Code 22 MAP/BARO sensor out of range
1990 F250 7.3L E4OD 4X4
I used a $30 Ford OBD1 code reader from Kragen's Auto Parts to diagnose my truck because I have noticed the tranny is shifting erratically. Would the barometric sensor cause this even though the altitude of my town is only about 100ft. above seal level? I ordered a new baro sensor but will not get it for another 4 or 5 days. Will it cause any damage to the tranny if I continue to drive the truck? By the way code 22 is the only code that came up during the test.
Thanks, Jim

well im not sure what effect it has on the tranny if any. i know if the tach or spedo are wrong or don't read they will screw it up big time. better try not to drive it too. if it sticks in a low gear to long it might kill it due to heat. when i lost my first tranny it lost 3rd/od at the same time. then in 1rst/2nd limping it twards home we roasted the 1/2 planetary we dnt even have a load wehn we lost 3/4 and only an empty trailer when we roasted 1/2 -figure out whats wrong fast or it might cost you 2400$+

You need flawless operation of the tach and speedo....... also the FIPL sensor must be set to spec...... so it correctly sends IP throttle info to the PCM/trans.
Baro sensor really only comes into effect on high altitude, that is when it changes the the shift pattern so as NOT to burn up the trans due to lesser power from the engine. I have been told most BARO sensors are the same on all Fords just some use a vacuum line where ours do not.........

Thanks for the reply
I have already tested the FIPL, Tach sensor, MLPS, Speed sensor, and cleaned and greased the connections with die-electric grease. The transmission was rebuilt about 3 yrs. ago. I have never been happy with how it operated. It always seemed erratic and sloppy. About 2 weeks ago I tested and reajusted the FIPL and that helped a little bit. I will try and pull the connector off of the TECA today and clean and grease it. I will replace the baro. sensor as soon as I receive the new one I ordered yesterday. By the way the transmission has less than 20,000 miles on it since the rebuild.
Thanks, Jim

FIPL Replacement
To catch up on what progress I have made since my previous post, I replaced the barometric pressure sensor and cleared up the code 22.
But the trany was still erratic. I replaced the MLPS because the backup lights were not working, now they work.
I ran the code reader again and this time I noticed a continuous code 63 that I had overlooked before for the FIPL is less than self test minimum. Now I had adjusted it according to KJLYPW's instructions on another post and cleared up a FIPL code 23 at that time. After re-reading the code reader manual I realized that the code 63 was indicating a intermitant signal problem with the FIPL that was only happening while the truck was running. I replace the FIPL with a new one and my transmission problems have cleared up.
I want to thank everyone on this forum for all of the help and the good info that is not properly covered in the manuals. Jim
