Code P250A 2015 Chevrolet Silverado Description

The engine oil level sensor/switch is normally closed with a proper engine oil level. The switch opens when the engine oil level drops below a calibrated level. The Engine Control Module (ECM) monitors the engine oil level signal circuit when the ignition is ON, and the engine is OFF. With the switch in the closed position, the ECM detects a low voltage on the signal circuit. With the switch in the open position, the ECM detects a high voltage on the signal circuit. When high voltage is detected on the signal circuit, the ECM will send a serial data message to the Instrument Panel Cluster (IPC). The IPC will then display a message on the Driver Information Center (DIC) or illuminate a low engine oil level lamp.
The Diagnostic Trouble Code (DTC) will be set when the ECM detects a high voltage on the signal circuit for three consecutive ignition cycles, followed by an ignition OFF event from 15 minutes to greater than 50 minutes, depending on engine oil temperatures.
