FAQ

Q1: How do I confirm this sensor is compatible with my engine?
A1: The primary method is part number matching. Locate the sensor on your engine’s common rail pump or fuel metering unit and verify the stamped part number is 3949988. You can also cross-reference your engine’s service parts catalog using the OEM number provided.

Q2: What is the typical delivery time to my country?
A2: For most orders, processing and shipping take 3-7 days. Delivery time to destination depends on your location and chosen shipping method. We offer express options to major global hubs for faster receipt.

Q3: Is this sensor ready for installation, and what about calibration?
A3: Yes, the sensor is a direct replacement part and comes ready for installation. In most modern common rail systems, the Engine Control Unit (ECU) may automatically adapt to the new sensor. However, for optimal performance, it is recommended to clear any existing fault codes and, if specified by the manufacturer, perform a system calibration using professional diagnostic software after installation.
