P0107

Fix code P0107 Manifold Absolute Pressure/Barometric Pressure Circuit Low The Manifold Absolute Pressure sensor/Barometric Pressure Sensor (MAP/BARO)is a “speed density” method of determining the air fuel ratio. The sensor measures intake manifold vacuum, which varies depending on how wide open the throttle is. However, while the pistons are pulling a vacuum on the down-stroke, outside barometric pressure is also pushing air into the cylinder. So the sensor actually takes two readings—one before the engine starts (barometer pressure) and one after the engine starts. Once the engine is running, the computer … Read More

P0105 Manifold Absolute Pressure/Barometric Pressure Circuit Malfunction

Fix code P0105 The Manifold Absolute Pressure sensor/Barometric Pressure Sensor (MAP/BARO)is a “speed density” method of determining the air fuel ratio. The sensor measures intake manifold vacuum, which varies depending on how wide open the throttle is. However, while the pistons are pulling a vacuum on the down-stroke, outside barometric pressure is also pushing air into the cylinder. So the sensor actually takes two readings—one before the engine starts (barometer pressure) and one after the engine starts. Once the engine is running, the computer constantly monitors the changing voltage from … Read More
