2012 Toyota 200 with P2173 Fault Code and Limp Mode - How to Fix

Model: 2012 200 Fault Code: P2173 Posted: 2015-02-04 10:16

I'm experiencing a P2173 fault code on my 2012 Toyota 200, which is triggering limp mode. The vehicle runs poorly and I'm looking for a reliable solution. Can anyone confirm what causes this code and how to diagnose or fix it? The issue appears related to fuel mixture problems, possibly due to a faulty oxygen sensor or fuel injector malfunction.
