Throttle Actuator B Control System - Forced Limited RPM

Where it lives

For P210F, the description names the actuator as the part involved.

Check these first

• A throttle actuator B that fails to follow the commanded position
• A failed throttle position sensor
• A dirty or carboned throttle body
• A failed throttle actuator B control module

What to do next

1. Read the throttle position sensors on a scan tool
2. Command the throttle actuator B through its range
3. Clean the throttle body carbon
4. Test the throttle actuator B control circuit
5. Replace the throttle actuator B control module if travel is wrong
6. Clear the code and retest
