Code P1137 2001 Ford F150 Description
The P1137 diagnostic trouble code (DTC) for a 2001 Ford F150 indicates a lack of heated oxygen sensor switches Bank 1 Sensor 2 switch indicates lean. This means that the oxygen sensor located downstream from the catalytic converter on bank 1 is not operating properly and is detecting a lean air-fuel mixture in the exhaust gases. The oxygen sensor is responsible for measuring the oxygen content in the exhaust gases and sending this information to the engine control module (ECM) to adjust the air-fuel ratio for optimal combustion.
Common Causes of P1137 2001 Ford F150
- Faulty heated oxygen sensor (Bank 1 Sensor 2)
- Wiring or connector issues related to the oxygen sensor
- Vacuum leaks in the intake system
- Exhaust leaks near the oxygen sensor
- Fuel system issues such as a clogged fuel filter or failing fuel injectors
Symptoms of P1137 2001 Ford F150
- Decreased fuel efficiency
- Rough idling or engine misfires
- Hesitation or lack of power during acceleration
- Check Engine Light illuminated
- Failed emissions test
How to Fix P1137 2001 Ford F150
- Perform a thorough inspection of the heated oxygen sensor (Bank 1 Sensor 2) and its wiring for any visible damage or corrosion.
- Test the oxygen sensor using a multimeter to check for proper voltage output and response time.
- Check for vacuum leaks in the intake system and repair any damaged hoses or gaskets.
- Inspect the exhaust system for leaks near the oxygen sensor and repair as necessary.
- If the issue persists, consider replacing the heated oxygen sensor (Bank 1 Sensor 2) with a new, OEM-quality sensor to ensure proper operation.
Cost to Fix P1137 2001 Ford F150
The typical repair costs for addressing a P1137 code on a 2001 Ford F150 can range from $200 to $500, depending on the specific cause of the issue and the cost of parts and labor. This estimate includes the cost of a new oxygen sensor, any necessary wiring repairs or replacements, and the labor required for diagnosis and repair. Keep in mind that the actual costs may vary based on the location of the repair facility, the make and model of the vehicle, and any additional components that may need attention. It is recommended to obtain quotes from multiple repair shops to compare prices and ensure a competitive rate. Remember that investing in timely repairs can prevent further damage to your vehicle and ensure optimal performance and efficiency.

Frequently Asked Questions about P1137 2001 Ford F150 Code
What does the OBDII code P1137 mean on a 2001 Ford F150?
1. P1137 indicates that the downstream oxygen sensor (Bank 1, Sensor 2) is detecting a lean condition and is not switching properly as expected. 2.
What are the symptoms of a P1137 code on a 2001 Ford F150?
Common symptoms include reduced fuel efficiency, poor engine performance, rough idling, hesitation during acceleration, and the check engine light being illuminated. 3.
What causes the P1137 code to appear on a 2001 Ford F150?
Potential causes include a faulty oxygen sensor, exhaust leaks near the sensor, a failing catalytic converter, damaged wiring or connectors, or issues with the fuel system causing a lean condition. 4.
Which oxygen sensor is affected by the P1137 code on a 2001 Ford F150?
The code refers to the downstream oxygen sensor on Bank 1, which is the side of the engine with cylinder 1. This sensor is located after the catalytic converter. 5.
Can a dirty mass airflow (MAF) sensor cause the P1137 code?
Yes, a dirty or malfunctioning MAF sensor can cause incorrect air-fuel mixture readings, potentially leading to a lean condition and triggering the P1137 code. 6.
How do I diagnose the P1137 code on a 2001 Ford F150?
Start by checking the wiring and connectors for the Bank 1 Sensor 2 oxygen sensor. Inspect for exhaust leaks and test the sensor’s performance. If the sensor is functioning, check for fuel delivery issues or a faulty catalytic converter. 7.
Can I drive my 2001 Ford F150 with the P1137 code?
While the truck may still be drivable, continuing to drive with this code can lead to decreased fuel efficiency, potential engine damage, or harm to the catalytic converter if not addressed promptly. 8.
How do I fix the P1137 code on a 2001 Ford F150?
Repairs may involve replacing the Bank 1 Sensor 2 oxygen sensor, fixing exhaust leaks, cleaning or replacing the MAF sensor, repairing wiring or connectors, or addressing fuel system issues. 9.
How much does it cost to fix the P1137 code on a 2001 Ford F150?
The cost varies depending on the issue. Replacing an oxygen sensor typically costs $150–$300, while repairs for other causes like exhaust leaks or fuel system problems may cost more. 10.
Will clearing the P1137 code fix the problem on my 2001 Ford F150?
Clearing the code will only reset the check engine light temporarily. If the underlying issue is not resolved, the code will return.
