I am having all kinds of problems with my '94 850 Canada, now I am getting under A2, 2-4-3, Throttle position sensor outside voltage range, 1-3-2, battery voltage too low or too high. Also under A1, Throttle pos'n sensor too low. I clear the codes and all is well. Two minutes later my yellow arrow flashes and the Lambda light comes on. Should I just change this sensor? I have a new battery, why would the voltage be too high or too low. I guess by now you recognized me as pretty inept at this. So all and any suggestions would be more than appreciated. Have a great New Year

Did you re-read the codes after the second occurrence of your problem?

Your problem sounds like a PNP switch that is failing but the codes that you posted don't really point to that.

Sorry, I kind of left you in the dark here. I changed out the PNP switch and thought I had the problem solved. This is when the light started to flash again and these are the codes I got after clearing them again. Thanks
