If you’re a Ford driver and your vehicle is showing a PO161 error code, this article is for you. We will provide one practical solution to fix the error code at home.
Identifying the Error Code
Use the Zeus app to scan your vehicle and see the error code PO161. This code indicates that the engine control module has tested the oxygen sensor heater circuit and detects a problem with the bank 2, sensor 2 oxygen sensor heater circuit.
Solution: Oxygen Sensor Check
The practical solution involves checking the oxygen sensor. This sensor is located right after the catalytic converter. Bank two is on the side with cylinder number two, and sensor number two is usually the downstream oxygen sensor behind the converter. Visually inspect the oxygen sensor’s electrical connections, wire harness, and metal tabs for any damages.
If damages are found, replace the oxygen sensor. However, if there is no damage found, you would need to take your car to consult professional mechanics.
Final Steps
After the repair, you can use the Zeus app to clear the error code and tap the rescan button one more time to ensure everything is fine with your vehicle.
