    I have a 1993 Loyale, 5speed, 2wd, wagon. The speedometer broke inside the tranny and it will be awhile before I can repair it. The Engine Check light remains on with code '33' all the time as I'm driving so I assume that the cpu is obtaining speed sensor readings to make adjustments to the engine. What kind of adjustments does it make based upon this input signal? Leaner/richer fuel mix? Timing advance? Or . . . ? The manual doesn't explain such detail. I just wanto know what it's doing to my car when it thinks the car is going zero mph.
