Parts for your 2006 Ford Territory-Crank angle sensor

2006 Ford Territory crank-angle-sensor: what it does and how to look after it

Based on Ford Australia SX/SY Territory workshop literature for the 4.0‑litre Barra petrol engine and standard OBD‑II engine management documentation, the 2006 Ford Territory is fitted with a crankshaft position sensor (often called a crank‑angle sensor). The PCM relies on this signal to control spark, fuel injection timing and to confirm engine speed, so it’s absolutely relevant to the model.

On the 2006 Territory, the crank‑angle sensor reads a toothed wheel on the crankshaft and tells the engine computer exactly where the crank is at any moment. That lets the PCM fire the injectors and coils at the right time, keeps idle stable and enables quick, clean starts. Lose that signal and the Territory will usually crank but not start, get a weak or noisy signal and it can stumble, stall, or throw a check‑engine light with codes like P0335/P0336.

There’s no scheduled replacement interval for the sensor, it’s a solid‑state part designed to be “fit and forget”. Still, as part of routine servicing, it’s smart to give it a quick once‑over:

• Visually check the wiring and plug for heat hardening, oil contamination or broken clips.
• Make sure the harness isn’t rubbing on the pulley, crossmember or A/C lines.
• If the engine has had front or rear main seal leaks, clean away oil that can wick into connectors.

When replacement is needed (age, heat or damage), the job is straightforward for a competent DIYer or any workshop. Expect to access it from underneath, it’s mounted to the block to read the crank’s reluctor wheel. Common steps include disconnecting the battery, safely raising the vehicle, unplugging the connector, removing the retaining bolt, swapping in the new sensor with a light smear of clean engine oil on the O‑ring, then refitting and clearing any stored codes. Always tighten the retaining bolt to the manufacturer’s spec and route the loom in its clips to avoid future chafing.

After replacement, a scan tool check for live RPM during cranking is a quick way to confirm the sensor is talking to the PCM. If issues persist, inspect the wiring back to the PCM and verify the air gap/reluctor condition. With a healthy crank‑angle sensor, the Territory starts sharper, idles sweeter and keeps its fuel economy on song across Aussie and Kiwi roads.

• Where is the crank‑angle sensor on a 2006 Ford Territory?
  It’s mounted to the engine block facing the crankshaft’s toothed wheel. Access is typically from under the vehicle, remove splash shields as needed, then follow the harness to the small sensor secured by a single bolt. Exact access can vary with trim and accessories, so a workshop manual view helps.
• What are common symptoms of a failing crank‑angle sensor on this model?
  Long crank or no‑start, intermittent stalling when hot, rough running, random misfire, a dead tach during cranking, and a check‑engine light with codes like P0335/P0336. Heat soak can make it worse after a short stop.
• Is it safe to drive with a dodgy crank‑angle sensor?
  Not really. It may run poorly, stall at the lights or refuse to restart. If it’s showing early signs, arrange repair soon, if it won’t start or stalls repeatedly, organise a tow to avoid being stranded.
