Code P1137 Suzuki Description
The P1137 Suzuki code indicates a problem with the HO2S (Heated Oxygen Sensor) circuit's low voltage during power enrichment for Sensor 2. The oxygen sensor is responsible for monitoring the amount of oxygen in the exhaust gases and sending this information to the engine control module (ECM). Sensor 2 is typically located downstream of the catalytic converter and helps to determine how efficiently the catalytic converter is functioning.
Common Causes of P1137 Suzuki
- Faulty oxygen sensor
- Wiring or connector issues
- Vacuum leak
- Clogged fuel injector
- Faulty fuel pressure regulator
Symptoms of P1137 Suzuki
- Decreased fuel efficiency
- Rough idling or stalling
- Engine hesitation or misfiring
- Illuminated Check Engine Light
- Failed emissions test
How to Fix P1137 Suzuki
- Use an OBD-II scanner to retrieve the specific trouble code and confirm the issue.
- Inspect the oxygen sensor and its wiring for any damage or corrosion. Replace the sensor if necessary.
- Check for vacuum leaks and repair any damaged hoses or gaskets.
- Test the fuel injectors and fuel pressure regulator for proper operation.
- Clear the trouble code and test drive the vehicle to ensure the issue is resolved.
Cost to Fix P1137 Suzuki
