Review: Thumbs up - Installed on 02 es300 work car with 340k miles a while back. So far so good. Before I changed them, the car wouldnt run right. It had no power and wouldnt go into O/D. I cleared the code when I replaced them and problems solved.
Review: Worked... Until it didnt - It solved the problem for about a month and then bam, code showed again and guess what one of the codes was, go ahead and guess... Correct, knock knock, who's there... (Insert angry face here)... I had the codes read and top of the list, knock sensor. I did some digging and found the harness connector could be the issue. I went and disconnected and made sure it was tight. To no avail... I quit! Makes me wonder if it's legit Dirman parts.

## Questions & Answers

**Q: Did it fit as intended on a toyota camry?**
A: My application was for 2002 Toyota Sienna.  The wire harness did not easily fit into existing connector.  The knock sensors did however on the other side but final result - it did not fix my issue.  My code P0330 (bank 2) ended up into P0325 (Bank 1) and did not fix the issue yet.  I asked for a replacement from AMAZON and will install a new set in the weekend of Aug 7/8- 2021.

### ⭐⭐⭐⭐⭐ Worked perfectly
*by M***X on January 25, 2026*

Took away the knock sensors codes. Could've been just the wiring hardness but with the amount of work simply you access them, Just do both.
