P2036 Fault Code

Exhaust Gas Temperature Sensor Circuit High Bank 2 Sensor 2

• What does that mean?
• Symptoms
• Causes
• Solutions

The P2036 fault code indicates a problem with the exhaust gas temperature sensor circuit on Bank 2, specifically for Sensor 2. This sensor is crucial for monitoring the temperature of the exhaust gases, helping to optimize engine performance and emissions control. When the circuit shows high readings, it can lead to poor fuel efficiency and increased emissions.

• Bank 2 refers to the side of the engine that does not contain cylinder 1.
• Sensor 2 is typically located after the catalytic converter in the exhaust system.

What are the symptoms of the P2036 code?

Symptoms associated with the P2036 fault code may include:

• Check Engine Light (CEL) being activated on the dashboard
• Reduced engine performance or efficiency
• Poor fuel economy due to improper fuel management
• Potential overheating of the exhaust system if the sensor is malfunctioning.

What causes the P2036 code?

Common causes for the P2036 code include:

• Faulty exhaust gas temperature sensor
• Wiring issues such as shorts, opens, or corrosion
• Poor electrical connections or damaged connectors
• Exhaust leaks around the sensor that can affect temperature readings
• Malfunctioning engine control module (ECM) that misreads sensor data.

How to fix P2036?

To resolve the P2036 fault code, consider the following steps:

• Inspect the wiring and connectors for damage or corrosion and repair if necessary.
• Test the exhaust gas temperature sensor and replace it if it’s faulty.
• Check for any exhaust leaks around the sensor and repair them to ensure accurate readings.
• Clear the fault code from the ECM and test drive the vehicle to see if it reappears. If it does, further diagnosis may be needed.
