MULTIPORT FUEL INJECTION (MFI) DIAGNOSIS
TSB Revision
MULTIPORT FUEL INJECTION (MFI) <2.4L ENGINE>
13A-667
STEP 16. Using scan tool MB991958, read the diagnostic
trouble code (DTC).
CAUTION
To prevent damage to scan tool MB991958, always turn the
ignition switch to the "LOCK" (OFF) position before con-
necting or disconnecting scan tool MB991958.
(1) Connect scan tool MB991958 to the data link connector.
(2) Turn the ignition switch to the "ON" position.
(3) After the DTC has been deleted, read the DTC again.
(4) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is DTC P2138 set?
YES : Retry the troubleshooting.
NO : The inspection is complete.
DTC P2228: Barometric Pressure Circuit Low Input
.
TECHNICAL DESCRIPTION
• The barometric pressure sensor outputs a volt-
age which corresponds to the barometric pres-
sure.
• The ECM checks whether this voltage is within a
specified range.
.
DESCRIPTIONS OF MONITOR METHODS
Barometric pressure sensor output voltage is out of
reasonable barometric pressure range.
.
MONITOR EXECUTION
Continuous

DTC SET CONDITIONS
Logic Flow Chart
Check Conditions
• 2 seconds or more have passed since the engine
starting sequence was completed.
• Battery positive voltage is higher than 6 volts.
Judgement Criterion
• Barometric pressure sensor output signal has
continued to be 49 kPa (14.5 in.Hg) or lower
(approximately 15,000 ft above sea level) for 10
seconds.

MULTIPORT FUEL INJECTION (MFI) <2.4L ENGINE>
13A-669
STEP 1. Test the OBD-II drive cycle.
CAUTION
To prevent damage to scan tool MB991958, always turn the
ignition switch to the "LOCK" (OFF) position before con-
necting or disconnecting scan tool MB991958.
(1) Connect scan tool MB991958 to the data link connector.
(2) Turn the ignition switch to the "ON" position.
(3) Carry out the test drive with the drive cycle pattern. Refer to
DIagnostic Function
− OBD-II Drive Cycle − Pattern 23
(4) Check the diagnostic trouble code (DTC).
Q: Is DTC P2228 set?
YES : Replace the ECM. When the ECM is replaced,
register the ID code. Refer to GROUP 42B, Diagnosis
− ID Code Registration Judgment Table <Vehicles
or GROUP 42C, Diagnosis
− ID
Codes Registration Judgment Table <Vehicles with
WCM>
NO : It can be assumed that this malfunction is intermittent.
Refer to GROUP 00, How to Use
Troubleshooting/Inspection Service Points
− How to
Cope with Intermittent Malfunctions
