VZ esp failed code

[Martinivz]

Hey everyone, so I have a 2005 vz acclaim automatic

I’ve been having an esp code throw itself randomly as of late while driving, I replaced the right hand front and rear abs sensors and it went away for a few months and has now come back doing it again within the last month or so I have gone out and changed the abs module today (disconnected the battery then installed it then reconnected) started it up and it threw the code straight away off start up and it’s never done it on start up before only after driving for a while so I’m currently wondering is the abs module something I need to get cleared after changing or is it self clearing? And also what possible other problems could it be? I’ve checked brake fuse (read on another thread someone had the same problem and it was that) and I’m about to go out and change left hand side sensors but I’m wondering if there’s anything else to look at aswell?

have you tried scanning for code and then fixing it properly
was the abs module new or used, may have been faulty if used

I haven’t tried scanning yet as I’ll have to wait to Friday to get it scanned with a proper scanning tool and I only have a cheap toolpro scanner that’s coming up with no codes

The module was second hand from a wreckers came with warranty on it and was said to have no faults all the numbers matched up aswell

i had th same thing with a calais vz. turned out to be the ecu on its way out.
got a second hand ecu and got it cloned for $250

Ended up getting it scanned today and these are the codes that came up

C0245 wheel speed signal output fault
C0800 battery voltage out of range
C0161 brake switch circuit malfunction
C0131 hydraulic modulator pressure sensor fault

brake codes

The file isn’t showing up for me mate, I’ve started out by replacing the wheel speed sensors and the wires they are attached to as the wires that connect in the engine bay were all cracked at the plug and I’m guessing they were letting morning dew into them (I’m only getting the code of a morning when it’s cold through the day the code hasn’t thrown) and gunna try working my way up from there until I sort it out

Works for me on my iPhone.

cooked battery and charging system will throw ESP codes which you have codes stored

So I’ve tried a few things I’ve changed sensors all around the car and the wiring from the front sensors to the engine bay, have changed battery to a new battery, replaced abs module and it’s still doing it? What else could it be? I read somewhere that could possibly be from needing a wheel alignment is this true? And what other things could I be looking at? The weird thing is when braking it almost feels like the brake pedal gets stuck and is very firm to press in then when nearly at a stop it depresses and goes back to normal
