The diagnostic trouble code (DTC) P0106 refers to a problem with the Barometric Pressure Sensor Circuit. The code indicates that the sensor's output signal is not within the expected or acceptable range as defined by the vehicle's manufacturer. The Barometric Pressure Sensor is responsible for measuring the atmospheric pressure and providing this information to the engine control module (ECM) or powertrain control module (PCM). The ECM/PCM uses this data to adjust the air-fuel mixture and ignition timing to optimize engine performance and efficiency. When the P0106 code is triggered, it typically means one of the following issues is occurring: 1. Faulty Barometric Pressure Sensor: The sensor itself may be defective, providing inaccurate readings or no signal at all. 2. Wiring or Connector Issues: There could be a problem with the wiring leading to the sensor or the connector that connects the sensor to the ECM/PCM. This could be due to damaged wires, loose connections...
