Code P0137 Acura Description
The P0137 code for Acura vehicles specifically refers to an issue with the Secondary Heated Oxygen Sensor 2 Circuit Low Voltage. The oxygen sensor, also known as the O2 sensor, is a crucial component of the vehicle's emissions control system. It measures the amount of oxygen in the exhaust gases and sends this information to the engine control module (ECM) to adjust the air-fuel mixture for optimal combustion. The Secondary Heated Oxygen Sensor 2 is located downstream of the catalytic converter and is responsible for monitoring the efficiency of the converter in reducing harmful emissions.
Common Causes of P0137 Acura
- Faulty oxygen sensor: The sensor itself may be malfunctioning and providing incorrect voltage readings.
- Wiring issues: Damaged or corroded wiring connecting the sensor to the ECM can disrupt the signal.
- Exhaust leaks: Leaks in the exhaust system can affect the sensor's readings.
- Catalytic converter problems: A failing catalytic converter can impact the sensor's performance.
- ECM issues: Rarely, a problem with the engine control module could be the cause of the low voltage signal.
Symptoms of P0137 Acura
- Decreased fuel efficiency: A faulty oxygen sensor can cause the engine to run rich or lean, leading to increased fuel consumption.
- Check Engine Light: The P0137 code will trigger the check engine light on the dashboard.
- Rough idling or stalling: Incorrect air-fuel mixture can result in rough idling or even engine stalling.
- Poor acceleration: The vehicle may experience hesitation or lack of power during acceleration.
- Emissions test failure: A malfunctioning oxygen sensor can cause the vehicle to fail emissions tests.
How to Fix P0137 Acura
- Diagnostic scan: Use an OBD-II scanner to retrieve the specific fault code and confirm the issue.
- Inspect oxygen sensor: Check the Secondary Heated Oxygen Sensor 2 for any visible damage or signs of wear.
- Check wiring: Inspect the wiring harness for any breaks, corrosion, or loose connections.
- Test catalytic converter: Verify the functionality of the catalytic converter to rule out any related issues.
- Replace sensor: If the oxygen sensor is faulty, replace it with a new one and reset the ECM to clear the code.
Cost to Fix P0137 Acura
The cost of repairing a P0137 code on an Acura vehicle can vary depending on the specific model and the extent of the issue. Typically, the price for a new oxygen sensor ranges from $50 to $200, depending on the brand and quality. Labor costs can add another $100 to $200, considering the time needed for diagnosis and replacement. Overall, the total repair cost for this issue may fall between $150 and $400, but it's advisable to get a personalized quote from a certified mechanic.
