The GM part 12640453 Oxygen Sensor supports peak engine efficiency by tracking exhaust fumes through dual oxygen sensors connected before and after the converter. The pre-converter oxygen sensor controls fuel injector pulse width through its voltage output signals that detect exhaust oxygen residuals while the powertrain control module (PCM) maintains an air/fuel ratio at 14.7:1. Without altering mixture control the post-converter sensor enables the PCM to evaluate the catalyst efficiency. The correct operation of oxygen sensors depends on proper electric circuit wiring, sufficient air flow along with acceptable temperature levels and lead-free fuel standards. Management of the system requires regular examination because detected problems force the PCM to activate open-loop fuel control mode that potentially affects system performance levels. The servicing procedure for GM part 12640453 requires sensor damage prevention together with connector protection while the post-converter sensor requires elevated vehicle position to access it properly. A ratchet wrench or socket serves recommended purposes for removal while anti-seize compound application during installation provides the optimal result.
