There is a way to bypass it just enough to pass emissions, but I have not tried it. Check the internet, there is a shady way of doing it by rewiring through the glove box. I have a 96 Avalon with 197,000 and it is BY FAR the best car ever manufactured. I ultimately replaced the failed knock sensor and the oxygen sensor, spark plugs, etc while engine was torn apart. The car was my high school graduation present back in 02 and I wanted to keep it on the road for as long as I can. It sucks that something as simple as a knock sensor is buried deep in the engine and costs a fortune to replace, but if you are like me and know a mechanic willing to work for cash in your driveway its worth doing.

Hello. To answer your question, the answer is no. You cannot disconnect it, bypass it or defeat it. The Knock sensor is critical to preventing detonation (valve 'ping'). Sorry that I do not have abetter answer, but, the Knock is indeed important.

Hello, i have a 1996 toyota avalon check engine light on had it checked out. The code read p0325-bank1 knock sensor signal level low or open/shorten. Which sensor is bank 1

Bank 1 are the cylinders closest to the firewall. Bank 2 are closest to the radiator on transverse (sideways v6) engines. Unfortunately, the intake manifold must be removed to access the knock sensors. The sit right under it. Once the intake is removed, you will see two wire leads. Each one plugged in to a knock sensor.


Hope this helps Ray.

My 96 maxima wont pass emissions in az after replacing 02sensor and knock i need to drive it to reset comp?

I would say 10 to 20 miles would be enough to tell if the trouble codes will return. You may be able to disconnect the battery for a couple of hours to clear the codes, but using a scanner or code reader is better.
A scanner or code reader can find history trouble codes on some models and in some cases without the engine light being on.
The purpose of the warning light is to tell the driver the vehicle needs attention now.

Hello people i got a gmc 99 jimmy 2door sls the engine light keeps coming on then going out ive coded it to be an iat sensor and also says the iat sensor intermitten voltage high and then the knock sensor...

the IAT may be bad or the connector is bad, real common (friend should know to check that) get a real scanner and see what the IAT is reading, then move the connector and see if it changes. if it reads -40f then its bad or disconnected.

Could it be that my engine light on is due to it being dirty just brought it it does not have a manuel runs good over 200,000 miles whats your answer

From the milage, it seems that you need to replace the oxygen sensor, thats what makes your engine light go on initially, have the sensors reset with a scanner first, if the light comes back on, then the oxygen sensor will pretty much be your next fix.
Good luck.

I have a 1996 Toyota Avalon XLS V6. Engine light is on and im told i have a bad Knock Sensor. It has 2 and @ $150ea. Is there a cheaper or way to fix or bypass this problem? Ther isnt any knocking or...

i honestly have never seen a knock sensor go bad. a knock sensor detects spark knock,which is from low octane gas. if it hears this then the ecm retards the timing to stop the knock. you wont be able to hear the knock that its listening for. its like a little microphone stuck in the block. before you replace it you might want to check the plugs on the sensor itself. if they are corroded they could cause this problem.. ANYTIME you have engine codes ,always check your ground cables on the engine and the battery. i work in the marine industry and you would be amazed all the codes you can get just from having a corroded battery i said , i have never seen a knock sensor go bad..

98 Nissan Maxima - Check Engine Light, Knock Sensor

If the car is pinging you will set a knock sensor code.'
This comes from bad gas and running lean., You really need this professionally inspected to rule out the basics. I have seen alot of nissans with the knock sensor code stored but the light is still off.
Fill up the tank with high octane chevron and some techron injector cleaner and clear the light. If it stays off for a couple days then go get it inspected. Even if the code is stored it will still pass as long as the light is still off and the monitors have run.

You need to pull off the entire intake manifold/plenum assembly. The knock sensor is bolted to the inside of the cylinder block, it is in the middle of the culinder block.
