Parts for your 2008 Subaru Exiga-Crank angle sensor

2008 Subaru Exiga crank angle sensor (crankshaft position sensor)

Technical sources including the 2008 Subaru Exiga (YA) Factory Service Manual – Engine Diagnostics, Subaru technical training notes on the EJ-series engines, and the Subaru FAST electronic parts catalogue confirm this vehicle is fitted with a crankshaft position sensor (often called a crank angle sensor). It’s a core input for the ECU on both the 2.0L and turbo EJ variants used in the Exiga’s launch year.

The crank angle sensor tells the ECU exactly where the crankshaft is and how fast it’s spinning, so it can time spark and fuel with precision. On the EJ engine it’s a magnetic pickup-type sensor reading a toothed reluctor, and without it the car may not start or can cut out unexpectedly. Common signs it’s on the way out include an intermittent no-start when hot, random stalling, rough running, and a Check Engine Light with codes like P0335 or P0336.

It’s not a scheduled replacement item, but it’s smart to give it a once-over during big services—especially around timing belt work—checking the wiring, connector, and for oil weeps under the bonnet that can contaminate plugs. The sensor sits at the rear upper area of the engine block by the bellhousing. Access is from the top, on turbo models, removing the intercooler helps, and on non-turbo, moving the intake ducting aside usually does the trick.

Replacement is straightforward: disconnect the battery, unplug the connector, remove the single retaining bolt, and ease the sensor out. Lightly clean the mounting bore, seat the new sensor squarely, and tighten the bolt snugly to factory spec—don’t overcook it. Reconnect, clear any stored codes, and road test. Use dielectric grease sparingly on the connector to keep moisture out, and avoid bending or twisting the harness. There’s no adjustable air gap on this setup, so if the ECU still complains after fitting a quality sensor, inspect the reluctor, wiring, and grounds.

• Typical faults: P0335, P0336, hot no-start, intermittent stall.
• Good practice: inspect at major services, especially with timing belt work.
• Use quality OEM-equivalent parts to avoid false triggers and misfires.

Popular questions

Where is the crank angle sensor on a 2008 Subaru Exiga?
It’s mounted high at the back of the engine block near the bellhousing. Under the bonnet, look straight down behind the intake manifold area. On turbo models, removing the intercooler gives clear access, on non-turbo, shifting the intake ducting usually suffices.

What symptoms show a failing crank angle sensor?
Intermittent no-start (often when hot), stalling at idle or when coming to a stop, rough running, and a Check Engine Light are classic. Scan tools commonly show P0335 or P0336. Because the ECU loses a critical timing signal, the engine can cut out with almost no warning.

Is it OK to keep driving with a dodgy crank angle sensor?
Not recommended. A failing sensor can cause sudden stalling and no-start situations, which isn’t safe in traffic. If the light’s on and symptoms are present, diagnose promptly and replace the sensor or repair the wiring before the issue strands the car.
