosch China.

i threw a 2nd cel had it scanned, the scan said \"knock sensor implausable signal spurratic\" had it cleared about 7,100 it came back on, had the senor replaced...

Second , the KIA Soul with the check engine light going on snd off due to faulty knock sensors. Software Updates made and warranty extended to 150k and shortly after same issue again.

Bought a Delphi knock sensor in late 2023 to replace failed stock sensor my 2004 Honda Element. I assumed Delphi was a trusted brand. The sensor did not solve the ECU code, even after clearing the code several times, and reseting the ECU. The CEL would reappear immediately or within driving a half mile. Assuming is was a hard to find wiring issue, I drove the vehicle with the Check Engine Light on for a year and a half. Recently, a 26-year Honda/Acura mechanic told me the 2003 and 2004 Elements are famous for failed knock sensors and I should use a genuine Honda part (from junkyard on 2005-later engine) or new from dealer. Skeptical, I bit the bullet and paid the price for the genuine Honda sensor. Cleared the CEL, installed the sensor, and have now driven over 600 miles with no sign of bad knock sensor. Lesson learned.

Now my check engine light is on and I\u2019m just over 5000 miles in a 2019 SEL R-Line. The code says weak knock sensor 1 signal same code as before.
