p016e oxygen sensor circuit slow response bank 2 sensor 2
P016E Oxygen Sensor Circuit Slow Response Bank 2 Sensor 2
Definition: The OBD-II code P016E indicates that the oxygen sensor circuit for bank 2, sensor 2 is responding slower than expected. This sensor monitors the efficiency of the catalytic converter on bank 2 by measuring the amount of oxygen in the exhaust gases.
p016e – Oxygen Sensor Circuit Slow Response Bank 2 Sensor 2
Typical Severity: Moderate
Common Causes
p016e – Oxygen Sensor Circuit Slow Response Bank 2 Sensor 2
Common causes of this OBD2 code include:
- Faulty oxygen sensor
- Wiring issues in the oxygen sensor circuit
- Exhaust leaks near the sensor
- Engine running rich or lean causing incorrect readings
Common Misdiagnosis
OBD2 Code: P016E
Description: Oxygen Sensor Circuit Slow Response Bank 2 Sensor 2
Common Misdiagnosis: Replacing the oxygen sensor without checking for exhaust leaks, wiring issues, or other underlying problems that may cause a slow response.
Common Diagnostic Steps
OBD2 Code: P016E
Description: Oxygen Sensor Circuit Slow Response Bank 2 Sensor 2
- Inspect the wiring and connectors for damage or corrosion.
- Check for exhaust leaks near the sensor that could affect readings.
- Test the oxygen sensor’s voltage and response time using a multimeter.
- Verify proper operation of the engine control module (ECM).
- Examine fuel system components for issues affecting air-fuel mixture.
- Replace the oxygen sensor if it fails diagnostic tests.
