ABS code 22 leads to mechanical pressure control valve?

[ShoMe1More]

My ABS light has been on since I got the car.. I pulled my ABS codes and got #22 (LH Front Inlet Valve Open)

I reviewed the diagnosis procedure on another post and it points to "Replace brake pressure control valve block" as the final step.

I happened to check that mechanical rear brake pressure control contraption and noticed that the spring and connection that tethers the lever arm to the suspension was gone. So lever arm is just hanging from the valve block.

Now I bought the bias plugs and I'm going to take that lever arm off and install them. Considering the troubleshooting leads to "replacing" that valve block, could it be the case that the hanging lever is throwing my ABS system for a loop? And the bias plugs will fix the ABS code 22, tricking the system to think the valve block is now functioning?

Thanks

I don't think that's the valve block they meant. I think they mean the valve block contained within the HCU.

Basically, you'll need to replace your HCU.

The code refers to the block in the engine compartment.
You can also check the 2 relays that are plugged in down there.

If you search for abs code 22 you will find the following pin out test from SHOZ123.
Pin out test!

22 (LH Front Inlet Valve)

PINPOINT TEST BB: SOLENOID VALVE DIAGNOSIS


BB3 CHECK LH FRONT INLET VALVE


Disconnect valve body 19-pin connector.

Measure resistance between Pins 17 and 7.

Is resistance between 5 and 8 ohms?



Yes
REPLACE or SERVICE cable harness Circuits 495, 532C, 532D or 532E (Taurus/Sable). Circuit 495, 532C, 532D or 532G (Taurus SHO).

No
REPLACE valve body.

If only I knew what those circuits were. I just replaced my controller instead and the light went off.

You would have to dig up a wiring diagram.

Ok after reading the responses, tackling this is over my head... And my usual mechanic wasn't sure how to go about it either. Does anyone know a legit national chain, like Midas or any of them, that would be able to service our ABS systems?

If I were to take the code and diagnosis procedure in to one of those national chains would they even know what to do? Or would they sell me the bill of goods of "Well we have to pull our own codes, and then we can go from there.."

Taking this issue to a national chain is a mistake. I wouldn't.

You're in PA, there are a couple of SHO Specialists in the state who could take a look and sort it out without taking you to the cleaners. Reach out to Area 91 (Brian) here on the forums.
