Covers over 25 million vehicles worldwide

Includes 32 sensors for passenger and commercial vehicles

Withstands vibration loads up to 67 g

Has a burst pressure tolerance of up to 4,700 bar

6 reasons why

Stable pressure readings

Each sensor meets OE specifications and delivers accurate fuel pressure data to the control unit. The signal is reliable during both normal driving and demanding operating conditions, enabling the correct fuel delivery and a smooth engine response.

Fast signal responses

Modern fuel systems react at lightning pace to pressure changes. Our sensors deliver a response time below 2 milliseconds, so the control unit gets the pressure data it needs almost instantly.

Ideal for high-pressure GDi operation

Gasoline direct injection systems run at very high pressure. These sensors support typical GDi operating ranges between 100 and 500 bar.

Rugged construction

Sometimes, fuel system components come up against significant vibrations and tough operating conditions. Our sensor's hermetic construction withstands vibration loads up to 67 g. The unit also tolerates burst pressure up to 4,700 bar.

Dependable operation in extreme temperatures

Fuel system sensors operate close to the engine and fuel rail, which can lead to high temperatures. Our sensors deliver accurate readings in these conditions to support performance anywhere, anytime.

Extensive passenger and commercial vehicle coverage

Our range covers more than 25 million vehicles with a portfolio of 32 sensors. Applications include leading passenger and commercial brands: BMW, Mercedes-Benz, Renault, VAG, Tata, and Volvo. Whatever you need, Delphi delivers.

Exceptional performance in tough conditions

How LFP & GDi sensors work

A fuel pressure sensor measures the pressure inside the fuel system. It then sends that data to the engine control unit. The control unit uses this signal to regulate fuel delivery through the injection system. When the pressure reading is accurate, the engine can maintain the correct fuel flow during idle, acceleration, and load changes.

Our innovative sensors deliver ultra-fast and stable pressure signals in normal and demanding operating environments. The response times are sub-2 milliseconds. In GDi systems, the sensor supports typical operating pressures between 100 and 500 bar while maintaining a consistent signal output.
