Subaru Legacy BN/BS (2015-2019) Service Manual / Engine (diagnostics)(h4do) / Diagnostic procedure with diagnostic trouble code (dtc) / Dtc p2119 throttle actuator "a" control throttle body range/performance

NOTE:

For the diagnostic procedure, refer to DTC P2101. Diagnostic Procedure with Diagnostic Trouble Code (DTC) > DTC P2101 THROTTLE ACTUATOR "A" CONTROL MOTOR CIRCUIT RANGE/PERFORMANCE

1. OUTLINE OF DIAGNOSIS

Judge as NG when the target opening angle and actual opening angle is mismatched or the current to motor is the specified duty or more for specified time continuously.

2. COMPONENT DESCRIPTION

(1)	Motor	(3)	Engine control module (ECM)	(4)	Drive circuit
(2)	Throttle position sensor

3. EXECUTION CONDITION

Secondary Parameters	Execution condition
Battery voltage	≥ 6.2 V
Electronic throttle control relay output	ON

4. GENERAL DRIVING CYCLE

Always perform the diagnosis continuously when the electronic throttle control is operating.

5. DIAGNOSTIC METHOD

Judge as NG if the criteria below are met.
