This summary uses the existing diagnostic information shown in full below.
This code means there's a problem with the sensor that checks how hot the exhaust is in a specific part of the car. It's like a thermometer for the car's exhaust, and it's not working right.
The P2474 code is triggered when the Engine Control Module (ECM) detects a problem with the exhaust gas temperature sensor circuit for bank 2, sensor 4. This could mean the sensor is reading temperatures that are too high or too low compared to expected values.
Exhaust Gas Temperature (EGT) sensors monitor the temperature of the exhaust gases leaving the engine. Bank 2 refers to the side of the engine opposite bank 1, and sensor 4 is typically located further downstream in the exhaust system. The ECM uses this data to optimize engine performance and emissions. A P2474 code indicates that the sensor's readings are outside the expected range, which can affect engine efficiency and emissions.
• Check Engine Light illuminated
• Reduced engine performance
• Increased emissions
• Faulty exhaust gas temperature sensor
• Damaged or corroded wiring/connectors
• Exhaust leaks affecting sensor readings
Exhaust Gas Temperature (EGT): A measure of the temperature of gases leaving the engine.
Bank 2: The side of the engine opposite bank 1, typically the side without cylinder 1.
• Use an OBD-II scanner to verify the code.
• Inspect the wiring and connectors for damage or corrosion.
• Test the exhaust gas temperature sensor for proper operation.
• Replace the faulty exhaust gas temperature sensor.
• Repair or replace damaged wiring/connectors.
• Fix any exhaust leaks.
• OBD-II scanner
• Multimeter
• Wrench set

Moderate
• Ford F-150
• Chevrolet Silverado
• Dodge Ram
• Regularly inspect exhaust system components.
• Ensure proper maintenance of sensors.
• Address exhaust leaks promptly.
Sensor Issue
• Do not ignore the Check Engine Light.
• Have the vehicle inspected by a professional if you're unsure.
• Regular maintenance can prevent sensor issues.
Check with your vehicle manufacturer for warranty coverage on emissions-related components.
Exhaust gas temperature sensors have been used in vehicles to monitor emissions and engine performance, and issues with these sensors have been common as vehicles age.
Moderate – While the vehicle may still be drivable, it is important to address this issue to maintain engine performance and emissions compliance.
Driving with a malfunctioning exhaust gas temperature sensor can lead to increased emissions, which may not comply with local environmental regulations.
• Engine at operating temperature
• Vehicle stationary or on a lift
The exhaust gas temperature sensor for bank 2 sensor 4 is typically located in the exhaust system, downstream of the catalytic converter on the side of the engine opposite bank 1.
Q: Can I drive with a P2474 code?
A: While you may be able to drive with this code, it is not recommended as it can affect engine performance and emissions.
Q: How do I reset the Check Engine Light after fixing the issue?
A: You can use an OBD-II scanner to clear the code after repairs are made, or the light may turn off automatically after a few driving cycles if the issue is resolved.

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.
