DTC P0106 Manifold Absolute Pressure / Barometric Pressure Circuit Range / Performance Problem
The manifold absolute pressure sensor detects the intake manifold pressure by using the built-in sensor unit. The ECM determines the basic injection duration and injection advance timing based on the voltage output by the manifold absolute pressure sensor.
The manifold absolute pressure sensor monitors the absolute pressure inside the intake manifold (default is 0 kPa (0 mmHg, 0 in.Hg)). As a result the ECM controls the air-fuel ratio at the proper level under any driving conditions, and is not influenced by fluctuations in the atmospheric pressure due to factors such as high altitude, etc.

|DTC No.||DTC Detection Condition||Trouble Area|
|P0106||Voltage output of the manifold absolute pressure sensor is out of the standard range
(2 trip detection logic)
|Manifold absolute pressure sensor|
If DTCs P0105, P0107, and P0108 are output simultaneously, the manifold absolute pressure sensor circuit may have an open or short. Perform troubleshooting for these DTCs first.
|1.CHECK OTHER DTC OUTPUT (IN ADDITION TO DTC P0106)|
Connect the intelligent tester to the DLC3.
Turn the ignition switch on (IG) and turn the tester ON.
Enter the following menus: Powertrain / Engine and ECT / DTC.
Display (DTC Output) Proceed to P0106 A P0106 and other DTCs BHINT:
If codes other than P0106 are output, perform troubleshooting for those DTCs first.
