P2480 OBD Error Code: Problem & Solutions

<<See All OBD Codes

The trouble code P2480 can be explained as Exhaust Gas Temperature Sensor Circuit/Open Bank 1 Sensor 5. This diagnostic fault code is a generic powertrain code, which means that it would apply to the OBD-II equipped vehicles. The specific repair steps can vary as it depends upon the vehicle make and model. The engine control module, powertrain control module or the transmission control module monitors this circuit depending upon the particular automobile.

The EGT sensor is responsible for reading the temperature of the exhaust, sending this information back to the ECU, which will then use the information to properly control the exhaust after-treatment system reducing harmful emissions. When an EGT sensor fails and the readings become too high or non-existent, this leads to a compromised after-treatment system. Thus, whenever there’s a problem with the performance of the EGT sensor for bank 1 sensor 5, OBD code P2480 gets triggered.

What causes this problem with the Exhaust Gas Temperature Sensor Circuit/Open Bank 1 Sensor 5?

• The connectors or terminals might be sometimes loose or corroded
• Faulty wires or missing insulation might cause a short directly to ground
• Unusable sensor
• There might be a cat back exhaust system without EGT provisions installed
• Failure in the computer

1. Engine Control Module - There can be some engine performance issues due to faulty engine control module. If the ECM fails or has any problems it can lead to performance issues with the vehicle like misfires, hesitation, loss of power, and sometimes even decreased fuel economy.
2. Exhaust Gas Recirculation Valve - Did you just see check engine light flashing on your dashboard? If the computer would detect some fault with the automobile’s EGR valve circuit, then it would set up the check engine light so that the driver is notified about the fault. Don’t waste time and get them replaced or else this fault code can turn up.
3. Diesel Exhaust Fluid Pump - The diesel exhaust fluid pump needs to work properly if the transmission system has to perform. If it is not functioning, the transmission may slip and cause harsh shifts too. Thus replace faulty pump now and buy a new one from us!
4. Powertrain Control Module - PCM stands for powertrain control module. It is a car part, a control unit which is utilized on motor vehicles. It is generally a combined control unit, consisting of the engine control unit (ECU) and the transmission control unit (TCU).
5. Electronic Control Unit - If your automobile's check engine light remains on constantly, and never goes off, there's a good chance that your vehicle has a damaged electronic control unit. There are a lot of reasons why a car's check engine light will remain on. The most common reason is a defective ECU.
6. Diagnostic Tools - It is always advisable to use correct tools and equipment while resolving any OBD code issue as even small mistakes can lead to wrong diagnosis. Thus, always take help from a professional who has the knowledge and experience to such tools in efficient manner. Buy new quality diagnostic tools from us today!
7. Mass Air Flow Sensor – Replace faulty MAF sensor to avoid wrong reading of the intake air sending to the PCM, thus affecting the fuel delivery system. Buy new sensors from us now!
8. Fluid Pump - If the fluid pump is physically damaged, it can result in leakages, loss of pressure and harsh shifting. Thus, the fluid pump must be replaced, if found damaged. Buy new fluid pump from us now!
9. Engine Wiring Harness - The broken wires in the wiring harness might lead to some serious engine problems. So make sure that you replace your faulty engine wiring harness to avoid such situation.
10. Oxygen Sensor - Inspect for faulty O2 sensor that can affect the engine combustion process and the exhaust emissions. Thus, it is important to understand its importance and replace faulty oxygen sensor now!
11. Engine Coolant Temperature Sensor - The engine coolant temperature sensor is also known as the coolant temperature switch. It is an engine management system sensor which is utilized to monitor the temperature of the engine’s coolant. If there are any faults in the ECT sensor, then it would lead to engine performance issues. Purchase high grade engine coolant temperature sensor from us online.
12. Exhaust Gas Temperature Sensor – If the temperature sensor is not working properly, the ECU will not be able to predict the exhaust gas temperatures that can cause increase in vehicle emissions. Thus, replace faulty EGT sensor now!

Willing to know some common symptoms of OBD Code P2480? Your wish is our demand. Have a look at them below:

Common Symptoms

• Check engine light might come into signal
• A code for a failure in the EGT sensor circuit would be set in the engine control module
• Car engine might start running too rich or lean
• Leakage of exhaust before the sensor

We have listed out some ways which would help you to correct the occurrence of OBD Code P2480. They are mentioned here as follows:

• You must remove and clean the excessive soot and ash off of the EGT sensor
• Carefully adjust the faults in the EGT sensor
• Recondition the non-functioning wiring
• It is necessary to perform proper service of the exhaust leak in the pipe connection above the sensor
• Adjust the flawed electronic control unit

Here are some steps which you should follow in order to diagnose this P2480 fault code:

• The mechanic or the technician will use a diagnostic scanner or code reader like DVOM to visually scan for the error codes in the vehicle.
• After performing a careful inspection, every of the stored codes and freeze frame data are retrieved as it can help down the way for further diagnosis process.
• He should scan as well as document the codes in the engine control module and then the freeze frame data should be looked upon for some failures.
• Most often he has to inspect the EGT sensor and wiring itself to see if they are faulty or damaged.
• Examine the exhaust temperature of the EGT sensor 5 for bank 1 and then it should be compared to the EGT sensor 4 for bank 1.
• After that the sensor should be replaced if its reading are not as per the specifications set by the manufacturer.
• Every time a repair work is carried out, make sure that the mechanic test drives the vehicle after every repair so that the diagnosis is successful. This can eventually help him to know as to where the error occurred.

Common Mistakes When Diagnosing The P2480 Code

• Many a times the mechanic might not remove the EGT sensor and forget to inspect for excessive soot or ash on the sensor.
• Make sure that the EGT sensor is cleaned properly and it should be retested first before replacing it directly.
