The P210D: Throttle Actuator ‘B’ Control Motor Circuit High fault code indicates that the voltage in the throttle actuator ‘B’ control motor circuit is higher than expected. This can interfere with proper throttle control, affecting engine performance and throttle response. Common causes include high voltage in the circuit, a faulty throttle actuator motor, or wiring issues.
P210D – Quick Overview
| Code | Information |
|---|---|
| Meaning | P210D: Throttle Actuator ‘B’ Control Motor Circuit High |
| Is it serious? | Yes, high voltage can cause improper throttle control, affecting drivability and engine performance. |
| Possible causes | – High voltage in the throttle actuator ‘B’ control motor circuit – Faulty throttle actuator motor – Wiring issues |
| How to diagnose? | – Measure voltage in the throttle actuator ‘B’ control motor circuit – Test the throttle actuator motor – Inspect wiring for issues |
P210D Meaning
The P210D fault code means that the voltage in the throttle actuator ‘B’ control motor circuit is higher than the normal operating range. This can lead to poor throttle control, improper throttle response, and potential drivability issues. The problem may be caused by faulty wiring, a malfunctioning throttle actuator motor, or issues in the electrical circuit.
Step-by-step diagnostic guide
| Action | Description | Tools Needed |
|---|---|---|
| Check for Other Codes | Use an OBD-II scanner to check for additional related codes that may provide more details about the high voltage issue in the throttle actuator circuit. | OBD-II Scanner |
| Measure Voltage in the Throttle Actuator ‘B’ Control Motor Circuit | Use a multimeter to measure the voltage in the throttle actuator control motor circuit and compare it to the manufacturer’s specifications to identify high voltage. | Multimeter |
| Test the Throttle Actuator Motor | Use a diagnostic tool to test the throttle actuator motor to ensure it is operating within the correct voltage range and not causing the high voltage issue. | Diagnostic Tool, Multimeter |
| Inspect Wiring for Issues | Visually inspect the wiring for signs of damage, loose connections, or corrosion that could be causing excessive voltage. Test for continuity and proper voltage if necessary. | Flashlight, Multimeter |
| Repair or Replace Faulty Components | If the throttle actuator motor or wiring is faulty, repair or replace the necessary components to restore proper voltage levels and throttle control. | Replacement Parts, Tools |
| Clear the Code and Test Drive | After completing repairs, clear the fault code using an OBD-II scanner and take the vehicle for a test drive to confirm that the issue is resolved. | OBD-II Scanner, Vehicle Manual |
| Recheck for Codes | After the test drive, rescan the vehicle to ensure the P210D code does not return. | OBD-II Scanner |
