Parts for your 2008 Ford Falcon-Crank angle sensor

2008 Ford Falcon crank-angle-sensor — what it does and when to replace it

Yes, the 2008 Ford Falcon does use a crank-angle sensor (more commonly called a crankshaft position or CKP sensor). This applies to both the Barra 4.0-litre inline six and the 5.4-litre Boss V8. Technical documentation including Ford’s FG Falcon Workshop Manual (Engine – Electronic Engine Controls, 2008), Max Ellery’s Ford Falcon FG Series 2008–2014 Repair Manual, and Autodata component-location guides all identify the CKP sensor as a key engine-management input on these models. On the Barra I6 it reads the flywheel/flexplate at the bellhousing, on the Boss V8 it reads a trigger wheel at the front of the crank.

On a 2008 Falcon, the crank-angle sensor tells the ECU exactly where the crankshaft sits in its rotation and how fast it’s spinning. That timing signal is the backbone for spark and fuel injection, and it also helps the ECU coordinate variable cam timing on the Barra. If the sensor signal goes missing or glitchy, the engine won’t know when to fire—leading to hard starting, misfires, stalling when hot, or a no-start with the tacho dead and a P0335-style fault code stored.

It’s not a scheduled service item, but it definitely benefits from a bit of attention during regular servicing. A quick visual once-over for damaged wiring, loose connectors, or oil contamination is worthwhile, especially on higher‑kilometre utes and sedans. Keeping nearby oil leaks in check helps too, as oil can soften the harness and attract grime.

Replacement is straightforward for most home spannering types. On the 4.0 I6, access is usually from underneath near the bellhousing, it’s a single retaining bolt and an O‑ringed sensor body. On the 5.4 V8, it’s mounted near the crank pulley at the front of the engine. Disconnect the battery, unplug the connector, swap the sensor, lightly lube the O‑ring, and torque the bolt to spec. Clear codes and, if prompted by a scan tool, perform a CKP/CMP relearn so the ECU synchronises cleanly. Expect 0.5–1.0 hours labour. Use a quality OE‑equivalent sensor—going cheap can mean intermittent heat soak issues that are a pain to chase.

Owners typically see failures crop up with age, heat, or after gearbox work on the I6 (where the harness can be disturbed). If the Falcon is cranking but refusing to fire, the CKP is one of the first checks—because without its signal, there’s simply no go.

• Common symptoms: long crank/no start, random stalling, misfire at hot idle, dead tacho during crank, codes like P0335.
• Typical cost: AUD/NZD $60–$180 for the part, modest labour at an independent workshop.

Popular questions

Where is the crank-angle sensor on a 2008 Ford Falcon?
On the 4.0-litre Barra I6 it’s mounted at the bellhousing, reading the flexplate/flywheel teeth—access is usually from underneath near the starter area. On the 5.4-litre Boss V8 it sits at the front of the engine by the crank pulley, reading a trigger wheel behind the harmonic balancer.

What are the tell-tale signs the crank-angle sensor is failing?
Hard starting or a complete no-start when hot, sudden stalling at traffic lights, intermittent misfires, and a dead or jumpy tacho while cranking. The ECU often logs P0335/P0336-type codes. Heat soak after a short stop is classic—starts cold, refuses when hot, then starts again after cooling.

Can the sensor be cleaned, or should it just be replaced?
Light cleaning of debris on the tip and ensuring the connector is clean and tight can help if the issue is minor contamination. However, once the internal Hall/inductive element degrades, replacement is the proper fix. If the loom is brittle or oil-soaked, repair or replace the pigtail at the same time.
