Details of the Ford p0147 OBD Code
Ford code P0147 relates to the O2 sensor circuit low voltage condition in bank 1 sensor 3.
Ford OBD code P0147 means the O2 sensor heater circuit is low voltage for bank 1 sensor 3. This code is triggered by the Engine Control Module (ECM) when it detects a low voltage condition in the O2 sensor heater circuit for the third oxygen sensor on bank 1 of the engine.
The O2 sensor heater circuit is responsible for quickly bringing the oxygen sensor up to operating temperature for more accurate readings.
Mechanic’s Tech Notes
For Ford code P0147, the rear oxygen sensor circuit voltage is low.
OBDII code P0147 in a Ford typically indicates an issue with the TCM (Transmission Control Module) temperature sensor circuit.
To diagnose, use a voltmeter to test the sensor’s resistance and compare it to specifications.
Check the wiring harness and connectors for any damage, corrosion, or loose connections.
Ensure the TCM is receiving proper power and ground.
Use a scan tool to monitor TCM data and confirm communication over the CAN network.
If all checks out, consider reprogramming or replacing the TCM.
