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

5.1~6.9 kΩ (when at 0 ºC)
2.0~3.0 kΩ (when at 20 ºC)
0.9~1.5 kΩ (when at 40 ºC)
0.40~0.78 kΩ (when at 60 ºC)
0.23~0.42 kΩ (when at 80 ºC)

(5) If the resistance deviates from the standard values, or if it does
not change, replace the air temperature sensor.
(6) Tighten the air temperature sensor to the specified torque.
Tightening torque: 14 ± N·m
4. Inspection of the oil feeder control valve
Checking the operation of the valve
(1) Disconnect the oil feeder control valve connector.
(2) Apply battery voltage across the terminals of the connector on
the oil feeder control valve side, and check that the sound of the
oil feeder control valve operating can be heard.
Caution
There is a chance that the coil may be damaged, so apply
the voltage in as short a time as possible.
Resistance across the terminals
(1) Remove the oil feeder control valve connector.
(2) Measure the resistance across the terminals of the connector on
the oil feeder control valve side.
Standard value: 6.9~7.9 kΩ (when at 20 ºC)
(3) If the resistance deviates from the standard value, replace the oil

Fitting guidelines



A 
Fitting the O-ring
Fit the O-ring into the O-ring groove at the end of the water inlet
pipe, and insert it into the water pump after moistening with water
the places where the O-ring will make contact with the water pump.
Caution
Ensure that absolutely no engine oil, or other type of grease,
gets onto the O-ring.

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
