RAM Code P262D is an error code that can be triggered by a malfunctioning Mass Air Flow Sensor (MAF) or a shorted 12-volt Supply circuit. A flashing ETC Lamp and limp mode often accompany this error code. The Powertrain Control Module (PCM) will turn off the MIL after the diagnostic runs and passes in four consecutive drive cycles. A thorough understanding of the cause and solution of RAM Code P262D is essential for proper diagnosis and repair.

Causes and Solutions of RAM Code P262D
| Cause | Solution |
|---|---|
| MASS AIR FLOW (MAF) SENSOR | Replace the MAF Sensor |
| 12-VOLT SUPPLY CIRCUIT SHORTED TO GROUND | Check for breaks and repair the 12V Supply Circuit |
| POWERTRAIN CONTROL MODULE (PCM) | Replace or reset the PCM |
| Failed MIL Diagnostics | Check and repair faulty wiring or components and then run the diagnostic again. |
MASS AIR FLOW (MAF) SENSOR
RAM Code P262D is often caused by a malfunctioning Mass Air Flow (MAF) Sensor. This sensor monitors the air entering the engine and provides the engine control module with the data it needs to adjust fuel trim. If the engine control module does not receive the proper air/fuel ratio data, it will set RAM Code P262D. The solution is to replace the MAF Sensor.
12-VOLT SUPPLY CIRCUIT SHORTED TO GROUND
Another common cause of RAM Code P262D is a shorted 12-volt Supply circuit. This 12-volt Supply circuit powers the MAF Sensor and any other connected components. When this circuit is shorted to ground, the MAF Sensor will not receive the necessary strength, and the engine control module will set RAM Code P262D. To fix this issue, you must check for breaks in the 12-volt Supply circuit and repair any cracks that are found.
POWERTRAIN CONTROL MODULE (PCM)
Sometimes, the Powertrain Control Module (PCM) may cause RAM Code P262D. In this situation, the PCM must be replaced or reset. A qualified technician should do this as it requires special tools and knowledge.
Failed MIL Diagnostics
A failed MIL Diagnostics can also be the cause of RAM Code P262D. If the diagnostic fails, it is likely due to faulty wiring or components. In this case, you must check the wiring and components and repair any issues. Once the repairs have been made, you must run the diagnostic again to see if RAM Code P262D has been cleared.
Conclusion
RAM Code P262D is an error code caused by a malfunctioning Mass Air Flow Sensor (MAF) or a shorted 12-volt Supply circuit. The solution to the code depends on the cause of the issue. A thorough understanding of the cause and solution of RAM Code P262D is essential for proper diagnosis and repair. If all the causes and solutions listed above are followed, the code should be cleared, and the vehicle should run normally.
