This summary uses the existing diagnostic information shown in full below.
This code means that a sensor in the car that checks how hot the exhaust gases are is showing a higher temperature than it should. It's like a thermometer that is saying it's really hot when it shouldn't be.
This code indicates that the exhaust gas temperature sensor on bank 1, sensor 6, is reading a voltage that is higher than the expected range.
The P2EA2 code is triggered when the Powertrain Control Module (PCM) detects a high voltage signal from the exhaust gas temperature sensor located on bank 1, sensor 6. This sensor is responsible for monitoring the temperature of the exhaust gases to ensure optimal engine performance and emissions control.
• Check Engine Light is on
• Poor fuel economy
• Possible reduced engine performance
• Faulty exhaust gas temperature sensor
• Wiring issues such as short circuits or open circuits
• Connector problems like corrosion or loose connections
PCM: Powertrain Control Module
OBD-II: On-Board Diagnostics, Second Generation
• Use an OBD-II scanner to confirm the code.
• Inspect the exhaust gas temperature sensor and its wiring for damage.
• Test the sensor's resistance and voltage output.
• Replace the faulty exhaust gas temperature sensor.
• Repair or replace damaged wiring or connectors.
• Clear the code and test drive the vehicle to ensure the issue is resolved.
• OBD-II scanner
• Multimeter
• Socket set

Moderate
• Ford F-150
• Chevrolet Silverado
• Toyota Tundra
• Regular maintenance checks on sensors and wiring.
• Ensure proper exhaust system operation.
• Avoid harsh driving conditions that may damage sensors.
Sensor Issue
• Do not ignore the Check Engine Light; have it checked promptly.
• Consider regular diagnostic checks to catch issues early.
Sensor-related repairs may be covered under the vehicle's emissions warranty.
Exhaust gas temperature sensors have been used for many years to help control emissions and engine performance. Issues with these sensors can lead to increased emissions and decreased fuel efficiency.
Moderate – While it may not immediately affect drivability, it can lead to increased emissions and potential engine performance issues if not addressed.
Ignoring emissions-related codes can lead to failing emissions tests and potential fines in areas with strict emissions regulations.
• Engine at normal operating temperature
• Vehicle in a safe, stationary position
The exhaust gas temperature sensor is typically located in the exhaust system, often near the exhaust manifold or turbocharger, on the side of the engine labeled as bank 1.
Q: Can I drive with a P2EA2 code?
A: While you can drive with this code, it's not recommended to ignore it as it may lead to increased emissions and potential engine performance issues.
Q: How do I know if the sensor is faulty?
A: A diagnostic test using an OBD-II scanner and a multimeter can help determine if the sensor is faulty.
