POWER BRAKE UNIT VACUUM SENSOR INSPECTION [WITHOUT CYLINDER DEACTIVATION (SKYACTIV-G 2.0, SKYACTIV-G 2.5)]

id0140m1889400


Function Inspection

1.  Connect the M-MDS to the DLC-2.

2.  Switch the ignition ON (engine off).

3.  Display the PID BBP. (See OBD ON-BOARD SYSTEM READINESS TEST [PCM (WITHOUT CYLINDER DEACTIVATION (SKYACTIV-G 2.0, SKYACTIV-G 2.5))].) (See PCM INSPECTION [WITHOUT CYLINDER DEACTIVATION (SKYACTIV-G 2.0, SKYACTIV-G 2.5)].)

4.  Compare the voltage and power brake unit vacuum indications for the PID BBP with the standard in the table indicated below.

•  If they do not match the standard, replace the PCM. (See PCM REMOVAL/INSTALLATION [WITHOUT CYLINDER DEACTIVATION (SKYACTIV-G 2.0, SKYACTIV-G 2.5)].)
•  If they match the standard, perform the voltage inspection. (See Voltage Inspection.)

Voltage Inspection

1.  Connect the M-MDS to the DLC-2.

2.  Switch the ignition ON (engine off).

3.  Verify that the power brake unit vacuum sensor output voltage (PID: BBP) is within the specification. (See OBD ON-BOARD SYSTEM READINESS TEST [PCM (WITHOUT CYLINDER DEACTIVATION (SKYACTIV-G 2.0, SKYACTIV-G 2.5))].) (See PCM INSPECTION [WITHOUT CYLINDER DEACTIVATION (SKYACTIV-G 2.0, SKYACTIV-G 2.5)].)

•  If not within the specification, replace the power brake unit vacuum sensor. (See POWER BRAKE UNIT VACUUM SENSOR REMOVAL/INSTALLATION [L.H.D.].) (See POWER BRAKE UNIT VACUUM SENSOR REMOVAL/INSTALLATION [R.H.D.].)
