Product Overview
A warning, derate, hard start, or pressure reading that jumps with harness movement may point to the sensor circuit. Compare electronic data with actual pressure and test the reference voltage, ground, signal wire, and connector before installing a new sensor.
The 197-8393 number is the primary fitment identifier. Caterpillar machines can use multiple similar sensors for oil, fuel, boost, or hydraulic pressure, so port thread, connector keying, and system location must match.

Model, production date, serial number, connector, dimensions, installed options, and previous repairs can affect fitment. Compare the original component and reference information before purchase.
Frequently Asked Questions
Q: Can a bad ground create a false pressure code? A: Yes. A weak sensor ground can shift the signal even when actual pressure is normal.
Q: Will this fit every C7 engine? A: No. Use the engine serial number and parts catalog because C7 sensor locations and numbers vary.
Q: How do I confirm this is the correct part? A: Match 197-8393, connector key, pin count, thread, seal, pressure system, machine serial number, and harness location.
Q: Is this supplied by the original equipment manufacturer? A: No. This is a new aftermarket item. Brand, model, and part numbers are used only to identify compatible applications.
