DTC P2119:00 [PCM (SKYACTIV-X)]

System malfunction location	Throttle valve actuator control throttle body range/performance problem
Detection condition	• The PCM compares the actual TP with initial setting TP when the ignition is switched off. If the actual TP is higher than the initial setting TP, the PCM determines that there is a throttle valve return spring malfunction.
Fail-safe	• Restricts the upper limit of the engine speed.
Possible cause	• Throttle body connector or terminals malfunction • PCM connector or terminals malfunction • Drive-by-wire control malfunction • Throttle body (return spring) malfunction • PCM malfunction
System wiring diagram	• Not applicable
Connector diagram	• Not applicable

Yes	Perform repair or diagnosis according to the available information. • If the vehicle is not repaired, go to the next step.
No	Go to the next step.
3	INSPECT FOR OTHER RELATED DTCs • Perform the DTC inspection for the PCM. (See DTC INSPECTION.) • Are any other DTCs displayed?	Yes	Repair the malfunctioning location according to the applicable DTC troubleshooting. (See DTC TABLE [PCM (SKYACTIV-X)].)
No	Go to the next step.
4	INSPECT THROTTLE BODY CONNECTOR FOR MALFUNCTION • Inspect the applicable connector and terminal. (See CONNECTOR INSPECTION.) • Are the connector and terminal normal?	Yes	Go to the next step.
No	Repair or replace the malfunctioning location and perform the repair completion verification.
5	INSPECT PCM CONNECTOR FOR MALFUNCTION • Inspect the applicable connector and terminal. (See CONNECTOR INSPECTION.) • Are the connector and terminal normal?	Yes	Go to the next step.
No	Repair or replace the malfunctioning location and perform the repair completion verification.
6	INSPECT DRIVE-BY-WIRE CONTROL SYSTEM OPERATION • Perform the Drive-by-wire Control System Inspection. (See ENGINE CONTROL SYSTEM OPERATION INSPECTION [SKYACTIV-X].) • Is there any malfunction?	Yes	Repair or replace the malfunctioning location and perform the repair completion verification.
No	Go to the next step.
7	INSPECT THROTTLE BODY FOR MALFUNCTION • Inspect the applicable part. (See THROTTLE BODY INSPECTION [SKYACTIV-X 2.0].) • Is the part normal?	Yes	Go to the next step.
No	Repair or replace the malfunctioning location and perform the repair completion verification. (See INTAKE-AIR SYSTEM REMOVAL/INSTALLATION [SKYACTIV-G (WITHOUT CYLINDER DEACTIVATION (E))].)
Repair completion verification 1	VERIFY THAT VEHICLE IS REPAIRED • Install/connect the part removed/disconnected during the troubleshooting procedure. • Clear the DTC recorded in the memory. (See CLEARING DTC.) • Replicate the vehicle conditions at the time the DTC was detected using the following procedure. ― Switch the ignition ON (engine off) and wait for 1 min or more. ― Switch the ignition off. ― Perform the KOER self test. (See DTC INSPECTION.) • Perform the DTC inspection for the PCM. (See DTC INSPECTION.) • Is the same Pending DTC present?	Yes	Refer to the controller area network (CAN) malfunction diagnosis flow to inspect for a CAN communication error. (See CONTROLLER AREA NETWORK (CAN) MALFUNCTION DIAGNOSIS FLOW [(E)].) If the CAN communication is normal, perform the diagnosis from Step 1. • If the malfunction recurs, replace the PCM, then go to the next step. (See PCM REMOVAL/INSTALLATION [SKYACTIV-X 2.0].)
No	Go to the next step.
Repair completion verification 2	VERIFY IF OTHER DTCs DISPLAYED • Perform the DTC inspection. (See DTC INSPECTION.) • Are any other DTCs displayed?	Yes	Repair the malfunctioning location according to the applicable DTC troubleshooting.
No	DTC troubleshooting completed.
