This summary uses the existing diagnostic information shown in full below.
This code means that the car's computer thinks the temperature sensor in the exhaust is reading too high on one side of the engine.
The P2033 code is triggered when the powertrain control module (PCM) detects a high voltage signal from the exhaust gas temperature sensor on bank 1, sensor 2.
The exhaust gas temperature (EGT) sensor monitors the temperature of the exhaust gases exiting the engine. This information is used by the PCM to optimize engine performance and emissions. A high circuit signal indicates that the sensor is reporting a temperature that is too high, which may be due to a faulty sensor, wiring issues, or actual high exhaust temperatures.
• Check Engine Light illuminated
• Possible decrease in fuel efficiency
• Potential engine performance issues
• Faulty exhaust gas temperature sensor
• Wiring issues or poor connections in the sensor circuit
• Exhaust system issues causing high temperatures
PCM: Powertrain Control Module
EGT: Exhaust Gas Temperature
• Use an OBD-II scanner to confirm the code.
• Inspect the exhaust gas temperature sensor and wiring for damage.
• Test the sensor's resistance and compare with specifications.
• Replace the faulty exhaust gas temperature sensor.
• Repair or replace damaged wiring or connectors.
• Inspect and repair any exhaust system issues.
• OBD-II scanner
• Multimeter
• Basic hand tools
$100 - $300
Moderate
• Ford F-150
• Chevrolet Silverado
• Dodge Ram
• Regular maintenance of the exhaust system.
• Periodically check and clean sensors.
• Ensure proper engine tuning and fuel quality.
Sensor Issue
• Do not ignore the Check Engine Light.
• Have the vehicle inspected by a professional if unsure.
• Monitor fuel efficiency for any changes.
Check vehicle warranty for coverage on emissions-related components.
This code has been commonly associated with diesel engines and vehicles with advanced emissions systems.
Moderate – It should be addressed soon to prevent potential engine performance issues.
Driving with a faulty exhaust gas temperature sensor can lead to increased emissions and may not comply with local emissions regulations.
• Engine running at operating temperature
• Vehicle in motion
The exhaust gas temperature sensor is typically located in the exhaust system, downstream of the catalytic converter on bank 1.
Q: Can I drive with a P2033 code?
A: While you may be able to drive, it's best to address the issue soon to avoid potential engine damage or increased emissions.
Q: How do I clear a P2033 code?
A: After repairs, use an OBD-II scanner to clear the code from the vehicle's computer.

Fitment Required · Vehicle-fitment part
Relevant when catalyst-efficiency or emissions faults persist after proper diagnosis.
Catalyst-efficiency faults sometimes point toward converter problems after proper testing.
Catalytic converters are highly vehicle-specific and should not be purchased by code alone.
View options on AmazonThese parts may be related to this fault category, but a code by itself does not confirm exact fitment or guarantee that replacing a part will solve the problem.
