C1274 Code: Meaning, Causes, and Symptoms | OBD2 Codes
C1274 – G-Sensor Error
C1274 Possible Symptoms
Anti-Lock Brake System (ABS) Warning Light ON,Engine Light ON (or Service Engine Soon Warning Light)
C1274 Possible Causes
Faulty G-Sensor,G-Sensor harness is open or shorted,G-Sensor circuit poor electrical connection
The 4WD vehicle measures the G-sensor signal to solve for 4WD vehicle unique problems. For example all 4 wheels are locked early on a low-friction road or control response is delayed when road friction coefficients vary. The HECU uses a filtered signal, as a supplementary value, to determine the road friction coefficient. This value is used for the accurate calculations of assumed vehicle speed, or precise division of control starting points.
