The P210C: Throttle Actuator ‘B’ Control Motor Circuit Low fault code indicates that the voltage in the throttle actuator ‘B’ control motor circuit is lower than expected. This can affect throttle control, leading to poor engine performance. The issue could be caused by low voltage in the circuit, a faulty throttle actuator motor, or wiring problems.
P210C – Quick Overview
| Code | Information |
|---|---|
| Meaning | P210C: Throttle Actuator ‘B’ Control Motor Circuit Low |
| Is it serious? | Yes, low voltage can result in improper throttle control, affecting engine performance and drivability. |
| Possible causes | – Low 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 |
P210C Meaning
The P210C fault code indicates that the throttle actuator ‘B’ control motor is receiving lower-than-expected voltage, which can prevent the throttle actuator from properly controlling the throttle valve. This can result in reduced engine performance and throttle response. The issue could stem from wiring problems or a failing throttle actuator motor.
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 further context about the low 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 low voltage. | Multimeter |
| Test the Throttle Actuator Motor | Use a diagnostic tool to test the throttle actuator motor’s functionality and ensure it is operating within the correct voltage range. | Diagnostic Tool, Multimeter |
| Inspect Wiring for Issues | Visually inspect the wiring for damage, loose connections, or corrosion that could cause a low voltage condition. Test for continuity if necessary. | Flashlight, Multimeter |
| Repair or Replace Faulty Components | If a faulty throttle actuator motor or damaged wiring is identified, repair or replace the components to restore normal voltage and function. | 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 ensure the issue is resolved. | OBD-II Scanner, Vehicle Manual |
| Recheck for Codes | After the test drive, rescan the vehicle to ensure the P210C code does not return. | OBD-II Scanner |
