Anyone out there having a solution to their blown knock sensors? I'm considering the ATS racing Knock Sensor or re-wiring bank 2 to the bank 1 sensor. Which solution do you recommend?

I still have not resolved mine yet either.

Trying to avoid spending 125$ X2 on some new ones.

Pulled the top off of the motor and found that the entire valley the sensors sit in, was at one time filled with water. Tons of rust and scale inside. pulled the sensors out, cleaned them off, tested them. No short to ground, but the connectors were in quite poor shape, so I fixed those up. Tested the circuit between the sensors and the comp, and there was good continuity, but the sensor connector at the computer was grounded out. I thought that did not sound right, so today I replaced the computer.

Still pops a code 52. Extremely frustrating!!! Next plan is to buy 1 sensor wire the 2 together and call it good. There's a thread on here somewhere about doing it, i'll drop a link to it when I find it.

I would say that if you're doing it yourself, then you may as well try wiring them both to one sensor, and relocate them while you're at it.

if you make sure that you're running high octane gas and you have your a/f set up with proper boost, then you shouldn't have to worry about knocking or pinging anyway

one suggested place in the past is relocating the knock sensor to the front engine lift hook- it'll still get vibrations if they are extreme, and yet it won't be as sensitive as on the block

did you ever hit the dyno after you got your headers/y-pipe/exhaust setup? I know you got it tuned after...

Is it as simple as just wiring the two clear wires together and connecting it to the knock sensor???

drducttape: The code I'm getting is P0330 (Bank 2 Knock sensor). Have you hear of the ATS knock senor? The link is www.atsracing.net - look under knock sensor.

Kingston: As for your question, I never did get a chance to dyno it after my y-pipe mod, but it was running just fine.

My knock sensor malfunctioned in November when I put in some bad gas. I've been driving with the CEL for about 2 months now. I'm just waiting for my larger injectors before I change out my knock sensor.

Hah! ATS as about 10 minutes from my house, how wierd!! Could not see anything about a knock sensor there, but I'll look some more.

Found it! looks good, I may go pick one up today if they are open.

Jesus must have sent you!! I've been looking for a local place with a Dyno. 3 pulls for $65!! Not bad!

They are open Mon-Fri though, so I wont be picking up mine today. Tuesday will be the day then.

THANK YOU!!! THANK YOU!!! THANK YOU!!!

^ No problem! Glad I could help. Can you find out if the ATS knock sensor is a direct plug and play for our camrys.

I'm positive that they will screw into the block with their provided adapter, but you will have to snip your old electrical connector off, and install the supplied one to make it work.

Drove by the place about an hour ago, looks like a hole in the wall, but those tend to be the best places around.
