NISSAN 25070-CD00A Engine Oil Pressure Sensor

The genuine NISSAN 25070-CD00A engine oil pressure sensor is a critical electromechanical component responsible for continuously monitoring the oil pressure within the engine lubrication system. The sensor transmits precise measurement data to the vehicle's engine control unit (ECU) and instrument cluster gauge, ensuring proper engine lubrication and preventing severe mechanical damage.

Technical Features and Operating Principle

This premium quality OEM sensor utilizes advanced sensing technology designed to withstand high temperatures and vibration within the engine block. By transmitting accurate pressure values, the system can instantly detect critical drops in oil pressure.

• Connector Type: 3-pin electrical connector for stable and interference-free signal transmission.
• Thread Size: Standard tapered thread for leak-free and accurate installation on the engine block.
• Material Quality: Highly heat- and corrosion-resistant metal housing with a robust plastic connector body, resistant to engine oil and environmental exposure.
• Measuring Range: Optimally calibrated for precise tracking of factory engine oil pressure parameters.

Common Symptoms of Failure

The oil pressure sensor is subject to natural wear, thermal cycling, and internal diaphragm aging. Common signs of failure include:

• The dashboard oil pressure gauge displays unstable or erratic readings (reading excessively low or pegged at maximum).
• The red oil pressure warning light on the instrument cluster illuminates or flashes intermittently without cause.
• Oil leakage observed at the sensor's electrical connector (caused by internal diaphragm failure).
• Diagnostic Trouble Codes (DTCs) stored in the engine control unit relating to the oil pressure circuit.

To ensure safe engine operation, a failed sensor should be replaced promptly with an original OEM part, preventing false diagnostics and catastrophic damage from potential lubrication issues.
