What does code 45 mean on the O2 sensor?
If there is little oxygen in the exhaust, it is in rich condition and the O2 sensor voltage will be high. The ECM uses this information to adjust the amount of fuel delivered to each cylinder. On V-type engines with two O2 sensors, code 45 would indicate the left bank sensor is rich
What does the code 45 mean on the ECM?
The ECM uses this information to adjust the amount of fuel delivered to each cylinder. Fault Code Description. 45 – Oxygen sensor error (rich condition indicated) On V-type engines with two O2 sensors, code 45 would indicate the left bank sensor is rich.
What are the trouble codes for the GM W-body?
VEHICLE SPEED SENSOR (VSS) CIRCUIT 25 MANIFOLD AIR TEMP (MAT) or INTAKE AIR TEMP (IAT) CIRCUIT (HIGH TEMP) 26 QUAD-DRIVER (QDM) ERROR (if applicable) 32 EXHAUST GAS RECIRCULATION (EGR) CIRCUIT 33 MANIFOLD ABSOLUTE PRESSURE (MAP) SENSOR (VOLTAGE HIGH-LOW VACUUM) 34 MANIFOLD ABSOLUTE PRESSURE (MAP) SENSOR (VOLTAGE LOW-HIGH VACUUM) 35
What does it mean when oxygen sensor fails?
Oxygen sensors being an important part of the emission system, if displays a trouble code in engine’s computer, it means the sensor has failed. A digital multimeter and a code reader can be used to identify the exact issue, and if the sensors failed, one can only replace them.

What does trouble code 25 mean on a thermistor?
Trouble Code 25 indicates that the Manifold Air Temperature (MAT) or Intake Air Temperature (IAT) sensor is reading higher than expected. When the air is cold, the thermistor has a high resistance, which falls as the air charge warms. High readings thus indicate possible short circuits in MAT circuit.
