Error Code P2477: What It Means & What To Do?

P2477 OBD error code relates to your vehicle’s exhaust gas temperature sensor. Your vehicle’s Powertrain Control Module (PCM) will set this error code when it detects that EGT sensor for the Bank 2 and Sensor 4 is not within the required range or factory specifications. If you want to correct this issue with your vehicle, you will need to understand few of its common causes first, in order to do that take a look at the section below.

What causes this problem with the Exhaust Gas Temperature Sensor Circuit Intermittent/Erratic Bank 2 Sensor 4?

• Malfunctioning exhaust gas temperature sensor bank 2 sensor 4
• Open or shorted EGT sensor bank 2 sensor 4 harness
• Weak electrical connection for the EGT sensor bank 2 sensor 4
• Leaking exhaust system
• Excessive particulate matter buildup on the EGT sensor bank 2 sensor 4

1. Powertrain Control Module - Error code P2477 flashing? Yes? Then you must check for PCM error which might be due to circuit faults that might require complete replacement and reprogramming. Replace it now!
2. Exhaust Gas Temperature Sensor - Well, a damaged Exhaust Gas Temperature sensor can damage other internal components and cause the failure of the system. Alter the defective EGT sensor as soon as possible.
3. Diesel Particulate Filter - OBD error code P2477 flashing? Chances are that there could be a problem with your vehicle’s DEF, but don’t let that hold you back, fix your def filters and related parts now. You can find with us top notch def parts at the most budget friendly prices.
4. Engine Control Module - You can’t afford to go a long way with your defective engine control module as it will lead no start condition or engine stalling. So, it’s definitely a good idea to replace the damaged ones today. Buy best priced engine control modules with us for all make and models.
5. Engine Control Unit - Having poor engine performance or unexplained drops in fuel economy is associated to defective ECU issues, so what are you waiting for? Replace the bad ones today.
6. Catalytic Converter - Chances of catalytic converter being damaged is high, as they are continually exposed to heat. If you need new cat converter to get rid of this error code P2477 then you can find one with us at PartsAvatar. 

Our main motive is to achieve customer satisfaction and that’s why we will help you to diagnose P2477 code by mentioning some major symptoms below:

Common Symptoms

• Fall in engine performance

Have a look at some ways with which you can correct the P2477 code:

• Begin with fixing or replacing the damaged exhaust gas temperature sensor
• Undergo blown out fuses replacement
• Carbon buildup from the connector must be removed
• Fix the exhaust leak
• Also make sure that connectors must be cleaned for any corrosion
• Next, Faulty wirings must be repaired or replaced
• Repair the faulty car’s ECU

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

• To start with your diagnosis of OBD error code P2477, you will need to look for the technical service bulletins, also known as the TSB’s specific to your vehicle make model and year. Believe us this will save you a lot of time and will guide you in the right direction.
• Next step in your diagnosis step is to find and locate all the parts within the exhaust gas temperature circuit and undergo a complete visual inspection to make sure there are no defects such as scraping, rubbing, bare wires or burn spots.
• Now, inspect all the related connectors for any corrosion or defective pins. For those who don’t know this already, the exhaust gas temperature sensor is generally a 2-wire sensor located in your vehicle’s exhaust down pipe.
• Remove the exhaust gas temperature and check for any carbon buildup. Also, check for any fuel injector or exhaust leakage.

Common Mistakes When Diagnosing The P2477 Code

If you are going to diagnose your vehicle for OBD error code P2477, then make sure that you avoid the following errors

• Problematic exhaust gas temperature (EGT) sensor
• Problematic powertrain control module (PCM)
• Problematic wiring
