P2100, P2103 THROTTLE CONTROL MOTOR RELAY

DTC Description

INFOID:0000000010986455

DTC DETECTION LOGIC

POSSIBLE CAUSE

DTC P2100

• Harness or connectors (Throttle control motor relay circuit is open.)
• Throttle control motor relay

DTC P2103

• Harness or connectors (Throttle control motor relay circuit is shorted.)
• Throttle control motor relay

FAIL-SAFE

ECM stops the electric throttle control actuator control, throttle valve is maintained at a fixed opening (approx.
5 degrees) by the return spring.

DTC CONFIRMATION PROCEDURE

1.

PRECONDITIONING

If DTC Confirmation Procedure has been previously conducted, always perform the following procedure
before conducting the next test.
