PCM Pro-Tec Oil Pressure Switch Sensor – R020015A

Maintain your marine engine's oil pressure monitoring system with the PCM Pro-Tec Oil Pressure Switch (Part #R020015A). Designed for compatible PCM marine engines, this normally open oil pressure switch helps activate the engine's warning and protection systems when low oil pressure is detected.

Used on select 1989–1994 PCM engines, Ford GT40 engines, and PCM EFI applications, the R020015A switch provides a ground signal to the Pro-Tec engine protection system. Depending on the engine configuration, this signal can trigger a warning light, audible buzzer, or engine protection mode to alert the operator to potentially unsafe oil pressure conditions.

The PCM R020015A Oil Pressure Switch is a replacement component for compatible marine engines equipped with the appropriate oil pressure monitoring system.

PCM Pro-Tec Engine Protection

The PCM Pro-Tec oil pressure switch plays an important role in the engine's protective monitoring system.

When the switch detects the applicable low oil pressure condition, it provides a ground signal to the compatible Pro-Tec system. Depending on the engine configuration, this can activate a warning indicator, buzzer, or reduced-power operating mode.

This helps alert the operator to conditions that may require immediate engine inspection.

PCM GT40 & EFI Engine Compatibility

The PCM R020015A is associated with select PCM engines from 1989 through 1994, as well as compatible GT40 and PCM EFI applications.

Because PCM engine configurations and oil pressure monitoring systems vary, verify the existing switch part number, electrical connection, and engine specifications before ordering.

This is a normally open oil pressure switch, not a universal oil pressure gauge sender. Confirm that your engine requires this switch configuration.

Installation & Maintenance

Follow the PCM engine manufacturer's service instructions when replacing the oil pressure switch.

Before installation, verify the correct part number, thread compatibility, and electrical connection. Inspect the surrounding wiring and connections for damage or corrosion.

Important: Low engine oil pressure can indicate a serious mechanical or lubrication problem. Do not assume a warning is caused by a faulty switch without diagnosing the engine's actual oil pressure.
