P1220 — Throttle Control fault (traction control system)

System: Powertrain  |  Type: Manufacturer-Specific  |  Make: Ford

About P1220

P1220 is a manufacturer-specific powertrain diagnostic trouble code recorded for Ford vehicles. It belongs to the P-prefix family of codes, which covers engine, transmission, emissions, or fuel-system faults.

Scanning & clearing: A generic OBD-II scan tool will usually read and clear powertrain (P) codes. For live data, freeze-frame capture, and bi-directional tests you may need a more capable scan tool that supports the vehicle's ECM protocol.

P1220 is a manufacturer-specific code. The same code string on a different make may have a different meaning. Always confirm the code's definition against the vehicle's service information for the specific make and model under test.

Code Information

On vehicles where the traction control system reduces engine power by acting on the throttle, the Powertrain Control Module (PCM) manages a throttle control function that the traction control relies on to close the throttle and cut torque during wheel slip. DTC P1220 is set when the PCM detects a fault in this throttle control system, such as the throttle not responding correctly to commands, disagreement between the throttle position sensors, or a loss of proper control of the throttle actuator. On systems fitted with a secondary or series throttle plate for traction control, the fault can li...
