Understanding P0106 in detail
P0106 indicates a sensor signal used for air measurement, temperature, pressure, or throttle correlation is outside the expected range. Air metering faults can come from dirty sensors, intake leaks, wiring damage, failed MAP/MAF/IAT sensors, throttle body problems, or low voltage. Inspect the intake tract and compare live sensor data before replacing parts.
