Re:knock sensor

not if you disable the knock board in the ROM

otherwise yes, without it the ECU will limp...

Re:knock sensor

hmm, thats wierd, cuz i know more then 10 people without the knock sensor, and the CEL doesnt even come on, these are on 0bd0 and 1 and 2 cars... so the price is wrong my friend, even though you chip ecu's you are wrong. For example, there is a SIR 2 b16a in a 92 civic si infront of my house with a p30 ecu and no knock sensor, no CEL, and another example my Accord h22a with p72 with no Knock sensor, and it runs just fine, doesnt through a CEL (but it does throw the code..) Vtec still works, all that ----, on both cars that are infront of my house, same with my other friends..

Re:knock sensor

no you don't have to. you will get the code (23), but your cel, won't be on and there are no affects from it, i found this out the hard way, i broke my knock sensor (literally broke it apart) and then just assumed my cel was on from it, so i didn't check my codes, after i was informed that a knock sensor won't cause the symptoms i had, i checked my codes, and i had forgot to hook my tps back up

now that i did, the car runs fine, i get a cel for my iac for some reason, but the engine still shows the code for the knock sensor.

Re:knock sensor

this post may old, but you dont need a knock sensor if you use a p28 ecu, but chip it to raise your your redline, and vtec to the b16 specs. thats what I did.
