|P0106||Manifold Absolute Pressure / Barometric Pressure Circuit Range / Performance Problem|
By a built-in sensor unit, the manifold absolute pressure sensor detects the intake manifold pressure as a voltage. The ECM then determines the basic injection duration and basic ignition advance angle based on this voltage.
Since the manifold absolute pressure sensor does not use the atmospheric pressure as a criterion, but senses the absolute pressure inside the intake manifold (the pressure in proportion to the preset absolute vacuum 0), it is not influenced by fluctuations in the atmospheric pressure due to high altitude and other factors. This permits it to control the air fuel ratio at the proper level under all conditions.
|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 be open or shorted. Perform troubleshooting for those DTCs first.
CHECK OTHER DTC OUTPUT
Replace the normal DLC3 cable (12 V specification) for the intelligent tester with the 24 V DLC3 cable.
Be sure to use the 24 V DLC3 cable when connecting the intelligent tester to the DLC3. Using the normal DLC3 cable (12 V specification) will cause damage to the tester.
Connect the intelligent tester to the DLC3.
Turn the ignition switch to ON.
Turn the tester on.
Enter the following menus: Powertrain / Engine and ECT / DTC.
Read the DTCs.
