Circuit Description

The OEM pressure sensor is used by the electronic control module (ECM) to monitor the lubricating OEM pressure. The ECM monitors the voltage on the signal pin and converts this to a pressure value. The OEM pressure value is used by the ECM for the engine protection system.

Component Location

The sensor location is dependent on the OEM’s application and installation. Use the OEM troubleshooting and repair manual.

Shop Talk

  • INSITE™ can be used to monitor the OEM pressure signal voltage going into the ECM.
