Boost Pressure Sensor for Caterpillar
This boost pressure sensor, referenced as 194-6723 / 1946723, monitors intake manifold pressure to help the engine management system optimize air-fuel delivery and turbocharger response. It is an aftermarket replacement component for Caterpillar heavy equipment, serving as a cross-reference to OEM part 194-6723.
Overview
This boost pressure sensor for Caterpillar measures the pressure of the air entering the engine intake manifold and sends that data to the ECM. It supports consistent engine performance and helps protect against overboost or underboost conditions. It is designed for Caterpillar C7 engines and select loader and motor grader models.
Built For Performance
- Direct replacement design mirrors the OEM 194-6723 mounting and electrical connector layout
- Piezo-resistive sensing element provides accurate pressure readings across the operating range
- Durable aluminum or composite housing resists vibration and thermal cycling
- Sealed electronics guard against moisture and contamination common in engine bays
- Factory tested for output voltage and pressure response before shipment
Fits These Machines
- for Caterpillar C7 engine
- for Caterpillar 120H motor grader (8YL, 7AS prefix)
- for Caterpillar KAL series
On-The-Job Use
- Used on heavy construction equipment where turbocharger boost must be controlled during load changes
- Supports road grading tasks on Caterpillar 120H motor graders
- Applies to loader and haul truck applications powered by the C7 engine family
- Relevant for maintenance and repair operations in mining, quarry, and earthmoving jobsites

Good To Know
Q: Will this sensor fit any Caterpillar C7 engine?
A: It is designed as a cross-reference to the 194-6723 part that appears on Caterpillar C7 engines in 120H, KAL, and 8YL/7AS applications, but always confirm your engine serial prefix.
Q: What are signs of a failing boost pressure sensor?
A: Common signs include reduced engine power, poor fuel economy, and fault codes for intake manifold pressure. Replacing this sensor restores accurate boost readings to the ECM.
Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
