MIL Illuminated: Understanding DTC P0107

What does it indicate when the MIL is illuminated on a late-model vehicle and DTC P0107 is obtained?

A. A failure in the vehicle's powertrain

B. A manufacturer-specific code

Answer:

Technician B is right because DTC P0107 is not manufacturer-specific.

Understanding DTC P0107 and the MIL Illumination

When the Malfunction Indicator Lamp (MIL) is illuminated on a late-model vehicle and the Diagnostic Trouble Code (DTC) P0107 is obtained, it does not indicate a failure in the vehicle's powertrain. Instead, it points to a specific issue with the Manifold Absolute Pressure (MAP) sensor.

DTCs, including P0107, are standardized across most vehicles and are not manufacturer-specific. They provide a consistent way to diagnose issues related to various components in a vehicle.

In the case of DTC P0107, it signifies a problem with the MAP sensor's circuit, such as a high voltage condition. This code can help technicians pinpoint and address issues related to the MAP sensor efficiently.

It's important to note that DTCs like P0107 are defined in On-Board Diagnostics (OBD-II) guidelines, ensuring that technicians have a clear understanding of the code and how to proceed with diagnosis and repairs.

Therefore, Technician B is correct in stating that DTC P0107 is not manufacturer-specific. It represents a common issue with the MAP sensor's circuit and does not necessarily point to a powertrain problem. Understanding these codes is essential for effective vehicle diagnostics and maintenance.
