1998 Where do knock sensor wires connect at ECU
I have a 98 LS400 and one of the knock sensors is bad (according to ODB2) and this is causing a CEL. In my city I can't pass inspection with a CEL even though I pass the emissions test.
Seeing as I don't have the cash or time to take off the intake and replace those I was trying to find out which pins on the ECU are the knock sensors so that I can compare with the good one and rig the wire going to the ecu for the bad one, maybe put a resistor or tap into the good one and put a diode and have it feed into the ECU for the second one. Anyway I have a few ideas but I need to find a wiring diagram or at least know which pins on the ECU are for the knock sensor.
Can anybody help?
