Walker 254-1023 Fuel Tank Pressure Sensor

Walker Fuel Tank Pressure Sensor

Walker 254-1023 is a Sensor Only fuel tank pressure sensor built for accurate EVAP system pressure and vacuum monitoring. It is a direct OE-style replacement for the factory sensor used on 2017-2018 Mercedes-Benz CLA250 applications, with a 3-terminal blade pin design and oblong female connector for proper harness connection.

Walker Products Sensor Only components are focused on the sensor itself, making this part line a straightforward choice when replacing a failed pressure sensor in the fuel tank or EVAP system. The 254-1023 is calibrated to OE specifications for pressure range, electrical output, and response accuracy.

Key Features

• Fuel tank pressure sensor for EVAP system monitoring
• Fits 2017-2018 Mercedes-Benz CLA250, N/A
• Walker 254-1023 OE replacement part number
• 3-terminal blade pin design
• Oblong female connector with male terminals
• Built with fuel- and vapor-resistant materials
• Sealed electronics for harsh fuel system environments

Detailed Description

This fuel tank pressure sensor measures pressure or vacuum inside the fuel tank and evaporative emissions system, then sends that data to the ECU for leak detection, purge flow control, and emissions monitoring. On Mercedes-Benz CLA250 models from 2017-2018, Walker 254-1023 restores the factory signal needed for accurate EVAP diagnostics and normal drivability. If you are searching for a 2017-2018 Mercedes-Benz CLA250 fuel tank pressure sensor replacement, this part is built for the original mounting location and wiring interface.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Issues It Can Help Address

• Check engine light related to EVAP system faults
• Diagnostic trouble codes such as P0450, P0451, P0452, or P0453
• Incorrect fuel tank pressure readings
• Failed emissions inspection due to EVAP monitoring errors
• Drivability concerns tied to inaccurate purge or leak detection data

Installation Notes and Tips

Install Walker 254-1023 in the factory sensor location on the fuel system or EVAP assembly and connect it to the original wiring harness. Verify connector shape, terminal count, and terminal gender before installation to confirm proper fitment on your Mercedes-Benz CLA250. Clear stored fault codes after replacement and confirm the EVAP monitor completes its diagnostic cycle.

Quality Assurance

Walker fuel tank pressure sensors are engineered as OE replacement components and calibrated to meet factory pressure range, output, and response requirements. The sealed construction and fuel-resistant materials are selected for long-term service in fuel and vapor exposure environments.
