P2033 Dodge Code - Exhaust Gas Temperature Sensor Circuit High Bank 1 Sensor 2
Quick Answer
The P2033 diagnostic trouble code (DTC) for Dodge vehicles refers to the Exhaust Gas Temperature Sensor Circuit High Bank 1 Sensor 2. Common causes include Faulty Sensor: The exhaust gas temperature sensor itself may be malfunctioning, leading to inaccurate temperature readings, Wiring Issues: Damaged or corroded wiring connections to the sensor can cause a high voltage signal to be sent to the ECM or PCM, Exhaust System Problems: Issues such as exhaust leaks or blockages can affect the sensor's readings and trigger the P2033 code. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P2033 Dodge Description
The P2033 diagnostic trouble code (DTC) for Dodge vehicles refers to the Exhaust Gas Temperature Sensor Circuit High Bank 1 Sensor 2. This code indicates that there is a problem with the exhaust gas temperature sensor in the second sensor of bank 1 in the vehicle's exhaust system. The exhaust gas temperature sensor is responsible for monitoring the temperature of the exhaust gases leaving the engine and transmitting this information to the engine control module (ECM) or powertrain control module (PCM). This data is crucial for the engine management system to adjust fuel injection timing and other parameters to optimize engine performance and emissions.
Common Causes of P2033 Dodge
- Faulty Sensor: The exhaust gas temperature sensor itself may be malfunctioning, leading to inaccurate temperature readings.
- Wiring Issues: Damaged or corroded wiring connections to the sensor can cause a high voltage signal to be sent to the ECM or PCM.
- Exhaust System Problems: Issues such as exhaust leaks or blockages can affect the sensor's readings and trigger the P2033 code.
- ECM or PCM Malfunction: A problem with the engine control module or powertrain control module can also lead to erroneous sensor readings.
Symptoms of P2033 Dodge
- Check Engine Light: The most common symptom associated with the P2033 code is the illumination of the check engine light on the vehicle's dashboard.
- Reduced Engine Performance: The vehicle may experience a decrease in engine power or responsiveness due to incorrect fuel injection timing caused by the faulty sensor reading.
- Poor Fuel Economy: A malfunctioning exhaust gas temperature sensor can lead to inefficient fuel combustion, resulting in decreased fuel efficiency.
- Increased Emissions: The vehicle may produce higher emissions than normal due to improper engine management resulting from the faulty sensor signal.
How to Fix P2033 Dodge
- Diagnose the Issue: Use a scan tool to retrieve the specific DTC and pinpoint the exact cause of the problem.
- Inspect Sensor and Wiring: Check the exhaust gas temperature sensor and its wiring for any visible damage or corrosion.
- Replace Sensor: If the sensor is found to be faulty, replace it with a new, OEM-quality sensor.
- Repair Wiring: Repair or replace any damaged wiring connections to ensure proper signal transmission.
- Clear Codes and Test Drive: Clear the DTC from the ECM or PCM memory, and test drive the vehicle to confirm that the issue has been resolved.
Cost to Fix P2033 Dodge
The typical repair costs for addressing the P2033 code on a Dodge vehicle can vary depending on the specific model and year of the vehicle, the location of the repair shop, and the type of engine. Generally, replacing the exhaust gas temperature sensor and repairing any wiring issues can range from $150 to $300 for parts and labor. However, it's important to note that diagnosis time and labor rates can vary significantly between different auto repair shops. It's recommended to contact local shops for a more accurate estimate based on your particular circumstances.
