The P2035 fault code indicates that there is a problem with the exhaust gas temperature sensor circuit for Bank 2, specifically Sensor 2. This sensor is responsible for measuring the temperature of the exhaust gases and providing crucial information to the engine control unit (ECU) for optimal performance and emissions control.

What are the symptoms of the P2035 code?

When the P2035 fault code is triggered, you may notice:

• The check engine light illuminating on the dashboard.
• Decreased engine performance, such as a lack of power or acceleration.
• Increased exhaust emissions due to improper fuel mixture.
• Potential overheat warnings or changes in exhaust temperature readings.

What causes the P2035 code?

Common causes of the P2035 code include:

• A faulty exhaust gas temperature sensor.
• Damaged wiring or connectors within the sensor circuit.
• Short circuits or open circuits in the wiring harness.
• Exhaust leaks near the sensor location, affecting readings.
• Issues with the ECU or software glitches.

How to fix P2035?

To resolve the P2035 code, follow these steps:

• Inspect the exhaust gas temperature sensor and its wiring for any visible damage.
• Use an OBD-II scanner to confirm the code and check for any additional codes.
• Test the sensor's resistance and voltage output to ensure it's functioning correctly.
• Replace the sensor if found to be faulty.
• Clean any corrosion from connectors and repair any damaged wiring.
• After repairs, clear the codes and take the vehicle for a test drive to ensure the issue is resolved.
