The heating OXYGEN SENSOR HEATER MONITOR (SBEC) DESCRIPTION—If there is an oxygen sensor (O2S) DTC as well as a O2S heater DTC, the O2S The voltage readings taken from the O2S are very temperature sensitive. The readings are not accurate The heater element itself is not tested directly. The sensor output is used to test the heater by isolating OPERATION—The Oxygen Sensor Heater Moni- tor begins after the ignition has been turned OFF When the oxygen sensor is cool enough, the PCM energizes the ASD relay. Voltage to the O2 sensor increases, the internal resistance decreases. The PCM continues biasing the 5 volt sig- LH EMISSIONS CONTROL 25 - 3 EMISSIONS CONTROL (Continued) |
