Diagnostic Procedure
1
CHECK VEHICLE SPEED SENSOR INPUT SIGNAL CIRCUIT FOR OPEN AND SHORT
1. Turn ignition switch “OFF”.
2. Disconnect ECM harness connector and combination meter harness connector.
3. Check harness continuity between ECM terminal 26 and combination meter terminal 26. Refer to Wiring Diagram.
Continuity should exist.
4. Also check harness for short to ground and short to power.

Description
The accelerator switch is installed to the accelerator pedal assem-
bly. The switch senses accelerator position and sends an ON-OFF
signal to the ECM. The ECM uses the signal to control the fuel cut
operation at deceleration for better fuel efficiency.

DTC Confirmation Procedure
WITH CONSULT-II
1) Turn ignition switch “ON”.
2) Select “DATA MONITOR” mode with CONSULT-II.
3) Fully depress and fully release accelerator pedal, and wait 15
seconds.
4) Repeat step 3 at least 29 times.
5) If DTC is detected, go to “Diagnostic Procedure”, EC-107.
WITHOUT CONSULT-II
1) Turn ignition switch “ON”.
2) Fully depress and fully release accelerator pedal, and then wait
15 seconds.
3) Repeat step 2 at least 29 times.
4) Turn ignition switch “OFF”, wait at least 5 seconds and then turn
“ON”.
5) Perform “Diagnostic Test Mode II (Self-diagnostic results)” with
ECM.
6) If DTC is detected, go to “Diagnostic Procedure”, EC-107.
