P2478: Your Car’s Dpf Pressure Sensor Needs Attention
The P2478 code is related to the Exhaust Gas Temperature Sensor (EGTS). The EGTS detects exhaust gas temperature and converts it into a voltage. The PCM sets the P2478 OBDII code when the EGTS is out of factory specifications.
This code indicates that the exhaust gas temperature is out of range for Bank 1 Sensor 1. The EGTS is located in front of the Diesel Oxidation Catalyst (DOC) andor in front of the Diesel Particulate Filter (DPF). The PCM continuously monitors the EGTS for proper circuit continuity and out of range high values.
Reducing emissions is the main purpose of the EGTS and the P2478 code alerts the driver to a potential issue with this system.
FAQ
If you see the engine light on or service engine soon warning light, it could be due to the P2478 fault code. This code is usually caused by a faulty Exhaust Gas Temperature Sensor (EGTS) Bank 1 Sensor 1, an open or shorted harness, poor electrical connection, exhaust leaks, or excessive particulate matter buildup on the sensor. To fix this issue, you should check the possible causes listed above, visually inspect the related wiring harness and connectors, and look for damaged components or broken, bent, pushed out, or corroded connector’s pins.
If you’re experiencing an Engine Light ON (or Service Engine Soon Warning Light) due to the P2478 fault code, you may need to visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector’s pins. This could be caused by a faulty Exhaust Gas Temperature Sensor (EGTS) Bank 1 Sensor 1, an open or shorted Exhaust Gas Temperature Sensor Bank 1 Sensor 1 harness, a poor electrical connection in the Exhaust Gas Temperature Sensor Bank 1 Sensor 1 circuit, exhaust leaks, or excessive particulate matter buildup on the sensor.
Ignoring the P2478 fault code, caused by a faulty Exhaust Gas Temperature Sensor (EGTS) Bank 1 Sensor 1, can lead to serious consequences. The Engine Light or Service Engine Soon Warning Light will remain on, indicating a problem with the vehicle’s emissions system. This can result in decreased fuel efficiency, increased emissions, and potential damage to the engine or catalytic converter. It is important to check the possible causes and visually inspect the related wiring harness and connectors to avoid further damage.
Wrap Up
If your engine light is on, it could be due to a faulty Exhaust Gas Temperature Sensor (EGTS) Bank 1 Sensor 1, an open or shorted harness, poor electrical connection, exhaust leaks, or excessive particulate matter buildup.
