Error Code P2473: What It Means & What To Do?

<<See All OBD Codes

If you are experiencing excessive exhaust emissions and fall in the engine performance and power, then the chances are that there is some problem with your vehicle’s exhaust gas temperature sensor circuit. It might be low or high or out of factory specifications. You must be wondering now what does this code indicates and how does this affects your engine performance. To get the answers to all your questions you will need to go through the following sections.

OBD error code P2473 will be set by your vehicle’s powertrain control module when it detects that there is some issues with functioning of the vehicle’s EGT sensor bank 2 sensor 4. Vehicle’s powertrain control module is responsible for monitoring the EGT sensors. The EGT sensor bank 2 sensor 4 contains the number 1 cylinder. OBD error code flashes when PCM detects out of factory specifications signals from the exhaust gas temperature sensor bank 2 sensor 4.

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

• Exhaust Gas Temperature bank 2 sensor 4 being faulty
• Exhaust Gas Temperature bank 2 sensor 4 wires or harnesses being open or shorted
• Exhaust Gas Temperature bank 2 sensor 4 poor electrical connection
• A possible leaking exhaust
• Sensor developing excessive particulate matter buildup

1. Catalytic Converter - Chances of catalytic converter being damaged is quite high, as they are continually exposed to engine heat. If you need new cat converter to get rid of this error code P2473 then you can find one with us at PartsAvatar.
2. 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.
3. Exhaust Gas Temperature Sensor - EGT sensor damaged? Do you know what it means? Well, this means that you won’t be able to get a warning for potential engine damage. Don’t let that happen and replace the faulty ones now.
4. Diesel Particulate Filter - If the DPF parts are not functioning properly, they can cause increased emissions in the exhaust system and reduce the longevity of the filtration elements in the exhaust system. Thus, replace faulty ones today.
5. Exhaust System Parts - We have in stock high end exhaust system parts for all makes and models. So, don’t waste time and get your hand on our best range of auto parts today.

If you want to easily diagnose this fault code, then all you have to do is to follow the steps which are mentioned below:

If you wish to diagnose this OBD error code P2473, then you will need to look for the technical service bulletins, also known as the TSB’s specific to your vehicle make model and year. This will save you a lot of time and will guide you in the right direction. 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. After this you will need to 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. Last but not the least 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 P2473 Code

If you are going to diagnose your vehicle for OBD error code P2473, then make sure that you avoid the following errors

• Bad EGT sensor
• Defective powertrain control module (PCM)
• Damaged wiring
