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 |
12 V battery system voltage | 6.2 V |
Throttle motor relay command | ON |
4. GENERAL DRIVING CYCLE
Always perform the diagnosis continuously when the electronic throttle control is operating.
5. DIAGNOSTIC METHOD
Judge as OK and clear the NG when the malfunction criteria below are met.
Diagnosis 1
Malfunction Criteria | Threshold Value |
Output duty to drive circuit | ≥ 95 % |
Time Needed for Diagnosis:
• Engine speed ≥ 500 rpm: 2000 ms
• Engine speed < 500 rpm: 5000 ms
Diagnosis 2
Malfunction Criteria | Threshold Value |
Difference between target opening angle and actual opening angle | Within NG range of Details of Judgment value |
Time Needed for Diagnosis:
• Engine speed ≥ 500 rpm: Refer to Details of Judgment time.
• Engine speed < 500 rpm: 5000 ms
