TCM SELF-DIAGNOSTIC PROCEDURE (NO TOOLS)NJAT0352S06PreparationNJAT0352S06011. Turn ignition switch to ªOFFº position.
2. Connect the handy type vacuum pump to the throttle opener
and apply vacuum þ25.3 kPa (þ253 mbar, þ190 mmHg, þ7.48
inHg). (If throttle opener is equipped)
3. Disconnect the throttle position switch harness connector.
4. Turn ignition switch to ªONº position.
5. Check continuity of the closed throttle position switch.
Continuity should exist.
(If continuity does not exist, check throttle opener and
closed throttle position switch. Then increase vacuum
until closed throttle position switch shows continuity.)
6. Go to ªSelf-diagnostic procedure (Without CONSULT-II)º.
