INSTALLATION
1) Arrange 3 new 1.5V batteries in series (2) (check that total volt-
age is 4.5 – 5.0 V) and connect its positive terminal to “a” termi-
nal of sensor (1) and negative terminal to “c” terminal. Then
check voltage between “b” and “c” by using digital type voltme-
ter (4).
Also, check if voltage reduces when vacuum is applied up to
400mmHg by using vacuum pump (3).
Output voltage (Vin voltage 4.5 – 5.0 V, ambient temp.

TP SENSOR
INSPECTION
1) Disconnect negative cable at battery and coupler from TP sen-
sor.
2) Using ohmmeter, check resistance between terminals under
each condition given in table below.
NOTE:
There should be more than 1.5 k
resistance difference be-
tween when throttle valve is at idle position and when it is
fully open.
If check result is not satisfactory, replace TP sensor.
3) Connect TP sensor coupler securely.
4) Connect negative cable to battery.
