i have the bcm0133 brake sensor 2 signal to low code.
does anyone have any experience with this?

 

what is car MY?

 

It is a 2004 XC90, 2,5 l turbo:I have bought 2 yaw sensors from ebay and they didn’t help.

 

That code has no any yaw sensor relation.

Diagnostic trouble code (DTC) information
Condition
Note! This diagnostic trouble code (DTC) applies only to vehicles with DSTC/ESC.
The brake pressure sensors transmit signals to the brake control module (BCM) indicating the pressure in the brake system. If the control module registers an incorrect signal from any brake pressure sensor, then trouble code BCM-0130 or BCM-0133 is generated depending on sensor.
Note! As the cables to the brake pressure sensors can be switched physically upon installation, both sensors must be fault-traced when DTC BCM-0130 or BCM-0133 has been detected.
Hint:
Use the wiring diagram, signal description and the wiring's colour coding to determine which sensor the DTC regards.

Substitute value
Traction control is blocked.
SC is blocked.
Active yaw control is blocked.
Hint:
For more information about abbreviations, see: Bromssystem, förkortningar

Possible source
Open-circuit in the wiring.
Wiring is short-circuited to ground or supply voltage.
Damaged pressure sensor.
Internal fault in the control module.

Fault symptom[s]
Warning light antispinn on (applies to model year -2002)
General yellow warning light on (applies to model year 2003-)
Anti-spin not working
Stability function is not working
Anti skid function is not working

 

I’ve changed yaw rate sensor, bcm, pressure sensor: nothing helps still get anti skid message? If I change connectors on the pressure sensors the code changes from bcm 0133 to bcm 0130. Would appreciate any help.

 

so you need to try to replace pressure sensor.
If that does not help BCM itself is faulty.

 

Read above I’ve replaced bcm and pressure sensor
