Code P1137 1997 Ford F150 Description
The P1137 code in a 1997 Ford F150 indicates a lack of heated oxygen sensor switches on Bank 1 Sensor 2, with the switch indicating a lean air-fuel mixture. This essentially means that the oxygen sensor in the exhaust system after the catalytic converter is not functioning properly or is not providing accurate readings to the engine control module (ECM). The ECM uses these readings to adjust the air-fuel mixture for optimal combustion and emission control. When the sensor indicates a lean condition, it means there is too much oxygen in the exhaust compared to the amount of fuel, which can lead to poor engine performance, decreased fuel efficiency, and increased emissions.
Common Causes of P1137 1997 Ford F150
- Faulty oxygen sensor
- Contaminated oxygen sensor
- Wiring or connector issues
- Exhaust leak near sensor
- ECM software or hardware issues
Symptoms of P1137 1997 Ford F150
- Poor engine performance
- Decreased fuel efficiency
- Rough idle or hesitation during acceleration
- Check Engine Light illuminated
- Increased emissions
How to Fix P1137 1997 Ford F150
- Diagnose the issue by scanning the vehicle for trouble codes and inspecting the oxygen sensor and related components.
- Replace the Bank 1 Sensor 2 oxygen sensor if it is faulty or contaminated.
- Repair any wiring or connector issues leading to the sensor.
- Check for and repair any exhaust leaks near the sensor.
- Clear the trouble codes and test drive the vehicle to ensure the issue has been resolved.
Cost to Fix P1137 1997 Ford F150
The typical repair costs for addressing a P1137 code in a 1997 Ford F150 can range from $150 to $400, including parts and labor. However, the specific diagnosis time and labor rates at auto repair shops can vary based on factors such as location, vehicle make and model, and engine type.

Frequently Asked Questions about P1137 1997 Ford F150 Code
1. What does the OBDII code P1137 mean on a 1997 Ford F150?
P1137 indicates that the oxygen sensor on Bank 1, Sensor 2 (downstream of the catalytic converter), is detecting a lean condition and isn't switching as expected.
2. What are the symptoms of code P1137 in a 1997 Ford F150?
Common symptoms include decreased fuel efficiency, rough idling, hesitation during acceleration, and the check engine light being illuminated.
3. What causes the P1137 code on a 1997 Ford F150?
Possible causes include a faulty oxygen sensor, exhaust leaks, air intake leaks, failing catalytic converter, or issues with the fuel system like low fuel pressure or a clogged fuel filter.
4. Can a bad oxygen sensor cause the P1137 code?
Yes, a faulty or failing heated oxygen sensor (Bank 1, Sensor 2) is a common cause of the P1137 code.
5. How do I diagnose the P1137 code on a 1997 Ford F150?
Start by inspecting the oxygen sensor and wiring for damage. Check for exhaust or intake leaks, test fuel pressure, and use a scan tool to monitor oxygen sensor readings.
6. Can a vacuum leak trigger the P1137 code on a Ford F150?
Yes, a vacuum leak can cause a lean condition, which might lead to the P1137 code being triggered.
7. How do I fix the P1137 code on a 1997 Ford F150?
Repairs may include replacing the faulty oxygen sensor, repairing exhaust or intake leaks, cleaning or replacing the fuel injectors, or addressing fuel pressure issues.
8. Is it safe to drive with the P1137 code on a 1997 Ford F150?
While the vehicle may still be drivable, ignoring the P1137 code can lead to poor fuel economy, reduced performance, and potential damage to the catalytic converter over time.
9. How much does it cost to fix the P1137 code on a 1997 Ford F150?
Repair costs vary, with oxygen sensor replacement typically costing $100–$300, while fixing leaks or fuel system issues may cost more depending on the severity.
10. Can cleaning the oxygen sensor fix the P1137 code?
Cleaning rarely resolves oxygen sensor problems. If the sensor is faulty, replacing it is usually the best solution.
