(1)
Disconnect the manifold absolute pressure sensor connector
B-105 between the ECM connector B-10.
a
.
Measure the resistance between the manifold absolute
pressure sensor connector B-105 (terminal No. 3) and the
ECM connector B-10 (terminal No. 44).
b
.
Measure the resistance between the manifold absolute
pressure sensor connector B-105 (terminal No. 1) and the
ECM connector B-10 (terminal No. 45).
c
.
Measure the resistance between the manifold absolute
pressure sensor connector B-105 (terminal No. 2) and the
ECM connector B-10 (terminal No. 46).
⦆
Should be less than 2 ohms.
Q:Is the harness wire in good condition?
YES:
Go to step 4.
NO:
Repair it. Then go to Step 6.
STEP 4. Replace the manifold absolute pressure sensor.
(1)
Replace the manifold absolute pressure sensor.
(2)
Carry out a test drive with the drive cycle pattern. Refer to
Diagnostic Function - OBD-II Drive Cycle - Pattern 7 P.
13Ab-8.
(3)
Check the diagnostic trouble code (DTC).
Q:Is DTC P0106 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. Then go to Step 5.
NO:
The inspection is complete.
STEP 5. Test the OBD-II drive cycle.
(1)
Carry out a test drive with the drive cycle pattern. Refer to
Diagnostic Function - OBD-II Drive Cycle - Pattern 7 P.
13Ab-8.
(2)
Check the diagnostic trouble code (DTC).
Q:Is DTC P0106 set?
YES:
IRetry the troubleshooting.
NO:
The inspection is complete.

CIRCUIT OPERATION
⦆
A 5-volt voltage is supplied to the manifold absolute
pressure sensor power terminal (terminal No. 3)
from the ECM (terminal No. 44). The ground
terminal (terminal No. 2) is grounded with ECM
(terminal No. 46).
⦆
A voltage that is proportional to the intake manifold
pressure is sent to the ECM (terminal No. 45) from
the manifold absolute pressure sensor output
terminal (terminal No. 1).
TECHNICAL DESCRIPTION
⦆
The manifold absolute pressure sensor outputs a
voltage which corresponds to the intake manifold
pressure.
⦆
The ECM checks whether this voltage is within a
specified range.
DESCRIPTIONS OF MONITOR METHODS
Manifold absolute pressure sensor output voltage is
out of specified range.

lower for 2 seconds.
OBD-II DRIVE CYCLE PATTERN
Refer to Diagnostic Function - OBD-II Drive Cycle -
Pattern 7 P.13Ab-8.
TROUBLESHOOTING HINTS (The most likely
causes for this code to be set are: )
⦆
Manifold absolute pressure sensor failed.
⦆
Connector damage
⦆
Harness damage
⦆
