P2101 on Ford
Throttle Actuator "A" Control Motor Circuit Range/Performance
P2101 on Ford vehicles indicates throttle actuator "a" control motor circuit range/performance. Au7o has documented this code across 2 Ford models — most commonly on Transit, Transit Connect. This powertrain code means the engine computer commanded the electronic throttle actuator motor to a certain position but the motor did not respond within the expected range. Modern engines use a drive-by-wire throttle, where a motor opens and closes the throttle plate based on signals from the computer rather than a cable. When the actual throttle position disagrees with the commanded position, the computer sets this code, often forcing the vehicle into a reduced-power 'limp' mode to protect the engine. This can cause poor acceleration or stalling and should be addressed promptly. Typical repair costs on Ford range from $140 to $900, depending on the specific model and root cause.
Common Causes of P2101
- •Faulty throttle actuator control motor (throttle body)
- •Dirty or carbon-fouled throttle plate causing binding
- •Wiring or connector problems in the throttle actuator circuit
- •Failed throttle position sensor inside the throttle body
- •Poor electrical connection or corroded terminals
- •Faulty engine control module (less common)
P2101 on Ford by Model
Ford Transit(1 issue)
- 3.7L Ti-VCT Throttle Body Failure / Electronic Throttle Control (ETC) Limp Mode2015-2019
Owners report sudden loss of power with a wrench light and reduced throttle response, often while cruising or accelerating. NHTSA complaints and Ford service information describe electronic throttle body internal faults (TPS/actuator) that can trigger ETC failsafe and limp mode on 3.7L Ti-VCT Transits. The condition may be intermittent at first and then become frequent, especially with heat/soak and higher mileage.
Ford Transit Connect(1 issue)
- Throttle Body/ETC Fault Causing Limp Mode (Reduced Engine Power)2014-2021
Owners report sudden reduced power, poor throttle response, and limp-home behavior due to electronic throttle body contamination/wear or throttle actuator control faults. The issue can be intermittent and may clear after a key cycle, then recur, which is a common pattern in NHTSA complaints and owner reports. It often sets throttle/ETC-related DTCs and can be triggered by carbon buildup or failing throttle position sensing.

What does P2101 mean on Ford?▼
P2101 stands for "Throttle Actuator "A" Control Motor Circuit Range/Performance." This powertrain code means the engine computer commanded the electronic throttle actuator motor to a certain position but the motor did not respond within the expected range.

When the actual throttle position disagrees with the commanded position, the computer sets this code, often forcing the vehicle into a reduced-power 'limp' mode to protect the engine. This can cause poor acceleration or stalling and should be addressed promptly. On Ford specifically, this code is documented across 2 models.
What causes P2101 on Ford vehicles?▼
Common causes on Ford: Faulty throttle actuator control motor (throttle body), Dirty or carbon-fouled throttle plate causing binding, Wiring or connector problems in the throttle actuator circuit, Failed throttle position sensor inside the throttle body, Poor electrical connection or corroded terminals.
