Product Overview
A pressure fault, derate, warning, or implausible live-data reading may come from the sensor, but the connector, reference voltage, ground, wiring, and actual system pressure must agree before the sensor is condemned.
Caterpillar lists 274-6719 across a very broad range of engines, generators, compactors, excavators, loaders, trucks, and industrial equipment. The part number and three-pin connector provide a much safer fitment check than choosing from one example model.

Compatibility Notice
Northline Parts does its best to list all known compatible models, but the correct part may fit an application not shown.
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 this sensor cause an engine derate? A: Yes, a false pressure signal can trigger protection logic, but actual low pressure must be ruled out first.
Q: Does the long model list guarantee fit? A: No. Caterpillar serial-number and system changes make the 274-6719 parts-catalog match essential.
Q: How do I confirm this is the correct part? A: Match 274-6719, three-pin connector keying, thread and seal, pressure range, harness, and the machine serial-number parts record.
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.
