C0627Variable Effort Steering Sensor Circuit High
- Generic OBD-II code · Chassis
- How the car detects it
- The high counterpart: the sensor signal sits above the top of the band the module treats as valid. In the Kelsey-Hayes design a healthy channel peaks near 4.4 V on a 5 V supply, so a reading close to the supply rail or beyond it points to a short to the reference or to battery voltage, or to a broken sensor ground that lets the input float high. That patent handles high, low and in-between levels as separate faults so service can tell them apart. Ford's variable-assist systems used such a steering wheel rotation sensor together with road speed, and Ford's effort patent names steering rate and angle as inputs. No maker publishes C0627. As with C0626, the module ignores the sensor and steers on a fixed or speed-only curve.
