Subsection 02 (ELECTRONIC FUEL INJECTION (EFI))

must return freely to the rest position (slightly
opened).

1. Push here to close
If throttle plate does not move smoothly or does
not return freely to the position, the problem is
mechanical. Check for salt accumulation on throt-
tle plate shaft. It may also be an actuator or gear
problem. Replace throttle body as necessary.
If throttle plate operates normally, the problem
is electrical. Check throttle actuator (ETA) wiring
continuity, throttle position sensor (TPS) and
throttle accelerator sensor (TAS).
WARNING
Replace throttle body when throttle plate
does not return properly.
