What to do if your OBD says code 23?
If they are not reconnected, code 23 will set. A quick test for the intake air temperature sensor circuit from the ECM would be to unplug the temp sensor and watch the intake air temperature sensor reading on the scan tool while jumping the harness side of the sensor connector.
Why is the code 23 on my air cleaner?
Sensors are often unplugged when checking the air cleaner. If they are not reconnected, code 23 will set. A quick test for the intake air temperature sensor circuit from the ECM would be to unplug the temp sensor and watch the intake air temperature sensor reading on the scan tool while jumping the harness side of the sensor connector.
What does trouble code 23 on mat sensor mean?
Trouble Code 23 indicates that the Manifold Air Temperature (MAT) sensor is reporting abnormally low readings. When the air is cold, the thermistor in the sensor has a high resistance, which falls as the air charge warms.
Why do I have a code 23 on my engine?
Share it! The Intake Air Temperature sensor relays the current temperature of the air entering the engine to the Engine Control Module. The ECM uses the information from this sensor to help calculate fuel delivery and spark timing. A disconnected Intake Air Temperature sensor is the most common cause of a code 23.
