Series A
1. Check throttle position sensor.
a) (4A-FE with automatic transmission) Apply vacuum to the throttle damper.
b) Insert a 0.4 or 0.9 mm thick feeler gauge between the throttle stop adjusting screw and lever.
V) Using an ohmmeter, measure the resistance between the respective terminals of the sensor connector at various throttle positions.
3S-FE, 4S-FE
Except 4S-FE with manual transmission
1. Check throttle position sensor.
A) Insert a 0.4 or 0.9 mm thick feeler gauge between the throttle stop adjusting screw and lever.
b) Using an ohmmeter, measure the resistance between the respective terminals of the sensor connector at various throttle positions.
4S-FE with manual transmission
1. Check the continuity between the throttle connector terminals by inserting a 0.70 and 0.90 mm thick feeler gauge between the adjusting screw and the throttle lever.
Make an angle template as shown in the figure and use it to set the throttle opening angle (19°or 29°). Measure resistance between leads "PSW" And "E2".
