Throttle Actuator B Control Motor Circuit Low

Where it lives

For P210C, the circuit described runs through the actuator. The description of P210C reports a fault at the actuator.

Check these first

• A short to ground on the throttle actuator B control motor wire
• An open in the actuator B control motor power feed
• A failed throttle actuator B control motor
• Corrosion at the actuator B connector

What to do next

1. Read the throttle actuator B control motor circuit on a scan tool
2. Test the actuator B control motor wire for a short to ground
3. Check the actuator B control motor power feed for an open
4. Measure actuator B control motor resistance
5. Replace the throttle actuator B if it tests out of range
6. Clear the code and retest
