P0137 1999 Honda Civic Code - O2 Sensor Circuit Low Voltage Bank 1 Sensor 2
Quick Answer
The P0137 diagnostic trouble code (DTC) for a 1999 Honda Civic indicates that the oxygen sensor circuit has low voltage for Bank 1 Sensor 2. Common causes include Faulty oxygen sensor: The most common cause of a low voltage O2 sensor circuit is a malfunctioning sensor itself, Wiring issues: Damaged or corroded wiring connections can disrupt the signal from the oxygen sensor to the ECM, Exhaust leaks: Leaks in the exhaust system can introduce false air into the system, affecting the oxygen sensor readings. Severity is Moderate - service should be scheduled soon. The vehicle may still be drivable for short trips if it runs normally, but avoid hard driving and repair it soon.

Code P0137 1999 Honda Civic Description
The P0137 diagnostic trouble code (DTC) for a 1999 Honda Civic indicates that the oxygen sensor circuit has low voltage for Bank 1 Sensor 2. This sensor is a crucial component of the vehicle's emissions control system, responsible for monitoring the oxygen levels in the exhaust gases to ensure proper fuel mixture and combustion efficiency. Bank 1 refers to the side of the engine where the number 1 cylinder is located, while Sensor 2 denotes the downstream sensor located after the catalytic converter.
Common Causes of P0137 1999 Honda Civic
- Faulty oxygen sensor: The most common cause of a low voltage O2 sensor circuit is a malfunctioning sensor itself.
- Wiring issues: Damaged or corroded wiring connections can disrupt the signal from the oxygen sensor to the ECM.
- Exhaust leaks: Leaks in the exhaust system can introduce false air into the system, affecting the oxygen sensor readings.
- Exhaust system damage: Physical damage to the exhaust system, such as a damaged catalytic converter, can impact the sensor's performance.
- ECM failure: In rare cases, a malfunctioning engine control module (ECM) can cause issues with the oxygen sensor circuit.
Symptoms of P0137 1999 Honda Civic
- Decreased fuel efficiency: A malfunctioning oxygen sensor can cause the engine to run rich or lean, leading to decreased fuel efficiency.
- Rough idle: The engine may experience rough idling or hesitation due to incorrect fuel mixture.
- Check Engine Light: The illumination of the Check Engine Light is often the first indication of an issue with the O2 sensor.
- Increased emissions: A faulty oxygen sensor can cause the vehicle to emit higher levels of harmful pollutants, which may lead to failed emissions tests.
How to Fix P0137 1999 Honda Civic
- Diagnostic scan: Use an OBD-II scanner to retrieve the specific trouble code and confirm the issue with the O2 sensor.
- Inspect wiring: Check the wiring harness and connections for any damage or corrosion that may be affecting the sensor's signal.
- Replace oxygen sensor: If the sensor is faulty, replace it with a new one that meets the manufacturer's specifications.
- Clear codes: After repairing the issue, clear the trouble codes from the ECM to reset the Check Engine Light.
- Test drive: Take the vehicle for a test drive to ensure that the repair has resolved the low voltage issue with the O2 sensor.
Cost to Fix P0137 1999 Honda Civic
The typical repair costs for addressing a P0137 code on a 1999 Honda Civic can range from $150 to $300, including parts and labor. However, the actual cost may vary depending on the location, dealership rates, and the specific diagnostic time required. It is advisable to consult with a trusted auto repair shop for a more accurate estimate based on your vehicle's make and model.
