Throwing the code open circuit short to positive, checked wiring on pin 1,3,4 to ecu all fine and have battery voltage on pin 2 which is shared with the upstream 02 sensor (green/red) when engine is running i have 14v on pin 2 and 12v on pin 1 is pin one ment to have that ? The code erases but come strait back on when engine started also i have no oil in connectors and have replaced engine breather pipe under manifold ? Any ideas thanks
