P0051 etc?

[DevilDawg3097]

keeps throwing a code P0051, I replaced the O2 sensor pass/ up stream. Why is it still throwing this code. I did notice I have a leaky header could that be? WTF

I would check the terminal contact for that O2 and also the wiring. Check for battery voltage at the brown with violet wire, that's the heater control circuit.

Recommend a visual inspection of the engine wiring harness be performed. Check for any aftermarket equipment installations. Check for blown fuses or damaged fuses. Visually inspect the O2 connectors (all) for any water intrusion, push outs, spread, or shorted pins. Follow the Diagnostics Procedure in TechCONNECT. These DTCs can be set due to a problem with the ASD output circuit having voltage when the ignition key is in the OFF Position. If there is voltage on the ASD output circuit ignition OFF Position this can damage the O2 Sensor heater monitoring resistor internally within the PCM circuit board. NOTE: If the PCM is replaced per the diagnostics and there is voltage on the ASD Output circuit with ignition key OFF the NEW PCM will be damaged. Result in replacement again. Make sure the ASD output circuit is checked for any voltage with ignition key OFF and correct shorts to voltage before PCM replacement. Note: Never jump 12 volts to the ASD output circuit(s) with the ignition key in the OFF Position. If all the above have been checked then PCM replacement is needed. See the service procedure for PCM replacement
