ELECTRIC SHIFT PROGRAM (ESP/FE model)
2. TP Sensor Inspection 1 at ECM Connector
Disconnect the angle sensor 3P connector
(page 22-18).
Disconnect the ECM 33P black connector.
Measure the resistance between the Black/red
and Green/blue wire terminals of the wire har-
ness side connector using the special tool.
TOOL:
Pin probe (Male) 07ZAJ-RDJA110
STANDARD: 4 - 6 k£2 (20°C/ 68°F)
Is the resistance within the specified range?
NO - GO TO STEP 4.
YES - GO TO STEP 3.
3. TP Sensor Inspection 2 at ECM Connector
Check that the resistance between the Yellow/
black and Green/blue terminals of the wire har-
ness side connector varies while operating the
throttle lever.
From fully closed position to fully open position:
Resistance increases
From fully open position to fully closed position:
Resistance decreases
Does the resistance vary properly?
NO - GO TO STEP 7.
YES - GO TO STEP 9.
4. TP Sensor Resistance Inspection 1
Disconnect the TP sensor connector.
Measure the resistance between the Black/red
and Green/blue terminal of the TP sensor.
Is the resistance within 4-6ki2 (20°C/68°F)?
NO - Faulty TP sensor.
YES - GO TO STEP 5.
5. TP Sensor Input Voltage Inspection
Connect the ECM 33P connector.
Turn the ignition switch to "ON".
Measure the input voltage between the Black/red
(+) and Green/blue (-) terminal of the wire har-
ness side TP sensor connector.
Is there 4.7- 5.3 V?
NO - Repair open or short circuit in the Black/
red wire.
YES - GO TO STEP 6.
