P2428 Dodge Code - Exhaust Gas Temperature Too High Bank 1

Code P2428 indicates that the exhaust gas temperature in Bank 1 is too high, which may trigger the powertrain control module (PCM) to take protective measures.

Symptoms include reduced engine performance, poor fuel economy, excessive engine heat, and the illumination of the check engine light.

Common causes include a faulty exhaust gas temperature sensor, restricted exhaust flow, a clogged catalytic converter, or excessive fuel delivery leading to rich combustion.

Yes, a malfunctioning sensor can provide incorrect readings to the PCM, causing this code to appear.

Use an OBD-II scanner to confirm the code, inspect the exhaust gas temperature sensor and wiring for damage, check for restricted exhaust flow, and test the catalytic converter for clogging.

While the vehicle may still be drivable, prolonged operation with this code can cause engine damage or catalytic converter failure due to excessive heat.

Repairs may include replacing the exhaust gas temperature sensor, cleaning or replacing the catalytic converter, inspecting and repairing exhaust blockages, and checking the fuel system for issues.

A clogged or failing catalytic converter can restrict exhaust flow, increasing temperature in the exhaust system and triggering this code.

Yes, damaged or shorted wiring for the exhaust gas temperature sensor can lead to incorrect readings and activation of this code.

Clearing the code may temporarily turn off the check engine light, but the underlying issue must be diagnosed and repaired to prevent the code from returning.
