I have been communicating with a member on here about replacing a pressure sensor on the valve block on the dynamic roll system (ACE) to others. No. 6 in the picture.


My theory being this is the most economic way of replacing the components on the Valve Block .
The part number is car part 55CP13-02 Car Brake Pressure Sensor Switch for Land Rover 1999-2003 3-Pins Oil Pressure Sensor 55CP1302 car part. Although it says brake pressure switch it would be or can be an oil pressure switch for the Valve block as I understand it.

My thinking is as the code CIBI1-1D relates to the pressure control valve coil , Its not really at fault here as it may not be receiving no signal from the pressure sensor . Is there anyone on here that might help in this theory.

The error message relates to the control valve solenoid which is number 18 on your diagram. Changing the pressure transducer won't help if the solenoid if faulty.

Refer to the electrical circuit diagrams and check pressure

a new pressure control valve solenoid coil as required

Many thanks for your reply , I think by reading the workshop manual this is not a replaceable service part.
I believe though by removing the coil off the valve block, I can only get this by removing from a s/h block , I think its removable , so I am willing to try this . This was my first option , believe or not. I am trying to cut corners with the easy option of the pressure transducer thus avoiding the more difficult route of finding a s/h unit that is no more of holding components where the block is corroded.

Off to hunt.

Sorry I missed the earlier offer on this thread.

In all my years, I've only ever seen one faulty DCV solenoid. Every other one has been internal to the valve block

Hi Mikey any old Valve blocks I can try a dcv on mine first before I look for a complete one ? Please.
