Throttle Actuator B Control Motor Circuit/Open

Where it lives

For P210A, the circuit described runs through the actuator. The description of P210A reports the actuator as open.

Check these first

• An open in the throttle actuator B control motor circuit
• A backed out pin at the throttle actuator B connector
• A failed throttle actuator B control motor
• Low battery voltage

What to do next

1. Command the throttle actuator B on a scan tool
2. Test the actuator B control motor circuit for an open
3. Check the actuator B connector pins
4. Check battery voltage and charging system output
5. Replace the throttle actuator B if the circuit tests good
6. Clear the code and retest
