DTC P16A0 G Sensor Circuit: Description
A G sensor is installed on the front engine mount to detect vibration of the vehicle. The ECU uses signals sent from the G sensor to determine the vehicle condition, control the active control engine mount actuator, and detect malfunctions in the mount. If there is a malfunction in the G sensor, the ECU stops Active control engine mount operation.
DTC DETECTION CONDITION CHART
| DTC No. | DTC Detection Condition | Trouble Area |
|---|---|---|
| P16A0 | While the power source voltage of the G sensor (VGS) is 4.8 V or more and less than 5.2 V, the GL1 voltage is less than 0.03 x VGS, or 0.94 x VGS or more for 10 seconds or more. |
|
| While the power source voltage of the G sensor (VGS) is less than 1 V, the GL1 voltage is less than 0.03 x VGS for 10 seconds or more. | ||
| Power source voltage of the G sensor is less than 4 8V or 5.2 V or more for 10 seconds or more. | ||
| Difference between the current 11-fold G sensor value and the last 11-fold G sensor value exceeds the specified value. | ||
| The G sensor standard voltage in the ECU remains less than 2 V or 3 V or more for 10 seconds or more. |
