Either way, a heater low or high voltage is something that must be diagnosed before you automatically replace the sensor. If there’s no voltage drop, the ECM assumes there’s an open in the circuit. The issue can be increased resistance in the power feed to the heater (usually caused by corrosion in the connection or splice). If the voltage drop is higher or lower than expected, it knows there’s a problem. If it sees a large voltage drop, it knows the heater is getting power. When you start the engine, the ECM knowns the oxygen sensor is receiving power to the heater by monitoring the heater ground voltage. How the ECM checks the oxygen sensor heater ![]()
