P0106 on Infiniti
MAP/Barometric Pressure Circuit Range/Performance
P0106 on Infiniti vehicles indicates map/barometric pressure circuit range/performance. Au7o has documented this code across 2 Infiniti models — most commonly on Q50, Q60. 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.
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 Infiniti by Model
Infiniti Q50(1 issue)
- VR30DDTT Internal Turbocharger Oil Leak (Emissions Warranty Extension to 10yr/120k)2016-2018
The turbocharger center bearing on the 3.0L twin-turbo VR30DDTT can wear prematurely and let engine oil leak internally past the bearing seals into the exhaust and intake tracts. Oil burning in the exhaust produces heavy white or blue smoke, fouls the catalyst, and trips the MIL. In severe cases the turbo loses boost control and the internal components come apart, which can send debris downstream. Infiniti acknowledged the defect with a turbocharger emission warranty extension covering 2016-2018 Q50 and 2017-2018 Q60, extending coverage on the turbocharger assembly to Full Useful Life — 10 years or 120,000 miles, whichever comes first — when the failure presents as white smoke or an oil leak with a MIL-on condition.
Infiniti Q60(1 issue)
- VR30DDTT Internal Turbocharger Oil Leak (Emissions Warranty Extension to 10yr/120k)2017-2018
The turbocharger center bearing on the 3.0L twin-turbo VR30DDTT wears prematurely and lets engine oil leak internally past the bearing seals into the exhaust and intake tracts. Burning oil produces heavy white or blue smoke, fouls the catalyst, and trips the MIL; in severe cases the turbo loses boost control and comes apart internally, sending debris downstream. Infiniti acknowledged the defect with a turbocharger emission warranty extension covering 2017-2018 Q60 alongside 2016-2018 Q50, extending coverage on the turbocharger assembly to Full Useful Life — 10 years or 120,000 miles, whichever comes first — where the failure presents as white smoke or an oil leak with a MIL-on condition.

What does P0106 mean on Infiniti?▼
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 Infiniti specifically, this code is documented across 2 models.
What causes P0106 on Infiniti vehicles?▼
Common causes on Infiniti: 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. Specific causes vary by model and year — see the per-model sections below.
How much does it cost to fix P0106 on a Infiniti?▼
Repair costs vary widely depending on the root cause and specific Infiniti model.
Which Infiniti models have P0106 documented?▼
Au7o has documented P0106 on 2 Infiniti models: Q50, Q60.
