ACDelco 84868124 Steering Gear Pressure Sensor

The ACDelco 84868124 Steering Gear Pressure Sensor is a GM Genuine Part designed to monitor hydraulic pressure in the power steering system and communicate critical data to the vehicle's Engine Control Module (ECM). This OEM sensor plays a vital role in maintaining smooth engine performance during steering maneuvers, particularly at low speeds and during parking.

Key Features:

• GM Genuine Part engineered to rigorous OEM standards and backed by General Motors
• Monitors steering system hydraulic pressure and sends voltage signals to the ECM
• Helps prevent engine stalling by allowing the ECM to compensate for power steering load
• Enables automatic idle speed adjustment during steering operations
• Direct replacement for GM part numbers 23372526, 23452538, and 84586426
• Designed for installation on the steering gear assembly
• Built to strict federal safety and quality standards

How It Works:

The steering gear pressure sensor contains a diaphragm that activates when hydraulic pressure increases during steering input. When you turn the steering wheel, especially at low speeds, the power steering system creates significant load on the engine. The sensor detects this pressure change and signals the ECM, which then increases engine idle speed to compensate for the additional load demand. This prevents the engine from bogging down or stalling during tight maneuvers and parking.

This genuine ACDelco component ensures optimal performance and reliability for your GM vehicle's power steering system. Factory original equipment quality guarantees proper fit and function.
