CIRCUIT DESCRIPTION
The fuel injectors are located on the intake manifold.
They inject fuel into the cylinders based on the signals from the ECM.
Reference: Inspection using oscilloscope
With the engine idling, check the waveform between terminals #1 to #4 and E01 of the ECM connectors.

The correct waveform is as shown in the diagram below.

CIRCUIT LOW INPUT
DTC P0108 MANIFOLD ABSOLUTE
PRESSURE/BAROMETRIC PRESSURE
CIRCUIT HIGH INPUT
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.
If the ECM detects the DTC ºP0105, P0107 or P0108º, it oper-
ates the fail±safe function, keeping the ignition timing and fuel
injection volume constant and making it possible to drive the ve-
hicle.

INSPECTION PROCEDURE
HINT:

If different DTCs related to different systems that have terminal E2 as the ground terminal are output
simultaneously, terminal E2 may be open.

Read freeze frame data using the hand±held tester. Freeze frame data records the engine conditions
when a malfunction is detected. When troubleshooting, it is useful for determining whether the vehicle
was running or stopped, the engine was warmed up or not, the air±fuel ratio was lean or rich, etc. at
the time of the malfunction.
1 READ VALUE OF HAND±HELD TESTER(INTAKE MANIFOLD ABSOLUTE
PRESSURE)
(a) Connect the hand±held tester to the DLC3.
(b) Turn the ignition switch ON.
(c) Push the hand±held tester main switch ON.
(d) Select the item ºDIAGNOSIS / OBD/MOBD / DATA LIST / ALL / MAPº and read its value displayed on
the hand±held tester.
