GPD 1815402 Oil Pressure Switch Direct Fit Replacement

The GPD 1815402 is a direct-fit replacement oil pressure switch designed to restore proper pressure monitoring to your vehicle's engine management system. This switch communicates critical oil pressure data to the engine control module (ECM), enabling the system to protect the engine from low-pressure conditions that could cause severe internal damage.

On modern vehicles, the ECM uses input from the oil pressure switch to manage engine operation and trigger dashboard warning indicators. On older vehicles, the switch may directly interrupt the ignition circuit to shut down the engine in a low-pressure event, preventing compressor or engine failure.

Key Features:

• Direct-fit replacement for OEM oil pressure switch
• Engineered to OE specifications for accurate pressure response
• Provides feedback to the engine control module (ECM) or warning light circuit
• Built from high-quality materials for reliable, long-term performance
• Backed by GPD's 1-year warranty against defects in materials and workmanship

GPD (Global Parts Distributors) has been a trusted name in automotive replacement parts since 1974, supplying quality components that meet or exceed original equipment standards. The 1815402 is sold individually and is designed for straightforward installation.
