## Description

Complete solution - this knock sensor kit includes two knock sensors and the wiring harness that connects them Plug-and-play installation - matches original wiring harness, requiring no cutting or splicing Quality assured - benchmarked against original components for performance and quality Excellent value - original equipment quality at significant cost savings Ensure fit - to make sure this part fits your exact vehicle, input your make, model and trim level into the desertcart Garage

Review: Works so far - This installation took me very very very long. I ended up getting a set of gaskets, an angled ratchet for those stubborn bolts behind the plenum. I also did the spark plugs and ignition coils, half are buried under the plenum. Save yourself some money and buy them from RockAuto if you are in Canada, amazing prices, fast shipping. Also, get some coolant or drain it beforehand because it'll need replacing. Overall, hoping that these things last. Will update if anything changes.
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.

## 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.
