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.

2008 Suzuki Forenza Reviews
I take care of about 8 suzuki forenza's for a company I work for, and overall they are a descent vehicle but to have too many problems for such a low mileage vehicle. Yes, the tcm as failed in many of them, some more than once. Im not very satisfied with the transmissions at all, they tend to always be doing something wrong. The engines are okay but could get much more mileage than what they do. If your looking to buy one of these buy them brand new with a warranty or your looking to put alot of many in it fast.
My Suzuki Forenza was bought new with 150 miles at the time I left the Suzuki dealership. Within a week I had concerns with excelleration which seemed sluggish at times. The service center at the Dealership told me that it was new and all of the parts needed to warm up a bit. I Was told that if I had concerns within a month to bring the car back. The sensor for the passenger side airabag was reported as broken because it read the bag was turned off when someone over 50lbs sat in the seat - never been fixed. the cover over the belts (pully & Tensioner) was melted due to friction (later recalled and fixed) but nothing else was addressed. I took my car in every 3 months or less in the first year because of excelleration problems. The TCM, Transmission Control Module was found faulty finally at around 85,000 miles almost 2 years later. This is covered under warranty at 32,000 miles and was fixed by a good faith agreement meant to discredit the arbitration decision that never came. The Suzuki dealership never found a problem. An authorized service center that had no ties to Suzuki found the issue. They described that the faulty TCM switch caused my car to shift into neutral while I drove. Since then the problem has returned and has proven this vehicle to be a very unsafe car. I took the car back to the dealership where the car was purchased and they have again found no problem. I wonder how many other Forenza drivers have had issues with excelleration?
