Parts for your 2013 Ford Transit-Crank angle sensor

2013 Ford Transit crank-angle-sensor (crankshaft position sensor)

Based on technical references including the Ford TIS workshop information for the 2013 Transit (Duratorq TDCi), the Haynes Ford Transit Diesel 2006–2013 manual, and Autodata/Bosch ESI[tronic] service data, the 2013 Ford Transit is fitted with a crankshaft position sensor—often called a crank angle sensor (CAS). It’s a primary engine management input and absolutely relevant to diagnostics and servicing on this model.

The crank angle sensor on a 2013 Ford Transit does the heavy lifting for engine timing. It reads a toothed wheel on the crank (or flywheel), sending a precise engine speed and position signal to the ECU. That lets the ECU fire injectors and manage timing bang on, which means easy starts, smooth idle, proper power, and clean emissions. Without a clean CAS signal, the Transit can crank and not start, stumble, or drop into limp mode.

This sensor isn’t a scheduled service item, but it deserves a bit of attention during routine servicing. A quick visual under the bonnet (and often from under the van near the bellhousing) to check the sensor body, connector, and loom for chafe, oil contamination, or broken clips goes a long way. Oil leaks, road grime, or metal filings can muck up the magnetic tip and distort the signal, so keeping the area clean and fixing any leaks early is smart.

If replacement is needed, pick an OE-quality sensor. Disconnect the battery, safely raise the vehicle if access is from underneath, and mind hot exhaust components. The CAS is usually held with a single small fastener and an O-ring seal—lightly oil the new O-ring, seat the sensor square, and don’t over-tighten. Route the harness as per factory path to avoid heat and abrasion. After fitting, clear fault codes, check live data for a stable engine speed reading during crank, and take a short road test. Most Transits won’t need programming after a CAS swap, but a scan-tool KAM reset and code clear is good practice.

Common signs it’s time to test the CAS include extended cranking, random stalling, erratic tachometer behaviour, poor fuel economy, and a check engine light—often with codes like P0335–P0339. Before condemning the sensor, verify power, ground, and signal wiring integrity, a loom fault is a frequent culprit on working vans that clock serious kilometres.

• Purpose: Provides precise engine speed/position so the ECU can time injection and ignition.
• Service tip: Inspect wiring and keep the sensor area clean, fix oil leaks early.
• Replacement: Use quality parts, fit square with a fresh O-ring, clear codes, verify live data.
• Diagnostics: Look for DTCs P0335–P0339 and check loom/connector before replacing.

Does a failing crank angle sensor stop a 2013 Transit from starting?

It can. With no or a noisy signal, the ECU won’t trigger injection properly, so you’ll get long cranks, a no-start, or sudden stalling. Always scan for codes and confirm the sensor’s power/ground and signal before swapping parts.

Is programming needed after replacing the crank angle sensor?

On most 2013 Transits, no special programming is required. Clear fault codes, perform a KAM reset if available on your scan tool, and verify stable RPM in live data. If problems persist, recheck wiring and sensor fitment.

Where is the crank angle sensor on a 2013 Transit?

Depending on engine and drive layout, it’s typically mounted near the bellhousing reading the flywheel tone ring, or at the front of the engine reading the crank pulley. Access is often easier from underneath, use stands and work safely.
