i have a 94 accord with a jdm h22. i am running a code 23 (knock Sensor). the light only comes on when the car reaches operating temperature (closed Loop). I replaced the sensor and checked all wiring to the computer. its all fine. is it possible for the ecu to be bad. Everything came from HMO so ..... i need help cuz this is pissing me off for the last month. if anyone has suggestions i would apppreciate it.

 

well it 2 of 2 things, you wiring is bad, or you knock is dead.

the knock sensors are a very sensitive thing and i would not be surprised if it got screwed up in shipping.

check that you don't have an open in the wire you have going to your ecu, and check that the wire you have going to the ecu is on the right pin
