REASSEMBLY SERVICE POINTS

THROTTLE POSITION SENSOR
1.
Position the throttle position sensor on the throttle body
along the dotted line as shown in the illustration.
2.
Rotate the throttle position sensor anticlockwise as shown
in the illustration, and then tighten the screws.
3.
Measure resistance value between terminal Nos. 1 (sensor
power supply) and 2 (throttle position sensor 1st-channel
output) as well as 1 (sensor power supply) and 4 (throttle
position sensor 2nd-channel output).
Normal condition
Open the throttle valve slowly
from the idle position to
full-open position.
Resistance value changes
smoothly in response to
throttle valve opening angle.
4.
If the resistance value does not change smoothly, replace
the throttle position sensor.

GENERAL
OUTLINE OF CHANGES
The service procedures have been established to describe revised sections due to the changed items
shown below.
On-board Diagnostics System has been adopted, diagnostic items have been expanded, and diagnostic
code numbering system has been changed.
Non-distributor two-coiled ignition system has been adopted.
Crank angle sensor attached to the crank shaft has been adopted.
Camshaft position sensor has been added.
Ignition failure sensor has been added.
Intake air temperature sensor built in the vacuum sensor (manifold absolute pressure sensor) has
been adopted.
Oxygen sensor (front, rear) has been changed.
Ignition timing adjustment terminal has been abolished.
GENERAL INFORMATION
SELF-DIAGNOSIS FUNCTION
The following functions have been added.
The engine-ECU records the engine operating condition when the diagnosis code is set.
This data is called “freeze frame” data.
This data can be read by using the MUT-
II
, are can then be used in simulation tests for troubleshooting.
