3. THROTTLE BODY ASSY
(a) Resistance inspection
(1) Using an ohmmeter, measure the resistance be-
tween terminals.
Resistance: 0.3 – 100 Ω at 20C (68F)
4. E.F.I. THROTTLE POSITION SENSOR
(a) Resistance inspection.
(1) Using an ohmmeter, measure the resistance be-
tween terminals 1 (VC) and 4 (E2).
Resistance: 1.2 – 3.2 kΩ
5. E.F.I. ENGINE COOLANT TEMPERATURE SENSOR
(a) Resistance inspection.
(1) Using an ohmmeter, measure the resistance be-
tween each terminal.
Resistance:
Approx. 20C (68F) 2.32 – 2.59 kΩ
Approx. 80C (176F) 0.310 – 0.326 kΩ
NOTICE:
In case of checking the water temperature sensor in the wa-
ter, be careful not to allow water to go into the terminals,
and after checking, wipe out the sensor.
6. KNOCK CONTROL SENSOR
(a) Continuity inspection.
(1) Using an ohmmeter, check that no continuity exists
between the terminal and body.
