Review: Resolved my check engine light. - Awesome fit. States it didn’t fit my vehicle but after some research, I found that it would. I installed them and after a test drive, no codes returned and it resolved my problem. Much cheaper than the OE and after a week seems to be the same performance as well. Would recommend this kit for a dealer alternative. The comparability for these sensors is very wide for Toyotas.
Review: Cheap knock offs - Don't follow torque specs on these. I broke one off in the cylinder head. Fortunately I was able to extract it. Good price though. One sensor at the parts store was 83 bucks! Update, these are cheap knock offs. just buy Denso Toyota brand ones and be done with it. The cost of time and parts to tear the top end off a second time is more expensive!

## 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.

### ⭐⭐⭐⭐⭐ Great product!
*by M***E on July 11, 2026*

Used this to trick the computer in my Toyota Sienna into thinking that the original knock sensor was working properly. By mounting it somewhere stable and bypassing the one in the block it worked like a charm. Dorman products are top notch.
