Fix P210D: STEP-BY-STEP diagnostic GUIDE!

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

CodeInformation
MeaningP210D: 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

ActionDescriptionTools Needed
Check for Other CodesUse 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 CircuitUse 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 MotorUse 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 IssuesVisually 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 ComponentsIf 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 DriveAfter 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 CodesAfter the test drive, rescan the vehicle to ensure the P210D code does not return.OBD-II Scanner
