Does anyone have or know where i can find the pin-out for the power-train control unit(ECU)? i want to trace the wires coming from the B1,S1 02 sensor back to the ECU. Gonna be doing some DIY diagnostic on maybe some faulty wiring. I'm getting a no circuit activity code(P0134). I replaced the 02 sensor for that bank with a OEM unit i got from Amazon but im still getting that code after resetting. Thanks in advance.
