these forums have helped me a lot since getting my zj. first time poster...
ok so im on break, i might miss info but i will be brief.
dtc #14. map sensor voltage too high or too low. tested the map with multimeter. tested good. good ground, good power, and sensor voltage drops when pulling a vac. (used a vac line and my mouth cuz i dont have a pump). then tested the tps. there was a ol reading somewhere around 2v but it went smooth other than that. both methods i got from here on the forums. troubleshootmycar.com or something like that. anyway, i didnt have a dad so this is me, a 38 yo man, learning on this baby. its fun and have been successful thus far but dont know enough about engines yet to know what else to check. in research prossess now but reaching out also.

fyi: i just changed the ccv elbows and the front hose. the rear elbow bootcould use replacing. i was getting blowback into the air box.
dont know what else to say and break is over. thx in advance!

 

i have a service manual on my phone and a haynes book.
