DTC P2228: Barometric Pressure Circuit Low Input

M11310100270USA0000010000

TECHNICAL DESCRIPTION

｠

The barometric pressure sensor outputs a voltage
which corresponds to the barometric pressure.

｠

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.

To prevent damage to scan tool MB991958, always turn the
ignition switch to the "LOCK" (OFF) position before
connecting 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 24 P.
13Ab-8.

(4)

Check the diagnosis trouble code (DTC).

Q:Is DTC P02228 set?

YES:

Replace the ECM. When the ECM is replaced, register

the ID code. Refer to GROUP 42B, ID Code Registration
Judgment Table <Vehicles with KOS> P.42B-12or GROUP
42C, ID Code Registration Judgment Table <Vehicles with
WCM> P.42C-8.

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 P.00-15.
