The Multiquip RE503867 Oil Pressure Sensor Engine Side is a genuine OEM component designed for DCA150USJ3CAN and DCA150USJ2 ultra-silent diesel generator models. As a direct factory replacement, RE503867 meets the exact electrical and mechanical specifications required by the engine-side oil monitoring circuit on these units. This part is confirmed to fit DCA150USJ3CAN (including the Canadian FR variant) and DCA150USJ2 generators, making it a straightforward service replacement for field technicians and fleet maintenance crews.
Key Features
- Genuine OEM Sensor Accuracy — Manufactured to the precise resistance and pressure-response specifications required by the engine management circuit, ensuring accurate oil pressure readings rather than approximated aftermarket tolerances.
- Direct Engine-Side Mounting — Engineered to connect directly to the engine-side port on DCA150USJ3CAN and DCA150USJ2 generators, using the original thread pitch and connector interface for a clean installation.
- Confirmed Fitment for DCA150USJ Series — Verified for DCA150USJ3CAN, DCA150USJ3CAN (FR), and DCA150USJ2 ultra-silent diesel generator models.
- Protects Engine from Low-Pressure Damage — A correctly functioning oil pressure sensor triggers shutdown or warning alerts before low oil pressure can cause catastrophic engine wear, keeping generator uptime on track during long-duration power supply jobs.
- Electrical Safety Compliance — As an OEM part used in the engine protection circuit, RE503867 maintains the integrity of the generator's safety shutdown system, which is critical for compliant operation on commercial and industrial job sites.
The oil pressure sensor on the engine side of a diesel generator monitors the lubrication system in real time and sends a signal to the control panel to indicate whether oil pressure is within a safe operating range. If pressure drops below the acceptable threshold — due to low oil level, a failing oil pump, or a blocked passage — the sensor triggers a warning or automatic shutdown to prevent serious internal engine damage. When the sensor itself fails or drifts out of calibration, the generator may shut down unexpectedly, fail to start, or run unprotected without any low-pressure warning, all of which create significant risk to the machine and the power supply it supports.
