Details of the p0163 OBD Code
P0163 indicates a malfunction in the sensor circuit of the O2 sensor bank 2 sensor 3.
OBD code P0163 means that the oxygen sensor circuit on bank 2 sensor 3 has low voltage.
This code is triggered by the Engine Control Module (ECM) when it detects a voltage signal below the specified range from the oxygen sensor located after the catalytic converter on bank 2 of the engine.
The ECM monitors the oxygen sensor signals to ensure proper catalytic converter operation and emission control.
Mechanic’s Tech Notes
Code P0163 indicates that the oxygen sensor circuit on bank 2 sensor 3 has low voltage.
OBDII code P0163 relates to the transmission control module (TCM) communication circuit.
To diagnose, use a voltmeter to check TCM power and ground.
Utilize a scan tool to confirm TCM response over the Controller Area Network (CAN) network.
If no response, reprogramming the TCM might be necessary.
Visually inspect wiring harnesses and connectors for damage, focusing on broken, bent, or corroded pins.
Ensure connectors are securely attached.
If the issue persists, consider consulting a professional for further diagnosis and potential TCM replacement.
