Parts for your 2006 Ford Mondeo-Crank angle sensor

2006 Ford Mondeo crank angle sensor (crankshaft position sensor)

Based on Ford TIS workshop documentation for the 2006 Mondeo, the Haynes Mondeo 2001–2007 manual (petrol and diesel), and Autodata service information, this model is fitted with a crankshaft position sensor—commonly referred to as a crank angle sensor (CKP). Ford parts catalogues for the Mk3 Mondeo list the CKP across Duratec petrol and Duratorq TDCi diesel engines, confirming it’s a core engine management component rather than an optional extra.

The crank angle sensor tells the powertrain control module exactly where the crankshaft is and how fast it’s spinning. That live signal lets the PCM fire the injectors and spark at the right moment, sync with the cam sensor, manage starting, and keep the idle tidy. On TDCi diesels, it’s critical for precise high‑pressure injection timing. If the CKP signal drops out, the Mondeo can be hard to start, stumble, or stall—and in some cases won’t start at all.

While the CKP isn’t a scheduled replacement item, it should get a look during servicing. A quick visual check of the wiring loom and connector for oil contamination, heat damage, or chafing goes a long way. If the engine’s throwing codes like P0335–P0339, cranks a long time before firing, the tacho sits dead while cranking, or there’s random cut‑outs, the sensor or its wiring is high on the suspect list.

• Testing: Use a scan tool to confirm RPM during cranking, no RPM usually points at the CKP or its circuit. An oscilloscope trace is gold for spotting dropouts or noise.
• Replacement: Disconnect the battery earth, access the sensor (on most Duratec petrols it’s at the bellhousing, on many Duratorq diesels it’s near the flywheel housing), remove the retaining bolt, clean the mounting face, fit a new O‑ring if applicable, and torque to Ford spec. Clear DTCs and perform an idle/KAM relearn if required.
• Fitment tips: Use quality OE‑equivalent parts, keep the sensor tip clean of metallic debris, and route the harness away from sharp edges and hot spots. The air gap is fixed by the mount—there’s no adjustment.

For everyday servicing of a 2006 Ford Mondeo crank angle sensor, the best approach is “inspect, test, replace on condition”. That keeps the Mondeo starting first pop and running sweet across Aussie and Kiwi kilometres.

FAQs

Where is the crank angle sensor on a 2006 Ford Mondeo?
On most Duratec petrol engines (1.8/2.0/2.5), the CKP sits at the gearbox bellhousing area reading the flywheel/reluctor. On many Duratorq TDCi diesels, it’s mounted at the flywheel housing or low on the block near the crank. Access is from underneath, removing undertrays makes life easier.

What symptoms and fault codes point to a failing CKP?
Hard starting (especially hot), intermittent stalling, rough idle, misfires under load, or a dead tacho while cranking are common. The PCM may log P0335, P0336, P0337, P0338, or P0339. Always check wiring and connectors before condemning the sensor.

Does the CKP need programming after replacement?
The sensor itself doesn’t need coding. After replacement, clear fault codes and perform a KAM/idle relearn if the PCM has lost its adaptive trims. On TDCi models, injector coding is separate and unaffected by CKP replacement.
