ok i did the key on engine off test on my 1995 f-150 5.0 and it gave me a code 22 and that is supposed to mean "MAP (vacuum) or BARO signal out of range - MAP" what does it all mean bazzle!!!!!! and i still cant find my damn PCV valve. i must be blind. i am going to feel like an idiot when someone comes over who knows what they are looking for and says "it is right there" in plain sight. does anyone have a picture so that i could see the location of the PCV valve or the MAP sensor.
The MAP sensor is mounted on a bracket just above the HVAC stuff on the passenger side of the firewall. The PCV valve is tucked in behind the intake manifold just about where the MAP sensor is mounted.
22= map or bp sensor out of range,
engine off, map/bp sensor is bad
engine running, sensor is bad, or there is a vacuum leak
so since i did the test with the key in the run position but the engine off and got the 22 then i need a new map or bp sensor? does it sound like the map/bp sensor if the check engine light comes on when i start the truck or having it idling but when i let off the gas and then get on it again quickly, the light goes off. also the truck does not feel like it has all of its power.
