Parts for your 2012 Ford Falcon-Crank angle sensor

2012 Ford Falcon crank-angle-sensor: what it does and how to look after it

Yes, the 2012 Ford Falcon uses a crank-angle-sensor (also called a crankshaft position sensor or CKP). Technical references including the Ford FG MkII Falcon Workshop Manual (2011–2014) for both the 4.0L Barra I6 and the 2.0L EcoBoost engines specify a CKP sensor for engine timing and synchronisation. Common AU/NZ service data sets (e.g., Autodata and trade catalogues) list a CKP for this model, and Ford diagnostic procedures reference DTCs P0335/P0336 for CKP faults.

On a 2012 Falcon, the crank-angle-sensor tracks the exact position and speed of the crankshaft so the ECU can fire the injectors and coils at the right moment. No accurate crank signal means no start, rough running, or the sort of intermittent stalling that makes anyone grumpy on a Monday morning.

Location depends on engine. The 4.0L Barra mounts the sensor near the bellhousing, reading a reluctor on the crank. The 2.0L EcoBoost places it at the front of the block by the crank pulley. Either way, it’s a sealed Hall-effect sensor designed to be fit-and-forget—there’s no scheduled replacement interval—but it can be taken out by heat, vibration, or oil contamination.

Typical symptoms include:

• Hard start or no start, long crank, or sudden stall
• Tacho dropouts, misfire under load, or limp-home behaviour
• Fault codes like P0335/P0336

Service tips for the Falcon crowd:

• Inspect the sensor connector and loom routing—brittle insulation near the exhaust is common. Repair damaged wiring before fitting a new sensor.
• If there’s oil seepage, fix the leak so it doesn’t contaminate the sensor face.
• Replacement is straightforward: disconnect the battery, access the sensor, remove the retaining bolt, twist the old sensor out, lightly lube the new O-ring, seat fully, and refit the bolt to workshop-manual torque. Route the harness away from heat and moving parts.
• Clear codes and perform an idle/crank relearn if prompted by your scan tool. Many Falcons relearn automatically after a few drive cycles.

Use quality OE-equivalent parts, bargain-bin sensors can introduce signal noise that mimics a wiring fault. If the car still plays up after replacement, scope the CKP and cam signals together—on these Falcons, poor synchronisation from a stretched timing chain (rare on Barra, more a general note) or incorrect air gap due to debris can look like a bad sensor.

FAQs

Where is the crank-angle-sensor on a 2012 Ford Falcon?
On the 4.0L Barra I6, it sits near the transmission bellhousing reading the crank trigger wheel. On the 2.0L EcoBoost, it’s typically at the front of the engine by the crank pulley. Access varies, the Barra often needs work from underneath, while the EcoBoost is approached from the front.

What are the common signs it’s failing?
No start, random stalling, long cranking, tachometer flickers, and engine light with P0335/P0336. Heat-soak no-start after a hot shut-down is a classic. Always check the wiring and connector before condemning the sensor.

Do I need a relearn after replacement?
Many Falcons will relearn crank correlation automatically after a few starts and a short drive. If a code persists or idle is unstable, use a compatible scan tool to run a crank/cam correlation or KAM reset and then complete an idle relearn drive cycle.
