13A-29MPI – TROUBLESHOOTING, ON-VEHICLE SERVICING
•Example 2
Waveform characteristics
The waveform is displaced to the left or the right.
Cause of the problem
The timing belt is loose
There is an abnormality in the fuel pump camshaft
On-vehicle servicing
1. Adjusting standard engine revolutions
when idling
The standard engine revolutions when idling have been
changed. All other servicing requirements are the same as
before.
Standard engine revolutions when idling: 800 ± 50 r/min

3. Inspection of the air temperature sensor
(1) Disconnect the air temperature sensor connector.
(2) Measure the resistance across the terminals of the air
temperature sensor connector.
Standard values:
13~18 kΩ (when at -20 ºC)
5.1~6.9 kΩ (when at 0 ºC)

Removal guidelines
 
A


Removal of the delivery pipe, the injector and the fuel
pressure regulator ASSY
Remove the deliver pipe, with the injector and the fuel pressure
regulator intact.
Caution
When removing the delivery pipe, be careful not to drop the
injector.
Fitting guidelines



A 

Connecting the O-ring and the fuel high pressure hose
1. Apply a small quantity of fresh engine oil to the O-ring, and
insert it into the delivery pipe without damaging the O-ring.
2. Check that the high pressure hose can be turned smoothly. If it
cannot be turned smoothly there is a possibility that it is biting
into the O-ring, so remove the high pressure hose and check for
any damage to the O-ring. If the O-ring is undamaged, reinsert it
into the delivery pipe and check once more whether the hose
can be turned smoothly.
3. Tighten the mounting bolt to the specified torque.
Tightening torque: 5.0 ± 1.0 N·m

Removal guidelines
 
A



Removing the delivery pipe, the injector, and the fuel
pressure regulator ASSY
Loosen the bolts holding it in place, slightly dislodge all of the
components and make space for the alternator to be removed.
 
B


Removing the drive belt
The following procedures are necessary because a serpentine drive
system with auto-tensioner has been installed.
1. Insert a 12.7sq spinner handle into the auto-tensioner hole, and
turn the auto-tensioner in an anti-clockwise direction until it
reaches the stopper.
2. Align the A hole and the B hole, hold them in place by inserting
an L-shaped hexagonal Allen Key, and remove the drive belt.
Caution
If planning to re-use the drive belt, ensure that it will be
refitted the same way round, by marking the back of the belt
with chalk arrows indicating the direction of movement.
 
C


Removing the alternator
Push the whole engine up using a garage jack, and remove the
alternator from above.
