Code P0137 2007 Ford Fusion Description
The P0137 code indicates that the O2 sensor circuit for Bank 1 Sensor 2 is registering a low voltage condition. This sensor is responsible for measuring the oxygen content in the exhaust gases after they have passed through the catalytic converter. The voltage signal produced by this sensor is used by the engine control module (ECM) to adjust the air-fuel mixture for optimal combustion. A low voltage reading from the sensor can disrupt this process, leading to poor engine performance, decreased fuel efficiency, and increased emissions. If left unresolved, this issue can potentially cause damage to the catalytic converter, resulting in costly repairs.
Common Causes of P0137 2007 Ford Fusion
- Faulty O2 sensor
- Wiring issues or corrosion in the sensor circuit
- Exhaust leaks near the sensor
- Engine misfires
- ECM software issues
Symptoms of P0137 2007 Ford Fusion
- Decreased fuel efficiency
- Rough idling or stalling
- Check Engine Light illuminated
- Poor acceleration
- Increased emissions
How to Fix P0137 2007 Ford Fusion
- Use a scan tool to confirm the P0137 code and identify the specific sensor location.
- Inspect the O2 sensor wiring and connector for any damage or corrosion.
- Test the O2 sensor using a multimeter to check for proper voltage output.
- Replace the O2 sensor if it is found to be faulty.
- Clear the code and perform a test drive to ensure the issue has been resolved.
Cost to Fix P0137 2007 Ford Fusion
The cost of repairing a P0137 code on a 2007 Ford Fusion can vary depending on the specific cause of the issue. In general, the cost of replacing an O2 sensor can range from $100 to $250, including parts and labor. Additional costs may be incurred if wiring repairs or other components need to be addressed. It is recommended to consult with a qualified mechanic or auto repair shop for a more accurate estimate based on the individual circumstances of the vehicle.

Frequently Asked Questions about P0137 2007 Ford Fusion Code
1. What does the OBDII code P0137 mean for a 2007 Ford Fusion?
P0137 indicates that the oxygen (O2) sensor circuit for Bank 1 Sensor 2 is detecting a low voltage, which could suggest a lean air-fuel mixture or a sensor malfunction.
2. What are the common symptoms of code P0137 in a 2007 Ford Fusion?
Symptoms may include reduced fuel efficiency, rough idling, an illuminated Check Engine Light, and potential difficulty passing emissions tests.
3. What causes the P0137 code to appear in a 2007 Ford Fusion?
Common causes include a faulty Bank 1 Sensor 2 O2 sensor, damaged wiring or connections, exhaust leaks, or issues with the engine control module (ECM).
4. Which O2 sensor is Bank 1 Sensor 2 in a 2007 Ford Fusion?
Bank 1 Sensor 2 is the downstream oxygen sensor located after the catalytic converter on the side of the engine with cylinder 1.
5. Can I drive my 2007 Ford Fusion with a P0137 code?
While the car may still be drivable, prolonged operation with this code can lead to increased emissions, reduced fuel efficiency, and potential damage to the catalytic converter.
6. How do I fix the P0137 code on my 2007 Ford Fusion?
Repairs may involve replacing the faulty O2 sensor, repairing damaged wiring, checking for exhaust leaks, and ensuring the ECM is functioning properly.
7. How can I test the Bank 1 Sensor 2 O2 sensor in my 2007 Ford Fusion?
You can test the sensor using a multimeter to check voltage output or by using a scan tool to monitor live data for abnormal readings.
8. Could an exhaust leak cause the P0137 code in a 2007 Ford Fusion?
Yes, an exhaust leak before the downstream O2 sensor can result in incorrect readings and trigger the P0137 code.
9. How much does it cost to repair the P0137 code on a 2007 Ford Fusion?
Costs vary depending on the issue but typically range from $100 to $300 for parts and labor if replacing the O2 sensor is necessary.
10. What happens if I ignore the P0137 code on my 2007 Ford Fusion?
Ignoring the code can lead to decreased fuel efficiency, higher emissions, and potential damage to the catalytic converter over time.
