2010 Ford Transit crank-angle sensor: what it does, where it lives, and how to look after it

Based on technical references such as the Ford Workshop Manual for the 2006–2013 Transit range (Duratorq TDCi engines) and independent service data like Haynes (Transit Diesel 2006–2013) and Autodata, the 2010 Ford Transit is fitted with a crankshaft position sensor—often called a crank-angle sensor. These sources detail diagnostics for DTCs like P0335–P0339 and outline removal/refit procedures, confirming the part is absolutely relevant to this model.

On a 2010 Transit, the crank-angle sensor feeds the PCM exact crank speed and position so the engine knows when to inject fuel and fire. It works with a toothed wheel (often a 36-1 pattern) on the crank or flywheel. If it goes out to lunch, the van can be hard to start, misfire, stall, or not start at all. The dash may light up and the PCM will usually log a fault code.

It’s not a scheduled service item, but a little preventive care goes a long way. During regular servicing, it’s worth eyeballing the sensor area and loom. Look for oil contamination, rubbed-through insulation, loose connectors, or corrosion. If the tip is magnetic, metal filings can cling on—gentle cleaning with sensor-safe spray can help. Keep the harness clipped away from hot exhaust bits and sharp edges under the bonnet.

Replacement is straightforward for a competent DIYer, though workshop access makes life easier. Typical steps include disconnecting the battery, locating the sensor (commonly at the bellhousing reading the flywheel on many RWD Transits, some FWD variants place it near the crank pulley), removing the retaining bolt, and easing the sensor out. Lightly lubricate the new O-ring, seat the new unit squarely, and torque the bolt to spec per the workshop manual. No special programming is usually required—clear the codes and you’re away. If it still cranks but won’t fire, double-check the connector, wiring continuity, and that the sensor is fully seated with the correct air gap where applicable.

Common signs it’s time to sort the crank-angle sensor:

• Extended crank/no start, intermittent stalling, rough idle, or sudden loss of power
• Fault codes such as P0335–P0339
• Tachometer dropouts while cranking

Quality matters here—go genuine or a reputable aftermarket brand, and don’t ignore upstream issues like oil leaks that can soak the connector. A tidy sensor and loom can save a heap of hassle down the track for Kiwi and Aussie Transit owners alike.

FAQs

Where is the crank-angle sensor on a 2010 Ford Transit?
Most 2010 Transit Duratorq diesels have the sensor mounted at the gearbox bellhousing, reading the flywheel teeth, with access from underneath. Some front-wheel-drive variants place it near the front of the engine by the crank pulley. If unsure, check the engine variant label and consult the workshop manual for the exact spot.

What are the usual symptoms of a failing crank-angle sensor?
Hard starting or a no-start when hot, random stalling, rough running, and a dead or jumpy tacho during cranking are common. The PCM often stores codes like P0335–P0339. If those show up with starting or driveability grief, the sensor or its wiring is high on the suspect list.

Does the crank-angle sensor need regular servicing?
It isn’t a replace-by-interval item. However, during routine servicing it’s smart to check the connector, loom condition, and for oil or metal debris at the sensor tip. Keeping the area clean and the harness well-secured helps prevent intermittent faults.
