C1516 is an OBD-II diagnostic trouble code meaning “Roll Rate Sensor Signal Fault.” C1516 is a manufacturer-specific chassis code (documented on Ford/Lincoln) indicating an invalid or out-of-range signal from the roll rate sensor. The roll rate sensor is part of the rollover/stability sensor cluster and reports the vehicle's side-to-side roll motion, which the stability and rollover mitigation systems rely on. When the module cannot validate this signal against other inputs, it disables the affected stability functions and sets the code. Meaning can vary by maker, so verify against the factory manual. This code is most commonly reported on 2006-2015 Mazda MX-5 Miata, with repair costs ranging from $200 to $1,200.
