Question about 1990 Ford F150

Open Question

I have a 1990 ford f150 with a 4.9 engine. I have a thermactor air diverter solonid that I can't figure out where the vacuum hoses go to. Out of the top of the solonid it has a vacuum t. no hose is on one end. A hose is on the other end, it has a y t at the end. I think the one end goes to the canister, but don't have a cluue whre the other two hoses go. Any ideas? Thanks

Getting a code for smog pump

better check that info again. inspect belt routing diagram and vacuum diagram for thermactor pump and thermactor air system parts being present on your calibration. to my recollection there was no thermactor air used. where would they put all that plumbing?
pump, diverter valve, exhaust check valves, upstream and downstream air tubes? a ford has a label on the radiator support depicting the usage, hose color, and general vicinity in a schematic for ford technicians to identify. there is also a belt routing diagram that depicts the pulleys for the components. you dont have one...right?
you may have a code glossary for older vehicles. get the right manual at the library for free and restart diagnosis. or goto the emissions authorized repair facility and get the question answered after a quick self test

Air will not come out of a/c vents

Your controls are vacuum operated. Make sure that there is vacuum present...if not find the disconnect. Or, the vacuum "motor" that controls air direction has failed or is stuck.

Where is the acv valve located, the yellow vaccum line is broken and I'm trying to replace it, and also would this make my truck run rich, and flood?

Right hand side of engine compartment, valve has 3 or 4 large (3/4") or so hoses going to it. 1 goes to air pump, 1 goes to exhaust, 1 goes to catalitic converter, 1 to air cleaner.
also 1 vacuume line from manifold vacuume 15" vacuume or better. If vacuume diaphram is ruptured or vacuume line broken resulting vacuume leak can cause lean misfire. If pump of diverter valve does not send air to correct area then engine will fail somg check and regester a high co reading. (runs to rich).

Suddenlt our vehicle driver side only blows cold air and the pasenger and rear vents blow the correct temperature setting.

You have a air box heater box air divert valve stuck you will need to replace it first start by looking under the dash passenger side you will see a round part with some vacuum hoses coming off from them start engine switch your location function switch see if working on divert er vacuum you most likely will have to replace your divert er valve.

Engine light cam on, used code scanner, got code #44, thermactor air control system, what do i need to do?

A code 44 on a 1999 caviler ? for 1999 the code should be like a po**** type of code, unless the is the wrong year. a code 44 for an older caviler is the code for a lean exhaust this would be like a 1995 and older, check the engine for any vacuum leaks, listen for any hissing noise you may have a broken or disconnected vacuum hose, if no leaks are found then replace the oxygen sensor, this should take care of the problem is no vacuum leaks are found.

I have a 2006 Ford Expedition. The Air

you have a vacuum loss to the ac control head, the motors that divert air are vacuum operated, if you loose vacuum the system goes to defrost for safety reasons, the vacuum comes from the engine, then goes o a plastic vacuum tank under the hook start there, it is a 3/16 id hose.

1998 328i.. Got a 1421 and 1423 code...not sure where to start...

1997 BMW 328I 2.8L Customer Concern: MIL is on with trouble codes P1421 and P1423, for incorrect secondary airflow on both cylinder banks. Tests/Procedures: 1. Perform a functional test of the Air Injection Reaction (AIR) system. Tee a vacuum gauge into the vacuum hose attached to the diverter valve, located on the cylinder head towards the front of the engine.

2. Allow the vehicle to sit over night. Start the engine (cold) while monitoring the amount of vacuum on the gauge at startup. At temperatures from -10 to 40 degrees Celsius, there should be at least 17 inches of vacuum. At the same time, the AIR pump should run and pump a large volume of air into the exhaust. Potential Causes: A.I.R. Pump
Air Pump Relay
Restricted Cylinder Head
Diverter Valve
Tech Tips: These codes are related to a problem detected in the Secondary Air Injection system. Scan tools with BMW software include a feature to command the AIR pump on and off. The pattern failures for these codes are the AIR pumps due to leaks in the diverter valve and moisture or condensation in the AIR pump.

Possible fix but not all items. Just areas to look at:
Confirmed Fix - A.I.R. Pump - A.I.R. Diverter - A.I.R. Pump, Air Injection Reaction Diverter (AIRD) Valve - Air Injection Reaction Diverter (AIRD) Valve - Check Valve, Secondary Air Pump - Diverter Valve Vacuum Lines

Making a soundlike a hole i n muffler

Depending on what engine is in your truck, I think that canister does not have a hose connected to it. A common source of that exhaust leak noise is from a broken thermactor check valve in the back of the engine. If it is a Ford V8 look in the back of the engine closest to the firewall. There is a Metal pipe that is bolted to the back of the left & right cylinder head. in the middle of the pipe is a bulblike checkvalve that has a 1" hose that suppose to be connected to the check valve... if the hose is not connected look to see if the top of the check valve has rotted off and the broken piece is still clamped in the inside of the hose. The easiest way to replace the valve if it is broken is to unbolt the tube forn the left & right side of the rear of the cylinder heads and fish the tube out and clamp the tube on a bench vise. Do not distort the tube or you will struggle to bolt it back on.
