P2035 Code - Exhaust Gas Temperature Sensor Circuit Low Bank 2 Sensor 2
Quick Answer
The P2035 diagnostic trouble code (DTC) indicates a problem with the exhaust gas temperature (EGT) sensor circuit on bank 2 sensor 2 of the vehicle. Common causes include Faulty EGT Sensor: The most common cause of the P2035 code is a malfunctioning EGT sensor on bank 2 sensor 2, Wiring Issues: Corrosion, damage, or loose connections in the wiring harness connecting the EGT sensor to the ECM can trigger this code, ECM Malfunction: A problem with the engine control module (ECM) can also cause the EGT sensor circuit to read low. Severity is Low - monitor the vehicle and repair when practical. The vehicle can usually be driven if no severe symptoms are present, but symptoms should be checked before extended driving.

Code P2035 Description
The P2035 diagnostic trouble code (DTC) indicates a problem with the exhaust gas temperature (EGT) sensor circuit on bank 2 sensor 2 of the vehicle. This sensor is responsible for monitoring the temperature of the exhaust gases after they have passed through the catalytic converter. The EGT sensor provides crucial data to the engine control module (ECM) to optimize fuel mixture and emissions control.
Common Causes of P2035
- Faulty EGT Sensor: The most common cause of the P2035 code is a malfunctioning EGT sensor on bank 2 sensor 2.
- Wiring Issues: Corrosion, damage, or loose connections in the wiring harness connecting the EGT sensor to the ECM can trigger this code.
- ECM Malfunction: A problem with the engine control module (ECM) can also cause the EGT sensor circuit to read low.
- Exhaust System Leak: An exhaust system leak near the EGT sensor can lead to inaccurate temperature readings.
Symptoms of P2035
- Check Engine Light: The most common symptom associated with the P2035 code is the illumination of the check engine light on the vehicle's dashboard.
- Decreased Fuel Efficiency: A malfunctioning EGT sensor can cause the engine to run less efficiently, leading to decreased fuel efficiency.
- Rough Idling: The engine may experience rough idling or hesitation when the EGT sensor circuit is reading low on bank 2 sensor 2.
- Emission Issues: The vehicle may fail an emissions test due to inaccurate readings from the EGT sensor.
How to Fix P2035
- Diagnose the Issue: Use a diagnostic scanner to retrieve the fault code and perform a thorough inspection of the EGT sensor, wiring, and ECM to identify the root cause of the problem.
- Replace the EGT Sensor: If the sensor is faulty, replace it with a new, OEM-quality sensor that is compatible with the vehicle's make and model.
- Repair Wiring: Check the wiring harness for any damage or corrosion and repair or replace any faulty wiring connections.
- Clear Fault Codes: After completing the repair, clear the fault codes from the ECM using a diagnostic scanner to reset the check engine light and monitor the system for any recurring issues.
- Test Drive: Take the vehicle for a test drive to ensure that the check engine light does not reappear and that the engine is running smoothly.
Cost to Fix P2035
The typical repair costs for addressing the P2035 code can vary depending on the specific cause of the issue. In general, the cost of replacing an EGT sensor can range from $100 to $200, including parts and labor. However, if the issue is related to wiring or ECM problems, the repair costs may be higher. Additionally, the diagnosis time and labor rates at auto repair shops can vary, with hourly rates typically ranging from $80 to $150. It's recommended to consult with a local auto repair shop for a more accurate estimate based on the vehicle's make and model.
