4. Subaru Crosstrek P0202 FAQs

What causes code P0202 to trigger on a Subaru Crosstrek?

On the Subaru Crosstrek (2.0L Boxer-4 (152HP) / 2.5L (182HP) / 2.0L PHEV Plug-In Hybrid (149HP)), P0202 is most frequently caused by Cylinder 2 fuel injector internal coil failure or Broken wiring or corroded connector pin on Cylinder 2 harness.

Where is the OBD-II port located on my Subaru Crosstrek?

On the Subaru Crosstrek, the 16-pin DLC diagnostic connector is located Under driver side steering column. Plug in any standard OBD-II scanner with the ignition in the ON position to read freeze-frame parameters.

Can I safely drive my Subaru Crosstrek with code P0202?

No. Cylinder 2 is completely disabled by an electrical circuit fault, causing hard misfires. Given that P0202 carries a Critical severity rating, we advise avoiding heavy towing or aggressive throttle inputs until sensor readings are verified.
