038 919 081P – Oil Pressure Sender (1 Pin)

Description

The 038919081P Pressure Sender is an OEM-quality single-pin sender designed to monitor real-time engine oil pressure. This 038919081P Pressure Sender transmits a continuous signal to both the instrument cluster gauge and the ECU, giving the driver and engine management system accurate oil pressure data. Consequently, it serves as a primary safeguard against undetected lubrication failure.

This unit is rated at 0.75–7.05 BAR and is identified by its gray housing color. Furthermore, some applications use two different oil pressure senders simultaneously, each monitoring a different pressure range. Therefore, always confirm your specific application and sender location before ordering to ensure the correct unit is installed.

Why the 038919081P Pressure Sender Matters

Accurate oil pressure monitoring is essential for protecting internal engine components from friction and heat. However, a faulty sender can transmit incorrect readings to the cluster gauge and ECU. Consequently, the engine management system may fail to detect a genuine low-pressure condition, leaving critical components unprotected.

Additionally, a defective sender can cause the oil pressure gauge to display a reading even when the engine is not running. Furthermore, incorrect pressure data can interfere with ECU-controlled functions that rely on oil pressure signals. Replacing a faulty 038919081P Pressure Sender restores accurate monitoring and supports reliable engine protection.

Signs of Failure

Use this simple diagnostic check and inspect for these symptoms:

• Quick Test: Turn the ignition on with the engine off. If an oil pressure reading appears on the gauge, the sender is defective and must be replaced.

• Oil pressure gauge reading fluctuates erratically during normal driving.

• Gauge reads zero at all times, even with the engine running.

• Oil pressure warning light stays on despite confirmed correct oil level.

• Intermittent oil pressure warnings with no mechanical cause identified.

• Oil seepage around the sender body or electrical connector.
