DTC P0106: Barometric Pressure Out Of Range: Description

NOTE: Vehicles equipped with a 2.7L engine are equipped with a Manifold Absolute Pressure (MAP) sensor. Vehicles equipped with a 3.2L and 3.5L engine are equipped with an Intake Air Temperature/Manifold Absolute Pressure (IAT/MAP) sensor. For this test, IAT/MAP will be identified as MAP sensor.

Manifold Absolute Pressure (MAP) sensor voltage is monitored with ignition on and engine speed less than 250 RPM. DTC will set in Powertrain Control Module (PCM) memory when PCM senses MAP sensor voltage is less than 2.196 volts but more than .0392 volt for 300 milliseconds. Possible causes are: 5-volt supply circuit open or shorted to ground or voltage, defective MAP sensor, signal circuit open or shorted to ground, or defective PCM.
