Engine may hesitate during acceleration.Check engine or warning light may illuminate.Damaged or defective throttle position sensor.Damaged or defective mass airflow (MAF) sensor.
Damaged or defective BARO pressure sensor. DELPHI DIAGNOSTIC AUSTIN MAP CODE
Several problems may cause a P1109 code including: The ECM will then use the data to help calculate the best fuel delivery strategy for the most efficient engine operation.
P2230: Barometric Pressure Circuit Intermittentįor most automakers, a code P1109 will be stored when the wrong manifold air pressure (MAP) sensor voltage reading is detected for a preset amount of time, typically four seconds.Ī vehicle’s MAP and BARO sensor work to provide the ECM with information related to the amount or degree of air pressure, or vacuum, that is in the intake manifold at a given point in time. P2229: Barometric Pressure Circuit High. P2227: Barometric Pressure Circuit Range/Performance. P2074: Manifold Absolute Pressure/Mass Air Flow - Throttle Position Correlation at Higher Load. P2073: Manifold Absolute Pressure/Mass Air Flow - Throttle Position Correlation at Idle. P0316: Engine Misfire Detected on Startup (First 1000 Revolutions). P0109: Manifold Absolute Pressure/Barometric Pressure Circuit Intermittent. P0108: Manifold Absolute Pressure/Barometric Pressure Circuit High Input. P0107: Manifold Absolute Pressure/Barometric Pressure Circuit Low Input. P0106: Manifold Absolute Pressure/Barometric Pressure Circuit Range/Performance Problem. P0105: Manifold Absolute Pressure/Barometric Pressure Circuit. P0068: MAP/MAF – Throttle Position Correlation. Automakers with a P1109 trouble code include, but are not limited to Audi, Citroen/Peugeot, Daewoo, Fiat, Ford, General Motors, Lincoln, Mercury, Mini, Oldsmobile, Volkswagen, and Volvo. 
It means that the engine control module (ECM) has detected a signal voltage from the barometric (BARO) pressure sensor that is out of the predetermined range.īecause this is a manufacturer-specific code, each automaker may have a slightly different definition, steps for diagnosis, and repair information. The P1109 code is a manufacturer-specific fault code.
