Most Reported On
C0267 is an OBD-II diagnostic trouble code meaning “ABS Pump Motor Circuit Open.” C0267 is a chassis/brake code (predominantly GM) meaning the electronic brake control module commanded the ABS pump motor on but detected no electrical feedback, indicating an open pump motor circuit. The pump rapidly modulates brake pressure during ABS events, so an open circuit prevents it from operating and disables ABS function, though normal base braking remains. It is frequently caused by wiring/connection problems or an internal module fault and should be repaired to restore anti-lock braking. This code is most commonly reported on 2000-2007 Chevrolet Monte Carlo, and 1992-2002 Cadillac Eldorado, with repair costs ranging from $300 to $1,200.
