Fail-safe mode continues until a pass condition is detected, and the engine switch is then turned off.

INSPECTION PROCEDURE
HINT
- Read freeze frame data using the Techstream. The ECM records vehicle and driving condition information as freeze frame
data the moment a DTC is stored. When troubleshooting, freeze frame data can help determine if the vehicle was moving or
stationary, if the engine was warmed up or not, if the air fuel ratio was lean or rich, and other data from the time the
malfunction occurred.
- The throttle actuator current (Throttle Motor Current) and the throttle actuator duty ratio (Throttle Motor Duty (Open) /
Throttle Motor Duty (Close)) can be read using the Techstream. However, the ECM shuts off the throttle actuator current
when the electronic throttle control system malfunctions.
PROCEDURE
1. INSPECT THROTTLE WITH MOTOR BODY ASSEMBLY (RESISTANCE OF THROTTLE ACTUATOR)
(a) Disconnect the throttle with motor body assembly connector.
(b) Measure the resistance according to the value(s) in the table below.
Standard Resistance:

(c) Reconnect the throttle with motor body assembly connector.
NG -- REPLACE THROTTLE WITH MOTOR BODY ASSEMBLY See: Powertrain Management/Fuel Delivery and Air
Induction/Throttle Body/Service and Repair/Removal
OK -- Continue to next step.
2. CHECK HARNESS AND CONNECTOR (THROTTLE WITH MOTOR BODY ASSEMBLY - ECM)
(a) Disconnect the throttle with motor body assembly connector.
