Code P0138 2018 Honda CR-V Description
The P0138 diagnostic trouble code (DTC) in a 2018 Honda CR-V specifically refers to the Secondary Heated Oxygen Sensor 2 Circuit High Voltage. This code indicates that the oxygen sensor located downstream of the catalytic converter is sending a signal to the engine control module (ECM) that is higher than the normal operating range. The oxygen sensor plays a crucial role in monitoring the exhaust gases and providing feedback to the ECM to adjust the air-fuel mixture for optimal combustion.
Common Causes of P0138 2018 Honda CR-V
- Faulty secondary heated oxygen sensor
- Damaged wiring or connectors in the sensor circuit
- Exhaust leaks near the sensor
- Issues with the ECM
- Contaminated or deteriorated fuel
Symptoms of P0138 2018 Honda CR-V
- Decreased fuel efficiency
- Rough idling or stalling
- Hesitation or jerking during acceleration
- Illuminated check engine light
- Failed emissions test
How to Fix P0138 2018 Honda CR-V
- Begin by diagnosing the issue using a scan tool to retrieve the specific trouble code and monitor the oxygen sensor's live data to confirm the high voltage readings.
- Inspect the wiring and connectors in the sensor circuit for any damage, corrosion, or loose connections. Repair or replace as necessary.
- Test the secondary heated oxygen sensor using a multimeter to check for proper voltage output. Replace the sensor if it is faulty.
- Clear the trouble code from the ECM's memory using the scan tool and perform a test drive to ensure the issue has been resolved.
- If the problem persists, further diagnosis may be required to identify any underlying issues with the ECM or other components.
Cost to Fix P0138 2018 Honda CR-V
