INSPECTION PROCEDURE
HINT:
According to the DATA LIST displayed by the hand-held tester, you can read the value of the switch, sensor,
actuator and so on without parts removal. Reading the DATA LIST as the first step of troubleshooting is one
method to shorten labor time.
a. Turn the ignition switch off.
b. Connect the hand-held tester together with the CAN VIM (controller area network vehicle interface
module) to the DLC3.

HINT:
This test can be conducted when the vehicle speed is 58 km/h (36 mph) or more.
This test can be conducted with the 5th or 6th gear.
i. Lightly depress the accelerator pedal and check that the engine speed does not change abruptly.
HINT:
When changing the accelerator pedal opening angle while driving, if the engine speed does not change,
lock-up is on.
Slowly release, but not fully, the accelerator pedal in order to decelerate. (Fully releasing the pedal will
close the throttle valve and loc
k-up may be turned off automatically.)

1. Connect the hand-held tester (with CAN VIM) to the DLC3.
2. Turn the ignition switch ON.
3. Check that the MIL does not light up.
4. Check that, under the CURRENT DATA, THROTTLE POS (throttle valve opening percentage) is
within the standard value below.
Standard throttle valve opening percentage: 60% or more
If operation is not as specified, check the throttle position sensor, wiring and ECM (see DTC P0120,
P0122, P0123, P0220, P0222, P0223, P2135: THROTTLE/PEDAL POSITION SENSOR/SWITCH
