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.Google+

this has been a problem for my car. i bought a year ago and i already had to replace my transmission and now this i bought this car at 50000m. I am very unhappy with this model.
ENGINE LIGHT STAYS ON EVERY TIME I TAKE IT TO THE DEALERSHIP FOR REPAIR I AM TOLD THAT THR ERROR CODE INDICATES O2 SENSOR IS BAD...WELL I HAD IT CHANGED
3 TIMES...STILL THE ENGINE LIGHT REAPPEARS THE NEXT
DAY OR AFTER I DRIVE IT FOR AWHILE. I NEED HELP IT
THERE MUST BE SOMETHING ELSE RELATED TO THE O2 SENSOR
THAT THE MACHANIC IS MISSING OR OVERLOOKING. IF ANYONE OUT THERE HAS SEEN THIS PROBLEM AND KNOWS AN ANSWER

not fixed yet engine light just came on today loss of power !!!11-23-2012
Engine light on. Dealer replaced one o2 sensor, then the cat. converter, then the computer, now replacing second o2 sensor. This has been a 4 week process, and Suzuki makes it too complicated. Dealer( in IL) has to get pre-approval from Suzuki ( in CA) to fix anything, then wait for part to be mailed.

ck engine light on. pedal sensor out. put new one on,problem still exists. i have stalled out in traffic while this problem exists and almost been hit three times on the open road by other drivers. suzuki will not honor it under the warranty. they wont do a recall on the part. it is a safety hazard on the road. they say it is a part of routine maintenance. someone is going to get hurt or killed by this problem.
