Parts for your 1997 Ford Falcon-Camshaft sensor

1997 Ford Falcon camshaft sensor: what’s fitted and how it’s looked after

Per the Ford EL Falcon Workshop Manual (1996–1998) and Autodata Service Information for the same era, the 1997 Falcon with the 4.0‑litre inline‑six uses a camshaft position/synchronisation sensor (CMP) mounted where the earlier distributor used to sit. The EL XR8 5.0‑litre V8 runs a conventional distributor and doesn’t use a separate CMP, the distributor’s Hall‑effect signal provides the timing reference. So a standalone camshaft sensor is relevant to the six‑cylinder EL, not the XR8.

On the six, the camshaft sensor tells the ECU which stroke cylinder one is on, letting it fire fuel injectors sequentially and tidy up cold starts, idle quality and emissions. Spark timing still relies primarily on the crank sensor with a wasted‑spark coil pack, but the cam signal makes the whole show smoother and a touch more efficient. If the sensor drops out, the engine usually reverts to batch‑fire injection, which means longer crank times and a slightly rougher idle, but it will generally still run.

It’s not a regular service item, yet it’s smart to give it some love during routine maintenance. The sensor lives in the old distributor hole on the side of the block and can get oily with age. Check the plug and wiring for brittle insulation, oil wicking into the connector, or a loose retaining bolt. A weepy O‑ring is common on higher‑kilometre cars, replacing the O‑ring is cheap insurance against mess and intermittent faults. Symptoms of a crook cam sensor include hard or extended starting, an occasional stumble at idle, slightly worse fuel economy, and OBD codes such as P0340/P0341.

Replacement is straightforward with basic tools. Disconnect the battery, unplug the connector, remove the single retaining bolt and lift the sensor/housing out. Swap the O‑ring, align the drive/flag as per the workshop manual, refit, and tighten the bolt to spec. Clear codes and take it for a drive, no special programming is typically needed as the ECU will sync itself. Use a quality OEM‑equivalent sensor, EF/EL parts are similar, but match by VIN to avoid minor variations. If the car runs with a failed sensor, it’s usually fine to get home, but fix it promptly to restore proper sequential injection and easy starts.

• Where relevant to your 1997 Ford Falcon six, a healthy cam sensor helps it start quicker, idle cleaner and sip a bit less fuel.
• During services, inspect the plug, wiring and O‑ring, replace the sensor if codes or symptoms persist.

Popular questions about the 1997 Ford Falcon camshaft sensor

Where is the camshaft sensor on a 1997 Falcon 4.0 six?
It’s mounted in the old distributor position on the side of the engine block. You’ll see a small round housing with a two‑ or three‑pin connector and a single retaining bolt. Access is from the top with basic hand tools.

What fault codes point to a bad camshaft sensor on an EL?
Common codes are P0340 (camshaft position circuit) and P0341 (camshaft position range/performance). You may also see long crank times and batch‑fire behaviour even if no light is on. Always check wiring and the O‑ring for oil intrusion before condemning the sensor.

Does the 1997 XR8 5.0 have a separate camshaft sensor?
No separate CMP on the XR8. The distributor’s Hall‑effect pickup provides the engine’s timing reference, so you won’t find a standalone cam sensor on that V8.
