The Engine Fault Code P2035 refers to a problem with the exhaust gas temperature (EGT) sensor circuit for Bank 2, Sensor 2. This code is often related to the sensors that monitor the temperature of the exhaust gases coming out of the engine, which helps the engine control module (ECM) manage emissions and performance.
What It Means:
1. Exhaust Gas Temperature Sensor: This sensor measures the temperature of the exhaust gases. It helps in monitoring the efficiency of the catalytic converter and ensures that the engine is running optimally.
2. Bank 2: This indicates the side of the engine that contains cylinder 2. In a V-type engine, Bank 1 is typically the side with the first cylinder, while Bank 2 is the opposite side.
3. Sensor 2: This usually refers to the second sensor in the exhaust system, which is typically located after the catalytic converter.
Possible Causes:
– A faulty exhaust gas temperature sensor.
– Damaged wiring or connectors in the sensor circuit.
– A problem with the ECM.
– Exhaust leaks affecting sensor readings.
Alternative Meanings by Manufacturer:
While P2035 generally has the same meaning across different manufacturers, there may be slight variations in how it`s interpreted or how the systems are set up. Here are some examples:
1. Porsche: The code may indicate issues with the EGT sensor in relation to the turbocharger system, especially in models with turbocharged engines.
2. Mini: Similar to BMW, where the EGT sensor`s performance can affect the vehicle`s emissions system and overall engine management.
3. Mercedes: The code might relate to the emissions control system, particularly in models with complex exhaust setups like BlueTEC diesel engines.
4. Audi: Audi models may have additional diagnostic features that could provide more specific information about the sensor`s performance.
5. Jaguar and Land Rover: They may interpret this code in the context of their unique engine management systems, which can differ significantly from other manufacturers.
What to Do:

4. Open Circuit: If the circuit is broken somewhere, it can also lead to a low reading.
5. Exhaust Leaks: Leaks near the sensor can affect the readings and cause errors.
6. ECU Problems: In rare cases, the engine control unit itself might be malfunctioning and misinterpreting signals.
Manufacturer-Specific Differences
1. Porsche: Porsche models may have more complex exhaust systems with multiple sensors. If Bank 2 is not easily accessible, it might require more extensive labor to diagnose and replace the sensor.
2. Mini: Mini models often have compact engine bays, which could lead to overheating of sensors. Check for heat damage around the EGT sensor area.
3. Mercedes-Benz: Mercedes vehicles might have additional components, like turbochargers, that can affect exhaust temperatures. Always check for related issues in the turbo system.
4. Audi: Audi models often use multiple EGT sensors. Make sure to identify which sensor corresponds to Bank 2, Sensor 2, as the layout can vary by model.
5. Jaguar: Jaguar vehicles may have more sophisticated engine management systems. If you see this code, it might also be worth checking for software updates or recalls related to the engine management.
6. Land Rover: Land Rover models can have unique exhaust configurations, especially in diesel variants. Be sure to check for specific issues related to the diesel exhaust system if applicable.
Conclusion
If you encounter the P2035 code, it`s advisable to start with a visual inspection of the wiring and connectors, then test the sensor itself. If everything looks good but the code persists, you may need to delve deeper into the ECU or other related systems. Always refer to the specific service manual for your vehicle for the best guidance.
Fixing the Engine Fault Code P2035, which relates to the Exhaust Gas Temperature (EGT) Sensor Circuit Low for Bank 2 Sensor 2, involves a few steps. This code is common across various manufacturers, including Porsche, Mini, Mercedes, Audi, Jaguar, and Land Rover. Heres how to approach the issue:
Step 1: Understand the Code
– P2035 indicates a problem with the EGT sensor circuit. Bank 2 usually refers to the side of the engine opposite Bank 1. Sensor 2 is typically located downstream in the exhaust system.
Step 2: Check the EGT Sensor
– Inspection: Visually inspect the EGT sensor and its wiring. Look for any damage, corrosion, or loose connections.
– Testing: Use a multimeter to test the sensor`s resistance. Compare your readings to the manufacturer`s specifications. If the resistance is out of range, the sensor may need replacement.
Step 3: Check Wiring and Connectors
– Wiring: Inspect the wiring harness for frays or breaks. Damaged wires can cause low voltage readings.
– Connectors: Ensure that connectors are clean and secure. Corrosion can lead to poor connections.
Step 4: Check for Exhaust Leaks
