Parts for your 2010 Ford Falcon-Crank angle sensor

2010 Ford Falcon crank-angle-sensor: purpose, reliability and service tips

Based on the Ford FG Falcon Workshop Manual (Engine Control), Ford Microcat parts catalogue, and common industry references like Autodata and Bosch engine management guides, the 2010 Ford Falcon is fitted with a crank-angle-sensor, more commonly called a crankshaft position sensor (CKP). It’s standard across the Barra 4.0 inline-six (petrol and LPG) and the 5.4 V8 variants.

On this Falcon, the crank-angle-sensor sits at the front of the engine near the timing cover, reading a toothed wheel on the crank. Its job is to tell the ECU exactly where the crank is and how fast it’s spinning. That live timing reference lets the ECU control ignition timing, injector pulse, variable cam timing and even the tachometer behaviour. If the CAS/CKP drops out, the engine generally won’t start, if it goes intermittent, expect rough running, random stalls or a sudden cut like someone flicked the key.

There’s no scheduled replacement interval for the sensor, it’s a “replace on condition” item. As the kilometres add up, heat, oil vapour and vibration can fatigue the sensor or its wiring. During routine servicing it’s worth a quick look under the bonnet: check the harness and connector at the front of the engine for chafing, hardening or oil saturation. A light clean of the connector and a dab of dielectric grease can help keep moisture at bay. If the harmonic balancer has been off, make sure the trigger wheel is clean and undamaged.

Typical clues that the Falcon’s crank-angle-sensor is playing up include:

• Long crank/no start when hot, then starts fine when cool
• Sudden stall at idle or cruise, no fault until it cools again
• Misfire with erratic tacho and stored P0335/P0339 codes

If any of those show up, a scan with live data (crank signal, RPM during crank) saves guesswork. When replacing, go for genuine Ford/Motorcraft or a quality OE-equivalent sensor, and inspect the loom back to the ECU for brittle insulation—especially on higher-mileage utes and taxis. On LPG E-Gas models, the advice stays the same, the ECU still relies on the same precise crank signal. Fitment is straightforward for a trained tech and doesn’t require timing re-learn on most FG ECUs, but clearing codes and checking for updated calibration is smart practice.

Does a 2010 Ford Falcon have a crank-angle-sensor?

Yes. Ford’s service literature for the FG platform specifies a crankshaft position sensor (often called a crank-angle-sensor) for all 2010 Falcon engines. It’s a primary timing input the ECU can’t run without.

Where is the crank-angle-sensor on a 2010 Falcon?

It’s mounted at the front of the engine by the timing cover, reading a toothed wheel on the crankshaft behind the harmonic balancer. Don’t mix it up with the cam sensors higher up on the head.

How do you know it’s failing on a 2010 Falcon?

Common signs are hot no-starts, sudden stalling, erratic tacho, and fault codes like P0335/P0339. A technician will confirm by checking live RPM during crank and inspecting the wiring and connector for heat or oil damage.
