Compatible Models
We do our best to list all compatible models. Although this may be the part you need, your exact model may not appear below.
Compatible equipment / model

- 2012 Subaru Forester 2.5L H4 non-turbo
- 2013 Subaru Forester 2.5L H4 non-turbo
Product Overview
A check-engine light for mixture control or catalyst monitoring does not automatically mean both sensors are bad. Exhaust leaks, oil consumption, misfires, fuel-pressure problems, vacuum leaks, and a failing catalytic converter can set similar codes.
The upstream air-fuel-ratio sensor guides fuel correction while the downstream oxygen sensor monitors converter output. Their connectors, wire lengths, threads, and calibrations differ, so keep each sensor in its correct exhaust position.
Key Features & Performance
- One upstream air-fuel-ratio sensor
- One downstream oxygen sensor
- Crosses to 22641AA610 and 22690AA960
- For 2.5L naturally aspirated Forester models
- New aftermarket two-piece set
Replaces Part Numbers
- 22641AA610
- 22690AA960
Common Uses
- Replacing a sensor with a confirmed heater or response fault
- Servicing both sensors after harness damage or high-mileage diagnosis
- Restoring correct closed-loop and catalyst-monitor signals after other faults are repaired

Compatibility Notice
Northline Parts does its best to list all known compatible models, but the correct part may fit an application not shown.
Model, production date, serial number, connector, dimensions, installed options, and previous repairs can affect fitment. Compare the original component and reference information before purchase.
Frequently Asked Questions
Q: Which sensor controls fuel mixture? A: The upstream air-fuel-ratio sensor is the primary feedback input; the downstream sensor mainly evaluates converter output.
Q: Will this pair fix a P0420 code? A: Not if the converter is inefficient or an exhaust, misfire, or fuel-control problem is the cause. Diagnose the code first.
Q: How do I confirm this is the correct part? A: Match vehicle VIN, 2.5L non-turbo engine, both reference numbers, upstream/downstream position, connector keys, wire lengths, threads, and sensor-body shape.
Q: Is this supplied by the original equipment manufacturer? A: No. This is a new aftermarket item. Brand, model, and part numbers are used only to identify compatible applications.
