PCM Code P1220
Was at KMart car get together last night and was getting ready to leave and I get a Reduced Power and Service Active Handling message. Check engine light is on as well. Got all the codes to clear but 1. P1220. Every time I cleared it, it came right back. So something is hard failed. Looked up google when I had some time during work and came up with Throttle Position Sensor Circuit 2. Anyone else run across this code and have a different fix for it besides the sensor? If not I will get another one Monday and see if that fixes it. Could this be related to a bad battery? Volt gauge in the car was only reading 13 volts while it was running. Usually around the 14+ area. Oh yeah, car would start and idle but there was no throttle response what so ever. Goes into gear and moves forward and back just can't rev it. Had to tow it home and get it in out of the Arizona weather....
.....Any opinion is appreciated.

I had the same issue,I changed out my TPS and all is good now.The only bad thing was I was about 500 miles from home and had to drive in reduced engine power the whole way,I could get up to 55-60 on flat ground,but any incline I would be down to 25-30 mph,on top of it,it was on a sunday so there was no way I could have even got a new sensor anyway,I made it got a new sensor and all is good.

Thanks for the info. Good news for me I guess. I changed the battery today with the one I know is good from my truck and it didn't help. So I am glad to hear that the TPS will probably fix it. I know they do go bad. My car will not go anywhere though. No throttle response what so ever. Not even in park. I can idle anywhere I want to go though. What fun is that????
