INSPECTION PROCEDURE
HINT:
Read freeze frame data using the hand−held tester or the OBD II scan tool. Freeze frame data records the
engine conditions when a malfunction is detected. When troubleshooting, freeze frame data can help deter-
mine if the vehicle was running or stopped, if the engine was warmed up or not, if the air−fuel ratio was lean
or rich, as well as other data from the time when a malfunction occurred.
Hand−held tester:
1 Connect hand−held tester, and read the voltage for accelerator pedal position
sensor data.
