This summary uses the existing diagnostic information shown in full below.
This code means that a sensor in your car's exhaust system is detecting temperatures that are too high. It's like a thermometer for the car's exhaust, and it's saying the temperature is hotter than it should be.
The P2469 code is triggered when the vehicle's powertrain control module (PCM) detects a high voltage signal from the exhaust gas temperature sensor located on bank 2, sensor 3. This indicates that the exhaust temperature is higher than expected.
The exhaust gas temperature sensor is a thermistor that changes its resistance with temperature. The PCM uses this sensor to monitor the temperature of the exhaust gases. If the sensor output voltage is higher than the specified range, the PCM sets the P2469 code.
• Check Engine Light is on
• Possible decrease in fuel efficiency
• Potential engine performance issues
• Faulty exhaust gas temperature sensor
• Wiring issues such as open or short circuits
• Excessive exhaust temperatures due to engine issues
PCM: Powertrain Control Module, the computer that controls engine and transmission functions.
Thermistor: A type of resistor whose resistance varies significantly with temperature.
• Use an OBD-II scanner to confirm the code.
• Inspect the wiring and connectors for damage.
• Test the exhaust gas temperature sensor for proper operation.
• Replace the faulty exhaust gas temperature sensor.
• Repair or replace damaged wiring or connectors.
• Address any underlying engine issues causing high exhaust temperatures.
• OBD-II scanner
• Multimeter
• Basic hand tools

Moderate
• Ford F-150
• Chevrolet Silverado
• Toyota Tacoma
• Regular maintenance and inspection of exhaust components
• Ensure proper engine tuning
• Avoid excessive idling
Sensor Issue
• Do not ignore the Check Engine Light.
• Have the vehicle inspected by a professional if unsure.
• Monitor for any changes in vehicle performance.
Check your vehicle's warranty coverage for sensor-related repairs.
The P2469 code has been associated with vehicles experiencing sensor failures due to prolonged exposure to high exhaust temperatures.
Moderate – While not immediately critical, it should be addressed to prevent potential engine damage.
Driving with a malfunctioning sensor can lead to increased emissions and potential engine damage.
• Engine at normal operating temperature
• Vehicle in a safe, stationary position
The exhaust gas temperature sensor is located on the exhaust manifold or exhaust pipe of bank 2, downstream of the catalytic converter.
Q: Can I drive with a P2469 code?
A: It's not recommended to drive for extended periods with this code, as it can lead to engine damage or increased emissions.
Q: How can I reset the P2469 code?
A: You can clear the code with an OBD-II scanner, but it's important to fix the underlying issue first.

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.
