(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.
