(9) If not as specified, check related wiring
harness. If they are okay, replace the throttle
body.
9. If the
SSTs
(NGS tester) are used, check in the
following order.
(1)
Connect the
SSTs
(NGS tester) to the data
link connector.
(2) Verify that the throttle valve is at the closed
throttle position.
(3) Turn the ignition switch to ON.
(4) Select the “ PID/DATA MONITOR AND
RECORD” function on the NGS display and
press TRIGGER.
(5) Select “TP V” on the NGS tester display and
press START. The NGS tester measures and
shows the voltage.

1. If the SST (104 Pin Breakout Box) are used,
check in the following order.
(1) Remove the PCM. (Refer to 01-40B
