FAIL-SAFE CHART
If any of the following DTCs are set, the ECM enters fail-safe
mode to allow the vehicle to be driven temporarily.
HINT:
*: The vehicle can be driven slowly when the accelerator
pedal is depressed firmly and slowly. If the accelerator pedal
is depressed quickly, the vehicle may speed up and slow
down erratically.

System (ETCS)ECM cuts off throttle actuator
current and throttle valve returned
to 6
throttle position by return
spring.
ECM then adjusts engine output
by controlling fuel injection
(intermittent fuel-cut) and ignition
timing in accordance with
accelerator pedal opening angle
to allow vehicle to continue at
minimal speed*.Pass condition detected and then
ignition switch turned OFF
P0327 and P0328 Knock SensorECM sets ignition timing to
maximum retard.Ignition switch OFF

P2120, P2121, P2122, P2123,
P2125, P2127, P2128 and P2138Accelerator Pedal Position (APP)
SensorAPP sensor has 2 sensor circuits:
Main and Sub.
If either circuit malfunctions, ECM
controls engine using other
circuit.
If both circuits malfunction, ECM
regards accelerator pedal as
being released. As result, throttle
valve closed and engine idles.Pass condition detected and then
ignition switch turned OFF
