100-10
Engine Oil Pressure : Abnormal Rate of Change 100-10
Engine Oil Pressure Sensor : Abnormal Rate of Change The signal voltage from the filtered oil pressure changes less than the specification during a specific duration of time.
The code is logged.
Events for the low oil pressure and filter restriction are disabled.
The value for the filtered oil pressure is set to the value for the unfiltered oil pressure. If diagnostics are active for the unfiltered oil pressure, the default value is used.
102-10
Engine Intake Manifold #1 Pressure : Abnormal Rate of Change 1785-10
