If the Electronic Throttle Control System (ETCS) has a mal-
function, the ECM cuts off current to the throttle control
motor. The throttle control valve returns to a predetermined
opening angle (approximately 16) by the force of the return
spring. The ECM then adjusts the engine output by control-
ling the fuel injection (intermittent fuel-cut) and ignition tim-
ing in accordance with the accelerator pedal opening angle
to enable the vehicle to continue at a minimal speed.
If the accelerator pedal is depressed firmly and slowly, the
vehicle can be driven slowly. If the accelerator pedal is
depressed quickly, the vehicle may speed up and slow
down erratically.
ºPassº condition is detected and then the ignition switch is
turned OFF.

The accelerator pedal position sensor has two (main and
sub) sensor circuits. If a malfunction occurs in either of the
sensor circuits, the ECM detects the abnormal signal volt-
age difference between the two sensor circuits and
switches to limp mode. In limp mode, the remaining circuit
is used to calculate the accelerator pedal opening to allow
the vehicle to continue driving.
If both circuits malfunction, the ECM regards the opening
angle of the accelerator pedal to be fully closed. In this
case, the throttle valve will remain closed as if the engine is
idling.
ºPassº condition is detected and the ignition switch is turned
OFF.
5. CHECK FOR INTERMITTENT PROBLEMS
Hand-held tester only:
Inspect the vehicle's ECM using check mode. Intermittent problems are easier to detect when the ECM is
in check mode with hand-held tester. In check mode, the ECM uses 1 trip detection logic, which has a higher
sensitivity to malfunctions than normal mode (default), which uses 2 trip detection logic.
(a) Clear the DTCs. (See step 2)
(b) Set the check mode. (See step 3)
(c) Perform a simulation test (See page IN-26).
(d) Check the connector and terminal (See page IN-36).
(e) Wiggle the harness and connector (See page IN-36).

7. DATA LIST
HINT:
Using the hand-held tester DATA LIST allows switch, sensor, actuator and other item values to be read with-
out removing any parts. Reading the DATA LIST early in troubleshooting is one way to shorten labor time.
NOTICE:
In the table below, the values listed under ºNormal Conditionº are reference values. Do not depend
solely on these reference values when deciding whether a part is faulty or not.
(a) Warm up the engine.
(b) Turn the ignition switch OFF.
(c) Connect the hand-held tester or the OBD II scan tool to the DLC3.
(d) Turn the ignition switch ON.
(e) Push the ºONº button of the hand-held tester.
(f) Enter the following menus: DIAGNOSIS / ENHANCED OBD II / DATA LIST.
(g) According to the display on tester, read the ºDATA LISTº.
