Code P0137 2011 Ford Fusion Description
The P0137 diagnostic trouble code (DTC) for a 2011 Ford Fusion indicates that there is a low voltage condition in the O2 (oxygen) sensor circuit for Bank 1 Sensor 2. This particular sensor is located downstream of the catalytic converter and is responsible for monitoring the oxygen content in the exhaust gases after they have passed through the catalytic converter. The O2 sensor provides feedback to the engine control module (ECM) to adjust the air-fuel mixture for optimal combustion efficiency. A low voltage reading from this sensor can indicate a problem with the sensor itself, the wiring, or the ECM.
Common Causes of P0137 2011 Ford Fusion
- Faulty O2 sensor
- Damaged wiring or connectors in the O2 sensor circuit
- ECM software or hardware issues
- Exhaust leaks near the O2 sensor
- Contaminated or poor-quality fuel affecting sensor readings
Symptoms of P0137 2011 Ford Fusion
- Check Engine Light illuminated on the dashboard
- Decreased fuel efficiency
- Rough idling or engine misfires
- Poor acceleration or lack of power
- Failed emissions test
How to Fix P0137 2011 Ford Fusion
- Perform a visual inspection of the O2 sensor and its wiring for any signs of damage.
- Test the O2 sensor's voltage output using a multimeter to confirm low voltage readings.
- Replace the Bank 1 Sensor 2 O2 sensor if it is found to be faulty.
- Repair or replace any damaged wiring or connectors in the sensor circuit.
- Clear the DTC with a scan tool and test drive the vehicle to verify that the issue has been resolved.
Cost to Fix P0137 2011 Ford Fusion
The cost of repairing a P0137 code on a 2011 Ford Fusion can vary depending on the specific cause of the issue. However, as a rough estimate, replacing an O2 sensor typically ranges from $100 to $200 for the part, with additional labor costs of around $100 to $200. Keep in mind that diagnostic time and labor rates at auto repair shops can vary, so it's advisable to contact local shops for a more accurate estimate.

Frequently Asked Questions about P0137 2011 Ford Fusion Code
What does OBDII code P0137 mean for my 2011 Ford Fusion?
OBDII code P0137 indicates that the O2 sensor circuit for Bank 1 Sensor 2 is experiencing low voltage, which typically means the sensor is not providing a proper signal to the engine control module (ECM).
What are the common symptoms of P0137 in a 2011 Ford Fusion?
Common symptoms include a check engine light, decreased fuel efficiency, rough idling, and increased emissions.
What could cause the P0137 code to appear?
Causes can include a faulty oxygen sensor, damaged wiring or connectors, exhaust leaks near the sensor, or issues with the engine control module.
How do I diagnose the P0137 code in my Ford Fusion?
Start by checking the wiring and connectors for any damage or corrosion. Then, test the oxygen sensor's voltage output with a multimeter. If the sensor is faulty, it may need to be replaced.
Can I drive my 2011 Ford Fusion with the P0137 code?
While you can technically drive the vehicle, it is not recommended due to potential decreased performance and higher emissions. It’s best to address the issue as soon as possible.
What is the location of Bank 1 Sensor 2 in a 2011 Ford Fusion?
Bank 1 Sensor 2 is typically located after the catalytic converter on the exhaust system, on the side of the engine where cylinder number one is located.
What repair steps should I take if I see the P0137 code?
Start by inspecting and repairing any damaged wiring or connectors. If those are intact, test or replace the oxygen sensor. Clear the code and take the vehicle for a test drive to see if the code returns.
Will replacing the O2 sensor always fix the P0137 code?
Not necessarily. If the sensor replacement doesn’t resolve the issue, further diagnosis may be needed to check for wiring problems or issues with the engine control module.
Is it necessary to reset the check engine light after fixing the P0137 code?
Yes, after repairs, it's recommended to clear the check engine light using an OBDII scanner to ensure that the code does not reappear after fixing the underlying issue.
