Subject: FTE Small - MAP Sensor Question

I just ran through the Test Code retrieval on my 88 Ranger with 2.9 engine.
I had the following codes.

O (KOEO)
22 - MAP Sensor out of Range
122 - Throttle Position Sensor below minimum voltage

R (Running)
12 - Cannot control RPM during high rpm test
73 - Insufficient TP change during Dynamic Response Test
74 - Brake On/Off (BOO) circuit failure (What in the world is this??)

Any ideas on these would be appreciated, however, my main question is the
location of the MAP sensor. In my book (Haynes Ranger & Bronco II, 83-92)
it shows the MAP Sensor as a cylindrical device mounted on the sidewall of
the engine compartment by the AC/Heater fan. I cannot find it anywhere over
there.

The closest thing I found with both an electrical and vacuum connection that
could be a MAP sensor was a flat 2"x3"(approx.) object mounted on the top
center of the firewall. Is this it? If not, where is it??

Thanks for your help.

Rick

if the tps has not enough voltage to it, and youre getting a problem with
that code 73 and that 122 , If im not mistaken another TPS will cure both of
them.
Im not sure about the location of the MAP sensor, but your local dealer would
probably show ya where it is if you have a chance to run it past them.
as for that Brake on off thig id ask the dealer too cause Ive never heard of
such a thing
Let us know on list please.. we're never too old to learn, and with these new
fangled computer systems.. the more knowledge ya get the better

rebuild of a Dana 60 including Detroit Locker and its
installation into a F-250, IFS to Solid front axle, rear disk

all the good advice and answers that you have posted
to the list in the past, second I worked at a Ford
assembly plant for 31 years and I think you have a
legitimate complaint, go get them. Hans>>

I wholeheartedly agree... couldn't have said it better
myself. David always helps when someone has a problem
and I'm glad we have someone like him on this list.

122,12,73 codes should be cured by installing a new Throttle position senor, its
an easy instalation. I also have an 88 Ranger with the 2.9 engine, and mine is
going too.
