Default OBD 1 code 22 on MAF engine

I have a 94 f150 with a 5.0 litre V8 MAF version.

I am getting " check engine" immediately on start and continuous.
OBD 1 code is 22 "map sensor"
This engine does not have a map sensor. I have cleaned the MAF sensor and replaced the air filter, but the problem persists.

Does anyone have any input? I am going to look for intake manifold leaks next.

Thanks!

Well, something is definitely wrong. Your truck should be giving 3 digit codes.

Lets not argue, you are reading 2 digit codes, OK fine, that used to be EEC IV. Don't have a clue about OBD 1 or when it came about. The same tester was used. The 22 used to be the MAP sensor, believe its called MAF sensor now. Am lead to believe both measure the density of the air and in later generations, the volume of air being processed into the intake system. Wish I could be of more help besides just part changing ideas.

I can read and I know OBDI. OBDI gives 2 digit codes up to '91. '92-'95 OBDI gives 3 digit codes. It's all OBDI up to '95. The fact you got a MAP code for a MAF truck should tell you that code isn't right.
