Parts for your 2006 Ford Fiesta-Crank angle sensor

2006 Ford Fiesta crank-angle sensor: what it does and how to look after it

Yes, the 2006 Ford Fiesta is fitted with a crank-angle sensor (Ford calls it the Crankshaft Position or CKP sensor). Technical sources that document this include the Ford Workshop Manual (TIS/ETIS) for Fiesta 2002–2008, Engine Management sections 303-14A/303-14B, which show the CKP sensor location and service steps, the Haynes Ford Fiesta Petrol & Diesel 2002–2008 manual, which details CKP testing and removal, and Ford’s Microcat parts catalogue, which lists a CKP sensor across the 1.25/1.4/1.6 Duratec petrol and 1.4 TDCi diesel variants for MY2006.

On a 2006 Fiesta, the crank-angle sensor tracks crankshaft speed and exact position so the engine computer can trigger spark and fuel right on cue. Without a clean CKP signal, the car can crank but won’t fire, or it’ll run rough as guts. It works off a toothed wheel (reluctor) on the crank or flywheel, and on most Fiesta engines of this year it’s mounted at the gearbox bellhousing reading the flywheel teeth. Some variants place it near the crank pulley—either way, it’s a small magnetic sensor with a single retaining bolt and a plug.

This part isn’t a scheduled service item, but it’s smart to give it a look during major services. Oil leaks, coolant weeps, or road grime can creep into the connector and cause intermittent no-starts once hot. If there’s a check-engine light with codes like P0335–P0339, or if the tacho drops to zero right as the engine cuts out, the CKP is a prime suspect.

Replacement is straightforward for a competent DIYer or mechanic:

• Disconnect the battery negative and get safe access (often from underneath after removing the splash shield).
• Unplug the sensor, remove the single bolt, and gently twist the sensor free. Check the O-ring and the reluctor for damage.
• Lightly oil the new O-ring, install the sensor, route the loom away from heat and moving parts, and tighten to workshop-spec torque.
• Clear any fault codes and confirm a quick, clean start with stable idle.

Tips for longer life: keep an eye out for oil leaks at the rear main area, avoid pressure-washing electrical connectors, and fix chafed wiring early. Stick with reputable brands (OE-equivalent) as cheap sensors can play up when hot. There’s no routine cleaning needed, but if you’ve had a clutch or rear main done, it’s worth inspecting the CKP alignment and connector while you’re in there.

Popular questions

Does a 2006 Ford Fiesta have a crank-angle sensor and where is it?
Yes. Every 2006 Fiesta engine option uses a CKP sensor. It’s typically mounted on the gearbox bellhousing reading the flywheel teeth, some petrol variants place it near the crank pulley. Look for a small sensor with one bolt and a two- or three-pin plug.

What are the symptoms of a failing crank-angle sensor on a Fiesta?
Common signs include long cranking or no-start when hot, sudden stalling, misfires, rough idle, and the rev counter dropping to zero as it cuts. The ECU often logs P0335–P0339 codes. Intermittent faults can be heat-related and show up after a short stop on a warm day.

How much does replacement usually cost?
In Australia or NZ, expect a quality CKP sensor to run roughly the low hundreds in parts, with about 0.5–1.0 hours labour depending on access. Pricing varies by engine variant and brand—OE-equivalent parts are recommended for reliability.
