What is the meaning of OBD-II code P0108, and what are the possible causes and solutions for this code to be generated?

The P0108 is a code for high voltage input in the MAP electrical circuit sensor, which affects the engine's performance by not allowing the ECU to receive proper input from the MAF and TPS. There are several possible causes for a P0108 code, such as: -High sensor range voltage input (above 5 volts) for the ECU -Bad MAP sensor -Bad wiring or connector, or located too close to high voltage components.Poor electrical ground -Sensor operating out of range due to age or damage -MAP sensors must work within .5 to 5 volts to send correct signals to the ECU -Engine in poor condition, missing, poor fuel pressure or internal issues (burned valve) can prevent the MAP sensor from getting a correct output -Rare: Bad ECU To diagnose a P0108 issue, a mechanic will use an OBD-II scanner and check if the fault code reappears after resetting it and road-testing the vehicle. If the code persists, they will perform a voltage test to determine if the MAP sensor needs replacement. The resolution to the P0108 code requires verifying the code with a scanner, resetting the fault codes, and performing a road test with live data streaming. If the code persists, check the MAP sensor voltage, electrical connector, and wiring, and determine if the MAP sensor or ECU is defective. Vehicles over 100k miles may experience sensor problems during start-up or drive train stress, but they can often be fixed by resetting the OBD-II system with a scanner. Before making repairs, it's important to verify and reset the fault.
