A high-quality engine oil pressure sensor, designed for JCB, Hitachi, Sany, and Sumitomo machines equipped with ISUZU engines (e.g., 4BG1, 6BG1). It is a key component of the lubrication system, responsible for continuously monitoring oil pressure and transmitting this information to the control computer and cab gauges. The precise operation of the sensor is the first line of defense against engine seizure, allowing for an immediate response in case of a pressure drop.
GX-AFTER is the smart choice for your machine. We provide high-class replacement parts that combine excellent quality with an attractive price. Each part is carefully verified to ensure full compatibility and reliability you can depend on.

The list above is for reference. The key is to match the sensor to your engine model.
Before replacing any electrical components, you must disconnect the negative (-) terminal from the battery. Ensure the engine is cool to avoid burns from hot oil.
The oil pressure sensor is the most important guardian of your engine's life. Its failure can lead to a lack of warning about low pressure, resulting in engine seizure, or to false alarms that immobilize the machine.
A faulty sensor is a ticking time bomb under your machine's hood.
The cost of a new sensor is negligible compared to the overhaul of a seized engine. Don't risk the most expensive failure – order a new, reliable GX-AFTER sensor and be confident you know your engine's condition.

Not necessarily. It is a warning signal that must not be ignored. First, **shut down the engine immediately** and check the oil level. Other causes include a faulty oil pump, a clogged oil filter, or worn bearings. Before deciding to replace the sensor, the oil pressure should be measured with a mechanical gauge.
2. How does an oil pressure sensor work?It is a transducer that converts the physical pressure of the oil into an electrical signal. Inside is a diaphragm that flexes under pressure, changing the resistance or voltage in the circuit, which is read by the machine's computer.
3. Where is this sensor typically located on an Isuzu engine?The oil pressure sensor is usually screwed into the engine block, near the oil filter or in the main oil gallery. It is a small component with a single electrical connector.
