P1106 Barometric Pressure Sensor Range Performance Problem

• Code: P0105
  
  Description: Manifold Absolute Pressure/Barometric Pressure Circuit Malfunction
  
  Definition: This code indicates a problem with the MAP sensor or its circuit, which affects the barometric pressure readings.
• Code: P0106
  
  Description: Manifold Absolute Pressure/Barometric Pressure Circuit Range/Performance Problem
  
  Definition: This code is triggered when the MAP sensor signal does not match the expected engine load or RPM conditions.
• Code: P0107
  
  Description: Manifold Absolute Pressure/Barometric Pressure Circuit Low Input
  
  Definition: Indicates that the MAP sensor signal voltage is lower than expected, suggesting an issue such as a vacuum leak or faulty sensor.
• Code: P0108
  
  Description: Manifold Absolute Pressure/Barometric Pressure Circuit High Input
  
  Definition: This code suggests that the MAP sensor signal voltage is higher than expected, possibly due to a short circuit or defective sensor.

OBD2 Code: P1106

Description: Barometric Pressure Sensor Range/Performance Problem

Common Misdiagnosis: Replacing the barometric pressure sensor without checking for vacuum leaks or issues with the intake manifold.

 

Common Diagnostic Steps

OBD2 Code: P1106

Description: Barometric Pressure Sensor Range/Performance Problem

• Check for any additional codes that may indicate a related issue.
• Inspect the barometric pressure sensor and its wiring for damage or disconnections.
• Verify the sensor’s electrical connections are secure and free of corrosion.
• Use a multimeter to test the sensor’s voltage output against manufacturer specifications.
• Compare the barometric pressure reading with a known good source, such as a weather report or another vehicle’s sensor reading.
• If discrepancies are found, consider replacing the barometric pressure sensor.
• Clear the code and perform a test drive to see if it returns after repairs are made.
