Though it applies to all, the repair mechanism may be different depending upon the manufacturers. OBD error code P2479 means that your vehicle’s PCM also known as the powertrain control module has detected an issue with the exhaust gas temperature sensor bank 1 sensor 2. This issue can be caused by multiple reasons which are listed below.

What causes this problem with the Exhaust Gas Temperature Out of Range Bank 1 Sensor 2?

• EGT bank 1 sensor 2 being faulty
• EGT bank 1 sensor 2 wires or harnesses being open or shorted
• EGT bank 1 sensor 2 poor electrical connection
• A possible exhaust leakage
• Sensor developing excessive particulate matter buildup

1. Powertrain Control Module - If your car’s PCM isn’t functioning properly, you will need to have it replaced as early as possible to avoid any form of engine performance issues. You can find one with us at PartsAvatar for your specific make and model.
2. Exhaust Gas Temperature Sensor - EGT is responsible for warning the driver of situations that are potentially damaging to the engine and in this way it is a really important gauge. So, if you have a damaged one, undergo it’s replacement as soon as possible.
3. Diesel Particulate System & Parts - Keep your diesel particulate system and all the related parts in best of its shape for filtering the harmful carbon particulates produced in the combustion. Get rid of this error code P2479 by replacing the faulty DPF filters and parts.
