90TII rx7

I found a old pic on the forum and the description is just rack solenoid. So fig i would just try and post my pic of it. Im trying to find out the part number so i can order one from mazda. Of anyone has the part number i woild appretiate it. In case ya cant tell it broke of the nipple that comes straight out.

They are typically available used for a good price. Also, you can get solenoids off an FC, they are the exact same.

I cant even find what it is called only thing i come across is rack solenoid. That does my guy at mazda no good. The car is not at mazda its at another car place getting fixxed. So i cant go to the car and use any diagrams

What Dale said. Or if you are set on buying a new solenoid make sure to double check dealer prices, because some Mazda dealers might overcharge you for it. Do a price cross reference with the Atkins Rotary prices. I believe they sell the 3-way solenoid for $65 new.

Part number 1480-13-240A

The OP poses an interesting question. There are 5 different part numbers (I get different part numbers than post #2 BTW), but the solenoids all appear similar. I thought they were mix and match, but are they???

My best guess has been the p/n depends which port they have the tiny air filter pre-installed on.

i just bit the bullet and bought the charge control part number... 13-240 number 3.
it was 60 something bucks. he said they are all 13-240 plus whichever number or 18-740A whichever number. God I hate it but if it s not the right solenoid I may just buy all of them, after going down there and seeing the car all apart I don't want to have to pay them to do it again.

I would imagine different part numbers putting them as different resistance inside for measuring the performance and not just being an open and close valve.

Guess they are all the same, except for the filter

But why all the different part no's?

Another Mazdaism???

FDs are OBD1 and therefore too stupid for something like this. It's literally just a solenoid valve that changes where vacuum is ported to. They all have the same internal resistance.

All the solenoids are the same. The part number differences are just for which port has a filter. The filter can be pulled off and installed where it needs to be or pulled off the old solenoid in the event the new solenoid doesn't have one.

Then why are there FIVE different part no's???????

Bottom line is they are the same though

Slightly old bump... but it happens when you actually search.

What about FB and FC solenoids, and other Mazda solenoids like from a B2000 pickup?

I ask because I have a broken one from my FD, but I have 7 FCs laying around, and I want to scavenge one.... I guess I will just put it to the same test with vacuum, pressure, and 12v's. That will tell me. Just wanted to know if anyone could give me a faster answer.

Also according to the number stamped on the side of the OP pic, that solenoid is from a FC, OR they are all in fact the same.

My local mazda parts guy told me the number on the side meant nothing to him. The car is pretty low miles i would believe it was the original solenoid that was broken.

the number on the side is the musubishi number, because they are made by mitsubishi, doesn't reference anything in Mazda land

there are basically two, one has airflow from port A to port B, the other has airflow from port A to port C.

then once you add the filters, if any, you get 5 different numbers.

if you think that is bad try a Ford F250, they use around 100 different driveshafts for that

the 1480/1481 solenoids start life on the 1981 Rx7, and are used on all kinds of Mazdas up until the late 90's.

I figured they were. No matter which of my cars I go to its basically the same rack of solenoids from all 3 generations. Just wanted to be sure.

According to Ray Crowe, not all solenoids are the same. He gave me a run down of the quantity, part numbers and their purpose:
(3) 1480-13-240A. Double throttle control, charge control and charge relief.
(1) 1481-13-240A. Pressure regulator control.
(2) 1482-13-240A. Secondary air bypass, EGR.
(1) N390-18-741. Turbo control.
(1) N3A7-18-741. Secondary air switching valve.
Of course, they all look the same and I had mixed them all up during testing. Ray said not to worry because the painted numbering/lettering sequence on the solenoid identifies what they are for. Ray said that there are two rows of painted numbers on each solenoid: the upper and the lower rows. The lower row identifies the solenoids as follows:
"1" corresponds to part number 1482-13-240A. Secondary air bypass, EGR.
"2" corresponds to part number 1481-13-240A. Pressure regulator control.
"3" corresponds to part number 1480-13-240A. Double throttle control, charge control and charge relief.
"82" corresponds to part number N390-18-741. Turbo control.
"17 corresponds to N3A7-18-741. Secondary air switching valve.

Well that is good to know, but I wonder what the real difference is?

I checked them using pressure, vacuum, 12v, and a gauge. They all test identically.

Some others have said the only difference is the location of the filter, or the lack of it, but if the above info is correct then that's not true.

Painted numbers 17 and 2 have the filter in the same location, as well as 1 and 82.

When only the inlet or outlet port breaks off like the picture, they are easy to fix.
All that you need is:
(1) 1/8" OD brass or other metal pipe like from a hobby shop.
(2) 1/8" drill bit and drill.
(3) some good epoxy like GB Weld.
(4) An inventive logical brain that allows one to analyze a problem and come up with a solution.
