P246E - OBD Trouble Code

<<See All OBD Codes

Love hitting the roads? But hate these halts? It could all be due to an OBD error in your system. Here’s how you can diagnose and treat the OBD error code P246E. This generic OBD-II code powertrain control module (PCM) failure is also known as an exhaust gas temperature sensor circuit. It can be seen that the diesel exhaust fluid (DEF) is employed to help while converting the remaining exhaust particles to harmless gases. A high temperature in the exhaust system is required in order to burn off those particles. The temperature is brought to level by the diesel particulate filter when the DEF fluid is injected into the exhaust stream. Then the system performs the task of converting the harmful NOx to nitrogen, carbon dioxide and water. Also, reductant catalyst (SRC) is added to decrease the NOx content in the exhaust stream. The temperature going in and out of the selective catalytic reduction is notified to the engine control module (ECM) by the exhaust gas temperature sensor (EGT). The code P246E is stored, when the PCM detects an impractical signal

from the EGT sensor.

For suitable circuit continuity and out of range high values, the powertrain control module (PCM) constantly regulates the exhaust gas temperature sensor (EGTS). You can find the EGTS situated front of the diesel oxidation catalyst (DOC) and/or in front of the diesel particulate filter (DPF). The EGTS performs the function of detecting the exhaust gas temperature and then converting it into a voltage. This is further sent to the powertrain control module with the voltage signal in order to monitor the control engine conditions to effectively reduce emissions. The code P246E is set by the PCM, when the exhaust gas temperature sensor fails to fall within the factory specifications.

What causes this problem with the Exhaust Gas Temperature Sensor Circuit Bank 1 Sensor 4?

• A damaged exhaust gas temperature sensor (EGTS) bank 1 sensor 4
• Burnt or disconnected harness in the exhaust gas temperature sensor bank 1 sensor 4
• A deficient electrical connection in the exhaust gas temperature sensor bank 1 sensor 4
• Exhaust leakages in the system
• Particulate matter accumulated on the sensor

1. Powertrain Control Module - A lot of issue can come up due to a defective PCM, including rough idle, poor engine performance, hesitation and stalling. A damaged one should be changed or repaired immediately if you want to get rid of the error code P246E.
2. Exhaust Gas Temperature sensor - Engine overheating? Check engine light flashing on? Fall in the fuel economy? Yes, all this is likely to follow a defective exhaust gas temperature sensor. Tune into Parts Avatar for your new exhaust gas temperature sensor offered at just the right prices.
3. Exhaust System Parts - Can’t figure out the reason behind the error code P246E? Well, it is often triggered due defective exhaust system parts. Apart from this problems with the fuel efficiency, loss of power and no acceleration can be observed too. Mend or restore your exhaust system parts now! Tune into Parts Avatar for you brand new exhaust system parts available at budget friendly prices.
4. Diesel Oxidation Catalyst - The diesel oxidation catalyst performs the function of breaking down the pollutants in the exhaust stream. Mend or restore it now in order to get rid of all these problems caused by the error code P246E.
5. Diesel Particulate Filter - A blocked diesel particulate filter can end up being the chief host inviting the error code P246E. So replacing one can be one of the wisest decisions to avoid a problematic system.
6. Automatic Transmission Cooler - Leaking fluid? Grinding gears? Dashboard lights blinking? Well, the reason behind it can be a defective automatic transmission cooler. Repair or replace it immediately if malfunctioning

It is essential to know the symptoms of an issue as only then you would be able to solve the problem. So that’s why we have listed out some major symptoms of OBD code P246E here:

Common Symptoms

• An illuminated check engine light (or service engine soon warning light) is observed

Here are some ways with the help of which you will be able to correct the OBD code P246E:

• Replacements of repairs should be performed of a damaged exhaust gas temperature sensor (EGTS) bank 1 sensor 4
• All the burnt or open harness in the exhaust gas temperature sensor bank 1 sensor 4
• Make sure you fix a bad electrical connection running in the exhaust gas temperature sensor bank 1 sensor 4
• All the exhaust leakages within the system should be mended
• A thorough cleansing should be performed of all the particulate matter accumulated on the sensor to avoid any problems

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

With the pressure put by the foot down on the brakes, the car comes down slowly to a stop. The power applied on the brake pedal is aided by the hydraulic pressure. The foot’s force tends to engage a piston and caliper with brake pads attached (bonded abrasive and heat resistance metal or ceramic) in order to put pressure on the rotor. The code is valid to the vehicles that have electronically controlled automatic transmissions. For activating the hydraulic circuits to actuate clutches or bands that change gears inside the automatic transmission, the 3-4 shift solenoid is used. If the transmission functions well, and the code fails to return after a check has been performed (after all the repairs and replacements), the it was caused due to a transmission slippage (because of a low fluid level/pressure condition). In case, if it does, the transmission slips or suffers from delayed engagement should be blamed. Also, the pump pressure should be checked using a manual pressure gauge. Utilize the digital volt/ohmmeter to check for continuity (disconnect all related control modules from the circuit before checking circuit resistance or controller damage may occur) and resistance in all circuits if either the reference voltage or ground circuits are disconnected. Most of the vehicles use an electronically controlled valve in the automatic transmission cooler lines to control the flow of fluid to the cooler itself. If in case the code fails to return, an intermittent condition should be suspected.

Common Mistakes When Diagnosing the P246E Code

Here we have listed a few common mistakes that should be avoided while diagnosing the error code P246E:

• A failed exhaust gas temperature (EGT) sensor
• Damaged powertrain control module (PCM)
• Wiring problems present in the system
