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 be helpful in determining whether the vehicle was running or stopped, whether the engine was warmed up or not, whether the air fuel ratio was lean or rich, as well as other data recorded at the time of a malfunction.
• The throttle actuator current [Throttle Motor Current] and the throttle actuator duty ratio Throttle Motor Open Duty / Throttle Motor Close Duty can be read using the Techstream. However, the ECM shuts off the throttle actuator current when the electronic throttle control system malfunctions.
