C0827Steering Effort Sensor Stuck
- Generic OBD-II code · Chassis
- Can trigger limp mode
- How the car detects it
- C0827 appears in no accessible code list, bulletin or manufacturer table, so no carmaker can be named for it. The title describes a steering torque signal that freezes: the value no longer follows the driver, either because a short pins the output at a supply rail or because the sensor delivers a constant value while the wheel is clearly being turned. An NSK patent shows how such a case is handled: outputs close to 0 V or 5 V (about 0.3 V and 4.7 V) count as faulty, the controller then works with the smallest of the last few good samples and fades assistance to zero over a set time rather than cutting it at once. Unlike the plausibility fault C0825, here the signal stops changing. The driver sees an EPS warning and the steering turns heavy within seconds.
