Using the DATA LIST displayed by the hand±held tester, you can read the value of the switches, sensors,
actuators and so on without parts removal. Reading the DATA LIST as a first step of troubleshooting is one
method to shorten diagnostic time.
NOTICE:
The values given below for ºNormal Conditionº are representative valu\
es. A vehicle may still be nor-
mal even if its value differs from those listed here. Do not solely depend \
on the ºNormal Conditionº
here when deciding whether a part is faulty or not.
(a) Warm up the engine.
(b) Turn the ignition switch OFF.
(c) Connect the hand±held tester to the DLC3.
(d) Turn the ignition switch ON.
(e) Push the ºONº button of the hand±held tester.
(f) Select the item ºDIAGNOSIS / OBD/MOBD / DATA LISTº.

HINT:

If DTCs ºP0105, P0107,and P0108º are output simultaneously, manifold absolute pressure sensor
circuit may be open or short. Perform the troubleshooting of DTC ºP0105, P01\
07 or P0108º first.

CIRCUIT DESCRIPTION
By a built±in sensor unit, the manifold absolute pressure sensor
detects the intake manifold pressure as a voltage. The ECM
then determines the basic injection duration and basic ignition
advance angle based on this voltage.
Since the manifold absolute pressure sensor does not use the
atmospheric pressure as a criterion, but senses the absolute
pressure inside the intake manifold (the pressure in proportion
to the preset absolute vacuum 0), it is not influenced by fluctua-
tions in the atmospheric pressure due to high altitude and other
factors. This permits it to control the air fuel ratio at the proper
level under all conditions.
