I need some help on how to bypass the knock sensor on my KA. I just need the CEL off to pass smog. I was going to do the 1m resistor trick and just need some exact instrustions on how to do it.
If anyone can help me by showing pics that would be great. thanks

i have a knock sensor promblem and my check engine light comes on too. all i did to turn it off and to pass inspection was have friend reset it with a scanner

hmmm.....what year 240? just remove the CEL bulb lol, also b4 smog test make sure timing is set properly and run seafoam thru vac line and change out spark plugs and drive for a bit then smog it so it reduces HC

well just make sure you hide the plug with the resistor...smog tech sees it...they will fail it....just remove the bulb much easier also only work if its 95 and below 1996 and above they have to plug it in the smog machine for OBD 2 diagnostic

cant they fail it when they check if the lights work before they start the smog test?

no, just keep your mouth shut let them smog it, they don't care as long as your EGR works and cat is installed they just want you in and out

WTF are you talking about.
if light stays on you fail inspection.
they always turn off the car and see if the CEL light gets illuminated when turning the key in position.

if it doesnt get lit up, that means you took out the bulb. FAIL.

another trick is to wire up your CEL light to the oil light.

hope it works for you.

good luck.

Another Q, the plug that connects to the knock sensor from the ecu is it 2 black wires? and what harness does it come out from? i cant find it on a sohc

I've always been told that a knock sensor code won't throw a CEL. Mine sure doesn't.

What code are you throwing? How do you know its the KS? cuz its usually not

have you even read the codes from the ECU? it might be your EGR valve common KA24E problem...u best fix the EGR if you want to get it smogged...they will test it with a vacuum pump to see if its working

Think obd1 no and obd2 yes..or i was told something along those lines. Cause I have a 95 I never got a cel, but have code 34

There is no knock sensor for the SOHC...somthing else is wrong.
