P0106: MAP/Barometric Pressure Circuit Range/Performance
3 vehicles · 2 makes · $100-$800 repair
Most Reported On
P0106 is an OBD-II diagnostic trouble code meaning “MAP/Barometric Pressure Circuit Range/Performance.” P0106 means the manifold absolute pressure (MAP) or barometric pressure sensor signal is out of the expected range or not matching engine operating conditions (range/performance). The MAP sensor measures intake manifold pressure/vacuum, which the computer uses to gauge engine load and calculate the correct fuel and ignition timing. When the reading is implausible — too steady, not tracking throttle changes, or inconsistent with other sensors — the computer flags this code. Symptoms often include rough idle, hesitation, poor fuel economy, or a lack of power, and the cause may be the sensor, a vacuum leak, or wiring. This code is most commonly reported on 2012-2020 Chevrolet Sonic, 2011-2016 Chevrolet Cruze, and 2013-2021 Buick Encore, with repair costs ranging from $100 to $800.
