P2429 Ford Code - Exhaust Gas Temperature Too High Bank 2

P2429 indicates "Exhaust Gas Temperature Too High Bank 2," meaning the exhaust gas temperature sensor on Bank 2 has detected temperatures exceeding normal operating limits.

Common symptoms include reduced engine performance, poor fuel efficiency, excessive exhaust heat, and the check engine light being illuminated.

Potential causes include a faulty exhaust gas temperature sensor, a clogged catalytic converter, excessive fuel delivery, or issues with the turbocharger (if equipped).

Diagnosis involves using an OBDII scanner to confirm the code, inspecting the exhaust gas temperature sensor and wiring, checking for exhaust restrictions, and verifying proper fuel system operation.

Driving with this code is not recommended, as excessive exhaust temperatures can damage the catalytic converter or other components in the exhaust system.

Repairs may include replacing a faulty exhaust gas temperature sensor, cleaning or replacing a clogged catalytic converter, addressing fuel system issues, or repairing damaged wiring.

Costs vary but typically range from $100 to $300 for sensor replacement. Catalytic converter repairs can cost significantly more, depending on the vehicle model.

Bank 2 refers to the side of the engine opposite Bank 1, typically the side without cylinder 1, depending on the engine configuration.

While uncommon, a severely clogged air filter can contribute to excessive exhaust temperatures by affecting air-fuel mixture and engine performance.

No, the sensor may be accurately reporting a problem. Further diagnosis is needed to rule out other causes like a clogged catalytic converter or engine running too rich.
