2004 Ford Territory Camshaft Sensor: Fitment, Purpose and Servicing Tips

Technical sources confirm the 2004 Ford Territory (SX) 4.0L Barra DOHC does use a camshaft position sensor (CMP). The Ford Workshop Manual for BA/BF Falcon and Territory SX/SY (Section 303—Engine and Electronic Engine Controls) details CMP operation and diagnostics on the Barra I6. Industry data services like Autodata and Gregory’s manuals list test procedures and fault codes for the CMP on this model, and major parts catalogues for the SX Territory list a direct-fit camshaft sensor—collectively confirming it’s fitted and relied upon by the PCM.

On the 2004 Territory, the camshaft sensor’s job is to tell the powertrain control module exactly where the intake cam is in its rotation. That lets the PCM run true sequential fuel injection, manage variable cam timing, and keep ignition timing spot-on. It also syncs with the crank sensor so the engine fires cleanly from cold and doesn’t waste fuel.

It’s not a scheduled replacement item, but it’s worth a look during regular servicing—especially on higher-kilometre Territorys where heat and oil vapour can age the wiring and the sensor’s O-ring. The sensor is mounted at the front end of the cylinder head on the Barra I6, secured with a single fastener and sealed by an O-ring. If oil weep or brittle wiring shows up, sort it before it turns into a no-start or limp-home drama.

• Common signs it’s playing up: hard starting after a hot soak, intermittent stalling, rough idle, misfires under load, poor fuel economy, and fault codes like P0340/P0341.
• Quick checks: inspect the connector for oil ingress, cracked insulation, or green corrosion, make sure the harness isn’t rubbing on the front cover, and verify clean, stable power/ground at the plug.

1. Replacement tips: disconnect the battery, unplug the connector, remove the retaining bolt, and twist the sensor gently to release the O-ring. Lightly oil the new O-ring, seat the sensor squarely, refit the bolt, and reconnect.
2. Afterwards: clear codes, start the engine, and let it idle to relearn. A short drive cycle with a few steady cruise periods helps the PCM settle cam/crank correlation.
3. Parts choice: stick with quality OEM-equivalent sensors, cheap units can cause phantom cam/crank sync faults.

If issues persist after replacement, look beyond the sensor—wiring continuity, poor grounds, or mechanical timing faults (stretched chain, VCT actuator concerns) can mimic a bad CMP signal.

Popular questions

Where is the camshaft sensor on a 2004 Ford Territory?
On the Barra 4.0L, the CMP sits at the front of the cylinder head near the timing cover area. It’s held by a single bolt and sealed with an O-ring. Access is under the bonnet from the front—just watch for hot components if the engine’s been running.

What fault codes point to a bad camshaft sensor?
Typical PCM codes include P0340 (Camshaft Position Sensor Circuit) and P0341 (Camshaft Position Sensor Range/Performance). Before condemning the sensor, check the connector, wiring, and battery voltage, because low system voltage and harness damage can throw the same codes.

Should it be replaced as preventative maintenance?
It’s not usually replaced on a schedule. Instead, inspect it during services for oil contamination, harness wear, or brittle plastics. If symptoms show or codes return, replace it with a reputable brand and verify the fix with a road test.
