Parts for your 2010 Subaru Tribeca-Crank angle sensor

2010 Subaru Tribeca crank angle sensor — what it does, service pointers, and handy FAQs

Based on technical documentation, the 2010 Subaru Tribeca (EZ36 3.6‑litre H6) is fitted with a crankshaft position sensor, commonly called a crank angle sensor. The Subaru Service Manual for the 2010 Tribeca (Engine Diagnostics, EZ36) details CKP sensor operation and diagnostics, including DTCs such as P0335–P0339. Subaru’s electronic parts catalogue also lists a crankshaft position sensor (often referenced as PN 22053AA053) as an OE component for this model. Aftermarket application guides from OE suppliers (e.g., NTK/NGK) likewise specify a direct‑fit crankshaft position sensor for the 2010 Tribeca. So yes — this vehicle uses a crank angle sensor.

On the 2010 Tribeca, the crank angle sensor is the ECU’s timekeeper. Mounted at the rear of the engine block near the bellhousing, it reads a toothed reluctor on the crankshaft to tell the ECU exactly where the crank is and how fast it’s spinning. That live data underpins spark timing, fuel injection timing, and synchronisation with the cam sensors. If the signal goes missing or erratic, expect hard starts, random stalling, rough running, or a no‑start, plus a check engine light with codes like P0335.

It’s not a routine replacement item, there’s no scheduled interval. During major services, a sensible tech will eyeball the sensor connector and harness under the bonnet for rubbed insulation, oil contamination, or moisture intrusion, and make sure the wiring is clipped away from hot or moving bits. Because the air gap is fixed by the mounting, there’s no adjustment — if output is out of spec per the service manual tests, the fix is replacement.

Replacement is straightforward for a trained person: disconnect the negative battery terminal, unplug the sensor, remove the retaining bolt, and swap in a quality OE‑equivalent unit. Lightly clean the mounting face, seat the new sensor squarely, and tighten the bolt to the service‑manual torque spec. Reconnect, clear any stored codes, and perform an idle relearn if required. Using genuine or reputable-brand sensors avoids odd cold‑start behaviour or intermittent drop‑outs that can happen with cheap copies.

• Common signs of trouble: long crank, intermittent stall, no tach movement during crank, MIL on with P0335–P0339.
• Good practice: keep connectors dry and clean, fix oil leaks that can wick into looms, and scan for pending codes before long trips.
• When to replace: only when testing confirms a faulty sensor, damaged wiring, or contaminated connector.

Popular questions

Is the crank angle sensor the same as the crankshaft position sensor on a 2010 Tribeca?
Yes. In Subaru circles the terms are often used interchangeably. The factory manual typically says “crankshaft position sensor (CKP)”, while many parts catalogues and workshops will say “crank angle sensor”. They’re referring to the same Hall‑effect sensor that tracks crank position and speed.

Where is the crank angle sensor located on the 2010 Tribeca?
It’s fitted at the rear of the EZ36 engine near the bellhousing, reading a toothed wheel on the crank. Access is usually from above with some intake ducting moved aside, though some techs prefer access from underneath on a hoist depending on tooling and familiarity.

Can it fail intermittently and still start sometimes?
It can. Heat‑soak, internal sensor breakdown, or a marginal harness/connector can cause intermittent drop‑outs. Symptoms often worsen as the engine warms up. A scan tool watching live RPM during crank and a wiggle test on the loom help confirm the diagnosis before replacing parts.
