This is on my do list.

 

Great advise guys,

I had the same problem and just cleaned the connectors and now is running great. Test drive it and no problems with the steering.

Good job!

 

did you extend the overflow hose to avoid it possibly happening again?

 

Yes, I did thank you very much. I appreciate your help and input.

 

What's is the best way to get to these two connectors please help!

 

Remove factory air intake, it's easy.

 

I've been having PS problems too. Opened the fuse box in engine bay and this is what I found. Some of my relays are cracked and I have no idea how. Which one is PS fuse? U think these cracked ones have affect on PS? One controls PS amongst other things.

 

Some one tried to remove them. they are a bitch to get out. The fuse you are looking for is right at the positive terminal at the battery.

 

im having the same prob just started last night. worked fine all day went home turned it off and the problem started. also idk whats going on with this but the DSC and traction control is now not working ether... any help would be awesome. im going to clean the power steering connectors here in a few mins hope it fixes at least one of these problems

 

Guys if you have this problem even after cleaning the connectors, make sure you check/change your harness before touching the ecu module or rack. Most of the time that's the problem and fixes it right away.

 

i cut my connectors and soldered my wires together and used a multi meter to test all the way from the EPSM down to the rack and there is a constant flow
my power steering is completely out. Also when i did this i cleaned every possible connection with cleaner. I was wondering if there is a way to read a "code" set out by the electronic power steering on my 2004??

 

Does anyone know much about the PCMs for power steering compatibility wise. I found a bunch online but none with exact matching part numbers. i had a problem with this before when i had to replace my main pcm.

My power steering pcm is "F151-67880 00" "J601-112590 0F10"
There's two lines of numbers the first one matches most of them but the second one is where it doesn't match up.

 

Are you sure it's the PCM? It's more likely the rack itself. Mazda can read the codes if you have one.

 

The latest version for a 2004 S1 power steering module is part no. F151-67-880D. You have the original version. As Mazda revises the part they add a letter on the end starting with A, then B, then C, and so on.

There seems to be some conflicting reports on the forum about whether a dealership tool is needed for logging a different EPS module into the pcm CAN communication network or not ...
