Manifold Absolute Pressure (MAP) Sensor
Inspection
1) Remove air cleaner assembly.
2) Disconnect connector from MAP sensor.
3) Remove MAP sensor.
4) Arrange 3 new 1.5 V batteries (2) in series (check
that total voltage is 4.5 – 5.0 V) and connect its
positive terminal to "Vin" terminal of sensor and
negative terminal to "Ground" terminal. Then check
voltage between "Vout" and "Ground". Also, check if
voltage reduces when vacuum is applied up to 400
mmHg by using vacuum pump (3).
If check result is not satisfactory, replace MAP
sensor (1).

Engine Electrical Devices:
5) Install MAP sensor securely.
6) Connect MAP sensor connector securely.
7) Install air cleaner assembly.
Throttle Position (TP) Sensor On-Vehicle
Inspection
1) Disconnect negative cable at battery.
2) Disconnect TP sensor connector.
3) Using ohmmeter, check resistance between
terminals under each condition.
If check result is not satisfactory, replace TP sensor.
TP sensor resistance
Between terminals "1" and "3": 4.0 – 6.0 k
Between terminals "2" and "3": 20
varying according to throttle valve opening
NOTE:
There should be more than 2 k resistance
difference between when throttle valve is at
idle position and when it is fully open.

2. Output voltage terminal
3. Ground terminal
4) Connect TP sensor connector securely.
5) Connect negative cable to battery.
