MAP sensor hose questions
im getting a p0106 code and its dealing with the MAP sensor and/or components. im wondering where that tine hose that connects to the sensor goes. i looked up pics of the wire harness and it just disappears into the harness and i have no idea where the other end is and where it might hook up. if someone could provide or at least point me to a complete diagram of where that hose goes all the way from end to end, that would help tremendously.
i recently rebuilt the engine and replaced the harness as well, so far the only other code im getting is p0300 for random misfire. could the previous code be causing the random misfire code?
over all as im no mechanic by any stretch, im pretty proud of my very first engine rebuild. cant ask for much more than it starting on the first crank.

Yeah, the really tiny one goes down into the passenger wheel well. From there it splits out to I think 3 locations, 1. is the HVAC 2. is the EVAP pump up beside the radiator on the driver side and 3. I cannot recall

That tiny vacuum line supplies vacuum for:
1. HVAC Damper door vacuum control motors on the HVAC Air Box under the dash. They control what vents the air comes out. If air comes out of multiple vents (other than selected) vacuul is not being supplied to the damper control motors.
2. Vacuum Reservoir Tank
3. A. I. R. (Air Injection Reaction ) Pump exhaust shut off valve. That system injects fresh air inside the exhaust manifold to check for proper O2 sensor operation and CAT efficiency.
4, To the solenoid valve that supplies vacuum to the A.I.R. Pump exhaust shutoff valve vacuum line. The solenoid is computer controlled and when commanded on allows vacuum to OPEN the A.I.R, output valve/supply piping/ outlet hose.
The nylon vacuum lines are very fragile, melt if exposed to battery acid and become brittle with age.
