Parts for your 2010 Ford Falcon-Camshaft sensor

2010 Ford Falcon camshaft sensor – what it does and how to look after it

Yes, the 2010 Ford Falcon uses a camshaft position sensor, and it’s a key part of the engine management on all FG variants (4.0L I6, LPG/E-Gas, XR6 Turbo and the V8s). This is confirmed across technical sources including the Ford FG Falcon Workshop Manual (Engine Management, Section 303), Autodata’s AU/NZ vehicle data, and major OE supplier catalogues for the FG platform. Those sources specify a dedicated camshaft position (CMP) input for sequential injection timing and variable cam timing control.

On the FG Falcon, the camshaft sensor lets the PCM know exactly where the cam is in its rotation so it can sync fuel injection and manage variable cam timing. That precision helps the Barra I6 and the V8 deliver smooth idle, decent fuel economy and strong throttle response. The I6 typically has one sensor mounted at the front of the cylinder head near the timing cover, V8s use a sensor on each bank.

When the cam sensor goes out of whack, the car can act like it’s had a late night. Typical signs include:

• Hard starting or long cranking, especially when hot
• Rough idle, flat spots or random stalling
• Sluggish performance and higher fuel use
• Check Engine light with codes like P0340 or P0341
• Limp-home behaviour if the PCM loses sync

There’s no scheduled replacement interval, but it’s smart to check the sensor and its plug at service time. Under the bonnet, look for oil wicking into the connector, brittle wiring or harness chafe along the front of the rocker cover. Because the sensor reads a clean magnetic signal, old oil and metal debris in the area can cause noise—keeping up with oil changes helps. If faults appear, use a scan tool to confirm sync loss, and if available, an oscilloscope to view the cam signal alongside crank.

Replacement is straightforward with basic tools: disconnect the battery, unplug the sensor, remove its retaining fastener, swap the sensor, and refit the seal if separate. Reconnect, clear codes, and take a short drive so the PCM can relearn. Programming is generally not required on the FG, but poor wiring or a cheap, noisy aftermarket sensor can bring the fault back. Tighten fasteners to the workshop manual spec and always route the loom so it doesn’t rub. Quality parts and tidy wiring will keep the Falcon happy for many more kilometres.

Popular questions about 2010 Ford Falcon camshaft sensors

Where is the camshaft sensor on a 2010 Falcon?
On the 4.0L inline‑six it’s typically mounted at the front of the cylinder head near the timing cover. On the V8 models, there’s one sensor per bank near the front of the engine. Access is under the bonnet with the engine cover off, and usually only a small spanner or socket is needed.

Does a new camshaft sensor need programming?
On FG Falcons, a new cam sensor usually doesn’t need programming. After installation, clear any fault codes and complete a short drive so the PCM can resynchronise. If a code returns immediately, check the wiring, connector condition and sensor brand/quality.

Can driving with a bad cam sensor cause damage?
It won’t normally cause mechanical damage by itself, but it can lead to hard starts, poor running and misfires. Prolonged misfiring can stress the catalytic converter, so it’s best to fix cam sensor issues promptly.
