P246A - OBD Trouble Code

<<See All OBD Codes

Error code P246A flashing? Can’t comprehend? Don’t know where to start from? Well, Parts Avatar has got you covered! Here’s all you need to know about the error code P246A. For appropriate circuit continuity and out of range high values, the powertrain control module (PCM) constantly regulates the exhaust gas temperature sensor (EGTS). One can find the exhaust gas temperature sensor located in front of the diesel oxidation catalyst (DOC) and/or in front of the diesel particulate filter (DPF). In order to control engine conditions to effectively reduce emissions, the EGTS installed detects exhaust gas temperature and alters it to a voltage and feeds back to the powertrain control module (PCM). The OBD-II code is stored by the PCM when the exhaust gas temperature sensor fails to fall within the factory specifications.

It should be noted that in order to convert the leftover exhaust particles to harmless gases, the diesel exhaust fluid (DEF) is used. For burning off these gases constantly, an increased temperature in the exhaust system is required. For achieving that, one should inject DEF fluid into the exhaust stream. This helps in bringing the temperature of diesel particulate filter (DPF) upto the point. Then the system is able to convert the harmful NOx to nitrogen, carbon dioxide and water. Further, to reduce the NOx present in the exhaust stream, reductant catalyst (SRC) is added. The exhaust temperature performs the function of informing the engine control module (ECM) about the temperature of the exhaust gas going in and out of the selective catalytic reduction (SCR). When an implausible signal coming from the EGT sensor, is detected by the powertrain control module, the code P246A is set.

What causes this problem with the Exhaust Gas Temperature Sensor Circuit Intermittent/Erratic Bank 2 Sensor 3?

• A possible defect in the exhaust gas temperature sensor (EGTS) bank 2 sensor 3
• The harness in the exhaust gas temperature sensor bank 2 sensor 3 is loose or short circuited
• A weak electrical connection in the exhaust gas temperature sensor bank 2 sensor 3 circuit
• Exhaust leakages
• Excessive buildup of particulate matter on the sensor

1. Powertrain Control Module - This essential unit if malfunctioning can cause irregular engine performance and sluggish engine start. We recommend you to change it as soon as possible in order to overcome these complications caused by the error code P246A.
2. Diesel Particulate Filter - Commonly, a dirty or jammed diesel particulate filter not only triggers the error code P246A but also problems like a deactivation of the start/stop button. Now get your error code P246A fixed right here with us. What are you waiting for? Get your filter changed now.
3. Turbocharger - Alarmed? Don’t know the reason behind the recurring error code P246A? Poor acceleration? Bad fuel economy? Well, fix your error code P246A now with a new turbocharger immediately.
4. Catalytic Converter - Facing the problems caused by the error code P246A? An inferior quality catalytic converter can always be hazardous for the system also it is one of the primal causes behind the occurring of the error code P224A. In addition to the code it also causes problems with the engine performance. Tune into Parts Avatar for supreme quality catalytic converters at economical prices.
5. Diesel Exhaust Fluid Pump - Stressed? Can’t figure out the reason behind the error code P246A and all these problems including an overall fall in the engine performance. All of this is likely caused due to a bad DEF pump. Tune into Parts Avatar to get your DEF pump changed now.
6. Exhaust Gas Temperature Sensor - Well, a defective exhaust gas temperature sensor can end up being the chief host inviting the error code P246A. In addition to the code, it also leads to problems with the overall functioning of the engine. So replacing one can be one of the wisest decisions to avoid a problematic system.
7. Exhaust System Parts - See the error code P246A popping again and again? Depreciating engine performance? A fall in the engine performance? Yes, all this is caused due to faulty exhaust system parts. Log into Parts Avatar, your one stop destination for your new exhaust system parts offered at budget friendly prices.

If you are facing OBD error code P246A, then there are significant common symptoms that can be felt or observed. We have worked out a list here to help you out in understanding this problem better.

Common Symptoms

• The engine light illuminated (or service engine soon warning light)

We have listed out some ways which would help you to correct the occurrence of OBD Code P246A. They are mentioned here as follows:

• Repair or replace your faulty exhaust gas temperature sensor (EGTS) bank 2 sensor 3
• Make sure you fix the weak electrical connection running in the exhaust gas temperature sensor bank 2 sensor 3 circuit
• All the harness in the exhaust gas temperature sensor bank 2 sensor 3 that are open or shorted should be repaired or replaced
• Fix all the exhaust leakages in the system
• A thorough cleansing should be performed of all the excessive buildup of particulate matter on the sensor

There is no need to get strained if your OBD code is still flashing up as we are here at your service. Have a look at our superior variety of PCM, diesel particulate filter, turbocharger, catalytic converter, diesel exhaust fluid, exhaust gas temperature sensor, exhaust system and many more. Now all your problems would vanish within no time.

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

To start with, a standard OBD-II trouble code scanner should be used to diagnose this trouble code P246A. The scanner will be used to check and view the freeze frame data and assess the code by a certified technician. The technician should also check for additional trouble codes stored. After the repairs have been performed, the codes should be retested and the vehicle should be restarted to see if the code pertains. If the code disappears it could likely be due to a faulty diagnose or may represent an intermittent issue.

Common Mistakes When Diagnosing The P246A Code

Here we have listed a few common mistakes that should be avoided while diagnosing the error code P246A:

• A fault in the exhaust gas temperature (EGT) sensor
• A defective powertrain control module (PCM)
• Wiring issues in the system
