Code P1137 Pontiac Description
The P1137 code for Pontiac vehicles indicates an issue with the HO2S (Heated Oxygen Sensor) Bank 1 Sensor 2, specifically pointing to a lean air-fuel mixture or low voltage condition. This sensor is responsible for monitoring the oxygen levels in the exhaust gases after they have passed through the catalytic converter. The information provided by this sensor is crucial for the engine control module (ECM) to adjust the air-fuel ratio for optimal combustion efficiency.
Common Causes of P1137 Pontiac
- Faulty HO2S Bank 1 Sensor 2
- Vacuum leaks in the intake system
- Fuel pressure regulator issues
- Exhaust leaks near the sensor
- Wiring or connector problems in the sensor circuit
Symptoms of P1137 Pontiac
- Decreased fuel efficiency
- Rough idling or stalling
- Engine misfires
- Check Engine Light illuminated
- Reduced engine performance
How to Fix P1137 Pontiac
- Use an OBD-II scanner to read and clear the code to determine if it reoccurs.
- Inspect the HO2S Bank 1 Sensor 2 and its wiring for any visible damage or corrosion.
- Test the sensor using a multimeter to check for proper voltage output.
- Replace the HO2S Bank 1 Sensor 2 if it is faulty or not functioning within specifications.
- Clear the code and test drive the vehicle to ensure the issue has been resolved.
Cost to Fix P1137 Pontiac
The typical repair costs for addressing a P1137 code on a Pontiac vehicle can range from $150 to $300, including the cost of the oxygen sensor itself and labor charges. Keep in mind that the actual cost can vary depending on the specific make and model of the vehicle, the location of the repair, and any additional parts or services that may be required. It is recommended to consult with a qualified mechanic or auto repair shop for a more accurate estimate based on your individual circumstances.

Frequently Asked Questions about P1137 Pontiac Code
1. What does the OBDII code P1137 mean for a Pontiac?
P1137 indicates that the downstream oxygen sensor (Bank 1, Sensor 2) is detecting a lean condition or low voltage output, which may affect the vehicle's emissions and efficiency.
2. What are the common symptoms of a P1137 code in a Pontiac?
Symptoms may include the check engine light turning on, reduced fuel efficiency, rough idling, poor engine performance, or failed emissions testing.
3. What causes the P1137 code to appear on a Pontiac?
Possible causes include a faulty oxygen sensor, exhaust leaks, damaged wiring or connectors, fuel system issues, or a malfunctioning catalytic converter.
4. Which oxygen sensor is involved in the P1137 code?
The P1137 code refers to the downstream oxygen sensor (Sensor 2) on Bank 1, which monitors the efficiency of the catalytic converter.
5. Can I drive my Pontiac with a P1137 code?
While it may be possible to drive with this code, it's not recommended as it could lead to increased emissions, reduced fuel efficiency, and potential long-term damage to the catalytic converter.
6. How do I diagnose the P1137 code on my Pontiac?
Start by inspecting the wiring and connectors for the downstream oxygen sensor, checking for exhaust leaks, and testing the sensor's voltage output. A scan tool can also help assess live data and identify related issues.
7. How do I fix the P1137 code on a Pontiac?
Common fixes include replacing the faulty oxygen sensor, repairing damaged wiring or connectors, fixing exhaust leaks, or addressing any underlying fuel system or catalytic converter problems.
8. How much does it cost to repair a P1137 code on a Pontiac?
The cost can vary, but replacing a downstream oxygen sensor typically ranges from $150 to $300, including parts and labor. Additional repairs, such as fixing exhaust leaks, may increase the cost.
9. Can a bad catalytic converter trigger a P1137 code?
Yes, a malfunctioning catalytic converter can cause the downstream oxygen sensor to detect improper exhaust gas levels, triggering the P1137 code.
10. Will clearing the P1137 code solve the problem?
Clearing the code may turn off the check engine light temporarily, but it won't fix the underlying issue. Proper diagnosis and repair are needed to resolve the problem fully.
