INSPECTION AFTER REMOVAL
Output Rod Length Inspection
1. With a handy vacuum pump, apply vacuum pressure of −66.7
kPa (−500 mmHg, −19.70 inHg, –0.667 bar) to the brake
booster.
2. Check the output rod length (A).
Input Rod Length Inspection
1. Loosen the lock nut (1) and adjust the input rod (2) to the speci-
fied length (B).
2. Tighten the lock nut to the specified torque.
INSPECTION AFTER INSTALLATION
Operation
Depress the brake pedal several times at 5-second intervals with the
engine stopped. Start the engine with the brake pedal fully
depressed. Check that the clearance between brake pedal and dash
lower pane decreases.
NOTE:
A slight impact with a small click may be felt on the pedal when the
brake pedal is fully depressed. This is a normal phenomenon due to
the brake system operation.

REMOVAL
Remove the vacuum hose and tube.
INSTALLATION
Note the following, install the vacuum hose and tube.
 Because vacuum hose contains a check valve, it must be installed in the correct position. Refer to the stamp
to confirm correct installation. Brake booster will not operate normally if the hose is installed in the wrong
direction.
 When installing vacuum hose, insert it until its tip reaches the
back-end of length (A) or further as shown in the figure.
- Face the marking side up when assembling of vacuum hose. (For
both side of vacuum hose of intake manifold side.)
- Face the marking side vehicle front when assembling of vacuum
hose. (For both side of vacuum hose of brake booster side)
CAUTION:
Never use lubricating oil during assembly.

< FUNCTION DIAGNOSIS >[VQ25DE, VQ35DE]
MULTIPORT FUEL INJECTION SYSTEM
*1: This sensor is not used to control the engine system under normal conditions.
*2: This signal is sent to the ECM through CAN communication line.
*3: ECM determines the start signal status by the signals of engine speed and battery voltage.
SYSTEM DESCRIPTION
The amount of fuel injected from the fuel injector is determined by the ECM. The ECM controls the length of
time the valve remains open (injection pulse duration). The amount of fuel injected is a program value in the
ECM memory. The program value is preset by engine operating conditions. These conditions are determined
by input signals (for engine speed and intake air) from the crankshaft position sensor (POS), camshaft position
sensor (PHASE) and the mass air flow sensor.
VARIOUS FUEL INJECTION INCREASE/DECREASE COMPENSATION
In addition, the amount of fuel injected is compensated to improve engine performance under various operat-
ing conditions as listed below.

 When starting the engine
 During acceleration

ON BOARD DIAGNOSTIC (OBD) SYSTEM
This DTC number is clarified in Diagnostic Test Mode II (SELF-DIAGNOSTIC RESULTS)
Diagnostic Test Mode II — Self-diagnostic Results
In this mode, the DTC and 1st trip DTC are indicated by the number of blinks of the MI as shown below.
The DTC and 1st trip DTC are displayed at the same time. If the MI does not illuminate in diagnostic test mode
I (Malfunction warning), all displayed items are 1st trip DTCs. If only one code is displayed when the MI illumi-
nates in diagnostic test mode II (SELF-DIAGNOSTIC RESULTS), it is a DTC; if two or more codes are dis-
played, they may be either DTCs or 1st trip DTCs. DTC No. is same as that of 1st trip DTC. These unidentified
codes can be identified by using the CONSULT-III or GST. A DTC will be used as an example for how to read
a code.
A particular trouble code can be identified by the number of four-digit numeral flashes as per the following.
The length of time the 1,000th-digit numeral flashes on and off is 1.2 seconds consisting of an ON (0.6-sec-
onds) - OFF (0.6-seconds) cycle.
The 100th-digit numeral and lower digit numerals consist of a 0.3-seconds ON and 0.3-seconds OFF cycle.
A change from one digit numeral to another occurs at an interval of 1.0-second OFF. In other words, the later
numeral appears on the display 1.3 seconds after the former numeral has disappeared.
A change from one trouble code to another occurs at an interval of 1.8-seconds OFF.
In this way, all the detected malfunctions are classified by their DTC numbers. The DTC 0000 refers to no mal-
function. (See EC-389, "
DTCIndex")
How to Switch Diagnostic Test Mode
NOTE:
It is better to count the time accurately with a clock.
MI Condition
ON When the malfunction is detected.
OFF No malfunction.

FUEL INJECTOR
FUEL INJECTOR
DescriptionINFOID:0000000003856839
The fuel injector is a small, precise solenoid valve. When the ECM
supplies a ground to the fuel injector circuit, the coil in the fuel injec-
tor is energized. The energized coil pulls the ball valve back and
allows fuel to flow through the fuel injector into the intake manifold.
The amount of fuel injected depends upon the injection pulse dura-
tion. Pulse duration is the length of time the fuel injector remains
open. The ECM controls the injection pulse duration based on
engine fuel needs.
Component Function CheckINFOID:0000000003856840
1.INSPECTION START
Turn ignition switch to START.
Are any cylinders ignited?
YES >> GO TO 2.
NO >> Go to EC-334, "
Diagnosis Procedure".
2.CHECK FUEL INJECTOR FUNCTION
With CONSULT-III
1. Start engine.
2. Perform “POWER BALANCE” in “ACTIVE TEST” mode with CONSULT-III.
3. Check that each circuit produces a momentary engine speed drop.
Without CONSULT-III
1. Start engine.
2. Listen to each fuel injector operating sound.
Is the inspection result normal?
YES >> INSPECTION END
NO >> Go to EC-334, "
Diagnosis Procedure".
Diagnosis ProcedureINFOID:0000000003856841
1.CHECK FUEL INJECTOR POWER SUPPLY CIRCUIT
1. Turn ignition switch OFF.
2. Disconnect fuel injector harness connector.
3. Turn ignition switch ON.
4. Check the voltage between fuel injector harness connector and ground.

3. Hold the hexagonal part in center of drive belt auto-tensioner
pulley with a box wrench securely. Then move the wrench han-
dle in the direction of arrow (loosening direction of drive belt).
CAUTION:
 Avoid placing hand in a location where pinching may
occur if the holding tool accidentally comes off.
 Never loosen the hexagonal part in center of drive belt
auto-tensioner pulley (Never turn it counterclockwise). If
turned counterclockwise, the complete drive belt auto-
tensioner must be replaced as a unit, including the pulley.
4. Insert a rod approximately 6 mm (0.24 in) in diameter such as
short-length screwdriver into the hole (A) of the retaining boss to
fix drive belt auto-tensioner pulley.
 Keep drive belt auto-tensioner pulley arm locked after drive belt is removed.
5. Loosen drive belt from water pump pulley in sequence, and remove it.
INSTALLATION
1. Hook drive belt on to all pulleys except for drive belt auto-tensioner pulley, and then onto drive belt auto-
tensioner pulley finally.
CAUTION:
 Confirm drive belt is completely set to pulleys.
 Check for engine oil, working fluid and engine coolant are not adhered to drive belt and each
pulley groove.
2. Release drive belt auto-tensioner, and apply tension to drive belt.
3. Turn crankshaft pulley clockwise several times to equalize tension between each pulley.
4. Confirm tension of drive belt at indicator is within the possible use range. Refer to EM-12, "
Exploded
View".
