DTC P2101: Throttle Valve Control Servo Magneto Malfunction
OPERATION Controls the current that is applied from the engine-A/T-ECU (terminals No. 133, No. 141) to the electronically controlled throttle valve (terminals No. 1, No. 2).
FUNCTION Engine-A/T-ECU check whether the throttle valve control servo magneto failed.
TROUBLE JUDGMENT Check Condition Battery positive voltage is 8.3 V or higher. Judgement Criteria The coil temperature of the throttle actuator control motor is 180°C or higher for 0.8 second. <Vehicles for Hong kong> Communication error or excessive heating is received in the intelligence power device for 0.8 second. <Vehicles except for Hong kong>
PROBABLE CAUSE Failed throttle valve control servo. Open/short circuit in throttle valve control servo circuit or lose connector contact. Failed engine-A/T-ECU
| DIAGNOSIS PROCEDURE
| STEP 1. Connector check: B-33 electronically controlled throttle valve connector
| Q: Is the check result normal? YES: Go to Step 2 . NO: Repair.
| STEP 2. Perform resistance measurement at B-33 electronically controlled throttle valve connector.
| Disconnect connector, and measure at electronically controlled throttle valve side. Resistance between terminal No. 1 and No. 2. OK: 0.3 - 80 kΩ (at 20 °C) Q: Is the check result normal? YES: Go to Step 3 . NO: Replace throttle body assembly.
| STEP 3. Connector check: C-138 engine-A/T-ECU connector
| Q: Is the check result normal? YES: Go to Step 4 . NO: Repair.
| STEP 4. Check harness between B-33 (terminal No. 1) electronically controlled throttle valve connector and C-138 (terminal No. 133) engine-A/T-ECU connector.
| Check output line for short circuit and damage. Q: Is the check result normal? YES: Go to Step 5 . NO: Repair.
| STEP 5. Check harness between B-33 (terminal No. 2) electronically controlled throttle valve connector and C-138 (terminal No. 141) engine-A/T-ECU connector.
| Check output line for short circuit and damage. Q: Is the check result normal? YES: Go to Step 6 . NO: Repair.
| STEP 6. Check the trouble symptoms. Q: Is the check result normal? YES: Replace engine-A/T-ECU. NO: Intermittent malfunction (Refer to GROUP 00 - How to Use Troubleshooting/Inspection Service Points ).
