Check Engine Light on With Code P0133 on Suzuki Forenza

Problem overview

The Check Engine Light may illuminate accompanied by a code P0133 (bank1 O2 sensor) stored in the powertrain control module (PCM). This is commonly caused by a failed air/fuel sensor. Our technicians tell us a revised a/f senor and (PCM) software upgrade may be necessary to correct this concern.
