02 voltage question
02 voltage question Ok, so in my ongoing battle to remedy my 02 problem (car keeps throwing p0134), I went ahead and hooked a volt meter up to the 02 harness extensions. With the key turned on, but the motor off, I got the same voltage outputs for both front sensors, on the pink and tan wires. There was no voltage output for either purple wire on either sensor. The car never throws any codes for bank 1, sensor 2, so is that purple wire not supposed to have any voltage when the key is turned on?
