Code P1109 2010 Honda Accord Description
The P1109 code for a 2010 Honda Accord indicates that there is an issue with the BARO (Barometric Pressure) sensor circuit being out of range high. The BARO sensor is responsible for measuring the atmospheric pressure outside the vehicle, which is crucial for the engine's air-fuel ratio calculations. When the BARO sensor circuit is out of range high, it means that the sensor is detecting a barometric pressure that is higher than normal, which can lead to incorrect fuel mixture adjustments by the engine control module (ECM).
