Parts for your 2008 Ford Falcon-Camshaft sensor

2008 Ford Falcon camshaft sensor — fitment, purpose, and service tips

For the 2008 Ford Falcon, a camshaft position (CMP) sensor is absolutely fitted and relevant. Technical references including the Ford Falcon BF MkII/III and early FG Workshop Manuals (Engine Management, Section 303), Autodata engine management wiring diagrams, and industry catalogues for the Barra 4.0 DOHC I6 and Boss 5.4 V8 confirm the presence of a CMP sensor. On Barra-powered Falcons (including LPG and Turbo), the CMP sensor is mounted at the front of the cylinder head near the timing cover, Boss V8 models use cam sensors at the front of each head to support variable cam timing. The PCM relies on this sensor for synchronised sequential injection, ignition timing, and cam phasing control, with common DTCs such as P0340/P0341 flagging CMP faults.

What does it do day-to-day? The camshaft sensor tells the Falcon’s PCM exactly which stroke each cylinder is on, so it can fire injectors and coils at the right moment and manage the variable cam timing system. It also improves cold starts, trims fuel economy, and helps the engine run clean and smooth. If the signal’s missing or noisy, the car may crank longer, run rough, or fall back to a default strategy that dulls performance.

• Typical symptoms of a tired or faulty CMP sensor:
  • Hard starting, long crank, or stalling after start
  • Rough idle, hesitation, or flat spots
  • Poor fuel economy and reduced power, sometimes limp mode
  • Check Engine light with codes like P0340/P0341

Replacement and care are straightforward. The sensor itself isn’t a routine service item, but clean engine oil is vital because the Barra’s variable cam timing relies on oil pressure and flow, dirty oil can trigger cam correlation faults that look like a bad sensor. Before replacing, inspect the connector, harness routing, and any oil leaks around the timing cover that might contaminate the plug.

When fitting a new CMP sensor, disconnect the battery, unplug the connector, remove the retaining fastener, and swap the sensor, lightly oiling any O-ring. Refit to the workshop-specified torque, reconnect, clear codes, and check live data for stable cam and crank sync. Use quality OE-equivalent parts and avoid forcing the connector latch. If faults persist, verify crank sensor health and mechanical timing—especially on high-kilometre Barra engines where chain stretch or a sticky phaser can skew the cam signal.

There’s no scheduled interval to replace the camshaft sensor on a 2008 Falcon, treat it as a diagnose-and-replace item, and keep up with regular oil and filter changes to keep the timing system happy.

Popular questions

Where is the camshaft sensor on a 2008 Ford Falcon?
On the Barra 4.0 inline six, it sits at the front of the cylinder head near the timing cover on the intake side. On Boss 5.4 V8 models, there’s a cam sensor at the front of each cylinder head. Access is usually from the top with basic hand tools.

Can you drive with a failing camshaft sensor?
Often, yes—but it’s not ideal. The PCM may revert to a backup strategy that hurts performance, economy, and emissions. If it’s intermittently cutting out, you may get stalling or hard restarts. It’s smarter to diagnose and fix it promptly to avoid getting stranded.

How do I tell if it’s the cam sensor or something else?
Scan for codes and check live data for cam/crank sync. Inspect the connector and wiring first. Because the Barra’s VCT depends on oil, poor oil quality, a sticky cam phaser, or stretched timing chain can mimic sensor faults. If in doubt, follow the workshop test plan before replacing parts.
