ABS warning

[Frustrated Civic]

Hiya folks.

I have an 09 2.2 diesel with an annoying ABS warning light…..

The warning came on a few months ago and showed a fault with the OSR sensor. I eventually got round to replacing the offending item o oh to find that a fault was now also showing for the OSF sensor. A pain in the butt, but got that replaced too.

The warning light now periodically comes on, and then resets when the ignition is turned off for a period of time. There seems to be no pattern for it in terms of speed, journey duration etc. Sometimes I can do my 20mile commute and it’s fine, other times I might go a mile and it comes on.

I’ve had all the sensors disconnected and the contacts cleaned up, but the problem persists.

No faults are being stored on the CPU.

anyone else had this, or any ideas on how to remedy it?

TIA
