Gm trouble codes 44 and 45

Code 44 is for the O2 sensor staying on lean, and code 45 is for the sensor staying on rich. The sensor is supposed to switch back and forth several times each minute if it is working correctly and the computer is controlling the fuel mixture.
The problem could be the sensor or a fuel problem such as an injector. The O2 sensor would need to be tested.

I have a 1994 Pontiac Grand am, 2.3 L with DTC codes 13 and 45. I already replaced the O2 sensor. What else could it be? The 8th digit of the vin is 3.

45 is rich exhaust, 13 is o2 open short or ground. How long ago did you replace the o2? You may have got a bad one. Code 45, Does it seem that the engine is running rich?

I have a 97 dodge caravan with a code 124555

It looks as though you have three fault number codes 12, 45, 55

12: Direct battery input to PCM was disconnected within the last 50 Key-On cycles.

As you'll see, there are two (2) exlinations for the number 45

45: EATX controller DTC present-an automatic transmission input DTC has been set in the transmission controller.

45: Park/Neutral switch failure-incorrect input state detected for the park/neutral switch.

The next set of code numbers are always good to see, means the computer can't find anything else wrong.

55: Completion of fault code display on Check Engine lamp.

I hope this helps you.

Thanks for letting, fix ya

Fault code 45- how do i repair it?

The code 45 in a later model is for the AWD control module causing harsh shifts. On a 2000 model the warranty per recall is 8 years and 100,000 miles. For your model you can try calling a dealer about recalls.
