What Does C1267 Mean?
The ABS module has detected a malfunction in the right rear inlet (isolation) valve solenoid. This valve controls hydraulic pressure buildup to the right rear brake during ABS events. A failure prevents the ABS from properly modulating pressure on the right rear wheel, and the ABS system is disabled.
Common Causes
40%
Failed right rear inlet valve solenoid inside the ABS hydraulic modulator
25%
Wiring or connection fault between ABS module and inlet solenoid driver
20%
Contaminated brake fluid causing the inlet valve to stick
10%
ABS module electronic driver failure for the right rear inlet
5%
Power or ground supply issue to the ABS module
Diagnostic Steps
1
Perform bi-directional ABS solenoid testing to command the right rear inlet valve and verify actuation by listening for clicks at the modulator.
2
Measure the right rear inlet solenoid coil resistance at the ABS module connector — expect 3-6 ohms. Open or abnormal readings point to a solenoid failure.
3
Check ABS module power supply (battery voltage at power pins) and ground continuity (less than 0.5 ohms to chassis). Check the main ABS fuse.
4
Evaluate brake fluid quality — test for moisture content if a tester is available, and visually check for discoloration or particulates.
5
If electrical tests pass, perform a full brake fluid flush and ABS bleed cycle. Persistent code after fresh fluid indicates a mechanically stuck valve requiring modulator replacement.

The most common cause of C1267 (Right Rear Inlet Valve Solenoid Malfunction) is: Failed right rear inlet valve solenoid inside the ABS hydraulic modulator
Typical repair costs for C1267 range from $200 to $1,200, depending on the vehicle, location, and whether you do it yourself or go to a shop.
ABS cannot properly control pressure to the right rear brake during anti-lock cycling. Normal braking is unaffected, but ABS will not function correctly during emergency braking. Avoid hard braking on low-traction surfaces until repaired.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to C1267 to identify the root cause.
