DTC P2109 00: TP Sensor Minimum Stop Range/Performance Problem: Notes

DTC P2109 00 DETECTION CONDITIONS AND POSSIBLE CAUSES (SKYACTIV-G 2.0, SKYACTIV-G 2.5)

DTC P2109:00	TP sensor minimum stop range/performance problem
DETECTION CONDITION	If the fully-close throttle position is 5.1 ° or lower, or 15.9 ° or more (even though fully-closed throttle position learning is finished), the PCM determines there is a malfunction. Diagnostic support note This is a continuous monitor (CCM). The check engine light illuminates if the PCM detects the above malfunction condition during the first drive cycle. FREEZE FRAME DATA (Mode 2)/Snapshot data is available. DTC is stored in the PCM memory.
FAIL-SAFE FUNCTION	Restricts the upper limit of the engine speed. Stops the drive-by-wire control (throttle valve is open at approx. 8 ° by return spring force).
POSSIBLE CAUSE	Throttle body connector or terminals malfunction Short to ground in wiring harness between the following terminals: Throttle body terminal E-PCM terminal 1CG Throttle body terminal F-PCM terminal 1CC PCM connector or terminals malfunction Short to power supply in wiring harness between the following terminals: Throttle body terminal E-PCM terminal 1CG Throttle body terminal F-PCM terminal 1CC Open circuit in wiring harness between the following terminals: Throttle body terminal E-PCM terminal 1CG Throttle body terminal F-PCM terminal 1CC Throttle valve malfunction Throttle valve actuator malfunction PCM malfunction
