First off the dumbass at the dealership read the codes wrong......he said I had a code 13 and 22. Said code 22 is variable valve timing oil pressure switch. First off, code 22 was actually 3, second off, i don't have a vtech engine that i believe has the variable valve timing (correct me if I'm wrong), and third off, according to the manual I picked up today an 89 Civic's trouble codes doesn't go past 20. This dealership mechanic is not very bright in my book. Anywho's....according to the manual, code 3 is the atmosphere pressure sensor and the 13 is the map sensor....judging how they both deal with "vacuum and pressure" I imagine what would cause those two to go off at the same time would be a vacuum leak right? What are your guys opinion?

code 22=vtec system malfuniction
code 3=MAP sensor
code 13= Atmosphere Pressure


Yes it is very good idea that it is to do with vaccum check the plug that goes into our MAP.I am guessing you have a motor swap???

 

nope...just the 1.5L inline 4. I went for a quick drive just now and at certain throttle positions I'll get a high pitch whistle and if i move the throttle a little more or a little less it'll go away. I bet that's my problem. Problem being sorting through all the vacuum line...UGH
