Product Details
Professional 161-1703 197-8393 3-Pin Low Pressure Sensor for Caterpillar Heavy-Duty Engines
The 161-1703 (also 197-8393) Low Pressure Sensor is a precision instrument designed to monitor delicate pressure balances within your Caterpillar engine’s vital systems. Whether tracking fuel pressure in a C15 truck, oil levels in a 3512B marine engine, or air intake in a C-12 industrial unit, this 3-pin sensor provides essential real-time data to the ECM. Accurate readings are critical for maintaining fuel efficiency and avoiding “Limp Mode” or unplanned downtime.
I. Advanced Capacitance & Strain-Gauge Technology
Our sensors utilize sophisticated architecture to ensure long-term reliability in harsh engine environments:

- High-Precision Signal: Produces a highly accurate proportional analog or PWM signal, ensuring the ECM receives a clear, noise-free representation of pressure.
- Rugged “Engine-On” Design: Built to withstand the high vibrations and thermal cycling common in 3516B/C Generator Sets and industrial power units.
- Direct Plug-and-Play: Manufactured to exact original factory specifications for a seamless replacement without harness modifications.
II. Extensive Application Across the CAT Fleet
The 197-8393 sensor is a versatile component found across a vast array of Caterpillar machinery:
| On-Highway Trucks | Reliable monitoring for 3126B, C7, C9, C-10, C-12, C-15, and C-16 engines. |
| Marine & Industrial | Trusted for 3508B, 3512B, and 3516B/C Marine Auxiliary units and SR4B Generators. |
| Construction & Specialty | Fits M325D L MH handlers, Challenger 65C/D tractors, and CPT372 Pumpers. |
III. Technical Verification & 12-Month Warranty
