2000 Expedition Trans Question
 

I have a 2000 Expedition, Codes are as follows: P0743, P0755, P1747, P0443, P1451, P0135, P0155, P1409, P0141, P0161.

When put in gear motor starts to miss very bad. When put in 1st truck will move but still misses very bad
163,000 miles
Any help would be apprecitive.

In trying to decipher those codes, many relate to the oxygen sensor heater circuit. Check all the fuses first. From what I was able to conclude most if not all your codes are from an electrical failure supplying several systems.
For now I would start with all the fuses and replace any that are bad and see what you uncover. hanky

Fuse
 

I found fuse number 23 under the food blown, I replaced the fuse and everything seems normal. The fuse description is HEGO Sensors,Canister Vent, Automatic Transmission, CMS Sensor

Any Idea what may have blown the fuse?

If it doesn't reoccurr, I wouldn't worry about it. If it does blow the fuse again, there apparently is an intermittent problem. It could involve any of the circuits the fuse protects. Lets see what happens before we get overly concerned OK. ,,,,,,,,,,, hanky

Thanks
 

Thanks hanky, The truck is new to me, the only thing I have a concern with is the shift from first to second is abroupt if I'm on the gas. If I baby the gas its fine. Could this be the problem? would this be the first shift module is this hard to change?

Thanks again

Wayne

At this point I don't think so. Trying to do this right we need to do some more checking. Sometimes, when you have corrected a problem the computers need time to adjust to a new shift schedule. Drive the vehicle normally for a while and see if the problem lessens or goes away completely OK? Patience pays. ,,,,,,,hanky:)

I have the same problem with my 02. Did you find the problem?

Fuse number 23 under the hood
