Parts for your 2011 Ford Transit-Throttle position sensors

2011 Ford Transit throttle position sensor: what it does, and when to service or replace it

Yes, a throttle position sensor (TPS) is used on the 2011 Ford Transit. On petrol models the TPS is part of the throttle body. On the common 2.2L/2.4L Duratorq TDCi diesels (VM series in AU/NZ), there’s an electronically controlled intake throttle flap (also called the air shut-off valve) with an integrated position sensor. This is confirmed in Ford ETIS/Workshop Manual VM Transit 2006–2013, section 303‑14B Fuel Charging and Controls, and corresponding Ford wiring diagrams listing TPS circuits and DTCs P0120–P0123. Bosch EDC16/EDC17 system notes and the Haynes Transit Diesel 2006–2013 manual also describe the throttle flap with position feedback for EGR and smooth shutdown.

On this Transit, the TPS tells the PCM exactly how far the throttle plate is open. In the diesels it isn’t about engine load like a petrol—they use the flap to help EGR flow, stabilise idle, improve emissions, and give a gentle engine stop. If the sensor goes skew-whiff, expect rough idle, hesitation, limp mode, surging, harsh shutdown, higher fuel use, or the MIL on. Common codes include P0120–P0123 for TPS range/performance, and sometimes throttle actuator codes like P2106, P2110 or P2111.

Servicing is straightforward. The TPS is sealed into the throttle body on most variants, so you replace the throttle body assembly if the sensor is faulty. Under the bonnet, inspect the connector and loom for chafe, oil wicking and green crusties. Use a scan tool to check live data—throttle command vs. throttle position should track smoothly with no dropouts. If numbers jump or stick, it’s likely time for a new unit.

During routine servicing (every 20,000–30,000 km for many AU/NZ schedules), it pays to:

• Check for stored DTCs even if the light’s off.
• Visually inspect and gently clean the throttle bore if sooted. Avoid harsh sprays on the motor/sensor, use throttle-safe cleaner and a lint-free cloth.
• Confirm good battery voltage and grounds—low volts cause false TPS faults.
• After replacement or a battery disconnect, perform a throttle/idle relearn with a capable scan tool, many workshops use Ford IDS/FDRS or equivalent.

Replacement is typically a 0.5–1.0 hour job on the diesel, a bit more if access is tight. Use quality parts (many OE units are Bosch or Pierburg), new gasket if applicable, and torque the fasteners correctly. A smooth idle and snappy throttle response afterwards is the giveaway that the Transit’s TPS and throttle body are playing nicely again.

FAQs

Does a 2011 Transit diesel actually have a throttle position sensor?
Yes. The Duratorq TDCi uses an electronic intake throttle flap with an integrated position sensor. It’s different from the accelerator pedal sensor—the TPS reports the flap angle to the PCM for EGR control, idle quality and clean shutdown.

What fault codes point to a TPS issue on a 2011 Transit?
Look for P0120, P0121, P0122 and P0123 for TPS circuit or range faults. You may also see throttle actuator related codes like P2106, P2110 or P2111 when the PCM limits power after it detects a mismatch between commanded and actual throttle position.

Can you clean or recalibrate the TPS, or does it need replacing?
The sensor is sealed into the throttle body, so you don’t service it separately. Lightly clean the throttle bore if sooted, fix wiring issues, then run a throttle/idle relearn with a proper scan tool. If the position signal is still erratic, replace the throttle body assembly.
