I pulled codes, and I think I got...

44 Thermactor Air Injection system inoperative (Right side).

and

52 Power steering pressure switch always open or closed

I dont know how to troubleshoot either of these problems... Or what they really mean.... I know that the Thermactor pump is your smog pump... but IM not sure what could cause it to fault out... I replaced the EGR and the codes still there...

I dont know much about the power steering... its seems like a fairly simple system... and I have no idea where the "Switch" would be. and I have a feeling its some type of electrical circuit and not a real switch...


Any help would be appreciated.

 

Could be a hose or vacuum line to the TAB and TAD solenoids (those do-hickys next to the coil on a V-8), air pump, etc etc...start with the simple stuff...

That is important because it supplies oxygen to your cats in the exhaust, and w/o that oxygen those cats will fail.

 

Did you turn the wheel a half or full turn when you did the test? Thats probably why you got a code 52.

 

the code 52 i wouldn't be to conserned with it. my'87 5.0 has had the same code for about a year now.

 

FOund the reason for my 44... One of the vacume lines from the TAD solenoid is disconected.. I found it flopping around Near my water pump... its a beige line... I have NO IDEA where I goes!!! I will take pictures tomarrow... it is the bottom line that conects the the sensor...

 

Posted pictures in my gallery... Kinda hard to see.. Please help.

 

On my truck, that vacuum line goes to a valve located just at the outlet of the smog pump. Basically directly below where you are holding the line in the picture. There should be a nipple on top of the valve for the vacuum line.

 

YES! Found it.. thanx so much... I reset the computer and after a wekk I will check to make sure the codes gone.. thanx!
