P0106 on Chevrolet
MAP/Barometric Pressure Circuit Range/Performance
P0106 on Chevrolet vehicles indicates map/barometric pressure circuit range/performance. Au7o has documented this code across 1 Chevrolet model — most commonly on Sonic. 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. Typical repair costs on Chevrolet range from $150 to $500, depending on the specific model and root cause.
Common Causes of P0106
- •Faulty MAP sensor
- •Vacuum leak or disconnected/cracked vacuum line to the sensor
- •Clogged or restricted MAP sensor port
- •Wiring or connector problems in the sensor circuit
- •Intake manifold leak affecting pressure readings
- •Restricted air intake or exhaust affecting manifold pressure
- •Poor ground or reference voltage to the sensor
P0106 on Chevrolet by Model
Chevrolet Sonic(1 issue)
- 1.4L Turbo PCV Valve Cover Diaphragm Failure2012-2020
The 1.4L turbocharged Ecotec engine in the Sonic shares the notorious PCV system failure with the Chevrolet Cruze. The PCV regulator diaphragm integrated into the valve cover ruptures, causing massive vacuum leaks. Additionally, the intake manifold check valve (small red/orange valve) fails, compounding the issue. This affects virtually all 1.4T Sonics eventually, typically between 50,000-100,000 miles.

What does P0106 mean on Chevrolet?▼
P0106 stands for "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. On Chevrolet specifically, this code is documented across 1 model.
What causes P0106 on Chevrolet vehicles?▼
