P050E OBD Error Code: Problem & Solutions

<<See All OBD Codes

If there is OBD error code P050E, then you have to know what OBD P050E code is. Its symptoms, causes and diagnostic methods. The PCM must have a critical maintaining temperature to minimize the emission and maintain the fuel economy. Once the engine starts, it has to reach this temperature within 15 minutes. During cold weather, the temperature has to rise 70+degrees. If it does not reach, it will be impossible for the PCM to control fuel economy and reduce emission and it will set the code P050E.

In cold climates, this code is common. The PCM monitors the exhaust temperature to make sure that the right action is taken to make these changes in temperature. Diesel exhaust fluid (DEF) injection systems is responsible for introducing the DEF into the catalytic converter and other parts of the exhaust system. The DEF mixture will increase the exhaust temperature that is needed to burn the harmful hydrocarbons and nitrogen dioxide particles caught within the exhaust system. PCM controls the injection system. During cold start, the exhaust temperature must be at the ambient temperature. If the exhaust temperature is lower than the ambient temperature the P050E code will be set and the MIL will be too bright.

What causes this problem with Cold Start Engine Exhaust Temperature?

• Faulty exhaust temperature sensor
• The wires of the exhaust temperature sensor are burnt or faulty
• Moisture inside the exhaust is frozen
• Error in the PCM or PCM programming

1. Exhaust Temperature Sensor - Are there any damages or leaks in your sensor? Why wait. Replace them immediately.
2. Exhaust Temperature Sensor Wiring * The wires which connects the sensor and other components has to be damage free. Replace them if you find any damages.
3. Fuel Injection Systems - Check for the DEF injection system if it is disabled. If it is disabled, enable them.
4. Powertrain Control Module - A faulty / broken / damaged powertrain control module can cause trouble to your system. Replace them with right components from Parts Avatar.

Interested in knowing the symptoms of the OBD code P050E? If yes, then you have arrived at the right place. We at Parts Avatar have listed out few common symptoms associated with Cold Start Engine Exhaust Temperature.

Common Symptoms

• Reduced Engine Performance
• Reduced Fuel Efficiency
• Extreme Black Smoke from the Exhaust
• Associated DEF Codes

Have a look at some ways with which you can correct the P050E code:

• After visually inspecting the exhaust temperature sensor wires and connectors (with a focus on wiring that is routed near high-temperature areas), now connect the scanner to the diagnostic port of the vehicle and restore all stored codes and relevant data. This code may be helpful for diagnostic process and so note them down in a safe place. Now, clear the codes and test-drive the vehicle again (at cold start) to see if the code is reset. Test-drive will also remove any moisture which was previously trapped in the exhaust system.

There is no need to get strained if your OBD Code is still flashing up as we are here at your service.

Now all your problems would vanish within no time.

Look at a few ways as to how to diagnose the P050E code

• Fix the DVOM to the ohms setting.
• Separate the sensor from the wiring joints.
• To test the sensor, use the specifications and testing procedures as mentioned by the manufacturer.
• You have to observe the exhaust temperature by using the scanner data stream display
• Compare both the exhaust temperature displayed on scanner and the actual temperature with the help of IR thermometer.
• If both the readings vary by maximum allowable threshold, there can be a faulty exhaust temperature sensor. If both are within specification, there can be fault PCM or programming error.

Common mistakes when diagnosing the OBD P050E code

• Faulty Ambient air temperature sensor failure
• Faulty Exhaust temperature sensor failure
