How to test for a bad ABC Pressure Sensor vdc on leads
2003 SL500
I am leaning towards a bad ABC pressure sensor =PS because sometimes 190 bar other times on start up 0 bar on my iCarsoft MB V3.0. Been that way for the last month.
what kind of voltages could I test for coming off the leads going into and out over the PS. looks like a brown/black wire red/black wire white/black wire ?
Thanks Peter, For some reason I thought there was only 1 ABC Pressure sensor for the entire system now one for each wheel. If that is the case then my theory is incorrect.
Maybe I should ask is there an overall ABC pressure sensor ?
ABC 1 (03-06) only has the system pressure sensor. ABC 2 has strut pressure sensors instead of strut plunger sensors. I think you have a weak pump. The system requires a certain volume to engage the pressure valve. If this volume is not reached, the pressure will stay at zero.

Yes there is one master, or pump pressure sensor.
On xentry diagnostics procedure and WIS it indicated four others (using my 2005 car as a reference) and showed one other sensor for each wheel.
As I said, no direct experience of this, just sharing mercedes documentation.
Always go with information from members who have direct experience of working on these systems.👍
