• Rough running caused by inaccurate pressure feedback
• Fuel, timing, exhaust, or cooling control concerns tied to sensor input

Installation Notes and Tips

Verify connector style, terminal count, and vehicle application before installation. This sensor uses a female connector with 3 blade terminals and male terminals, so matching the electrical interface is important for proper fitment. Confirm the vehicle by year, make, and model, especially on Mercedes-Benz CLA250, CLS550, E550, and S550 applications.

For best results, inspect the connector and wiring harness for corrosion, bent terminals, or damaged locking features before installing the new sensor. Clear any stored diagnostic trouble codes after replacement and recheck system operation.

Quality Assurance

Global Parts engine management sensors are built to meet OE specifications and are intended as direct replacement components for accurate ECM communication. The 1811271 fuel injection pressure sensor is designed for consistent signal output in supported Mercedes-Benz applications.
