DTC Description

DTC DETECTION LOGIC
POSSIBLE CAUSE
• Harness or connectors (APP sensor 1 circuit is open or shorted.)
• Accelerator pedal position sensor (APP sensor 1)
FAIL-SAFE
• The ECM controls the electric throttle control actuator in regulating the throttle opening in order for the idle
position to be within +10 degrees.
• The ECM regulates the opening speed of the throttle valve to be slower than the normal condition. So, the
acceleration will be poor.
DTC CONFIRMATION PROCEDURE
1.
CHECK DTC PRIORITY
If DTC P2122 or P2123 is displayed with DTC P0643, first perform the trouble diagnosis for DTC P0643.
Is applicable DTC detected?
YES
>> Perform diagnosis of applicable. Refer to
.
NO
>> GO TO 2.
2.
PRECONDITIONING
