  • Fuel tank pressure sensor faults tied to the module assembly

Installation Notes and Tips

Verify the vehicle application before installation: Fits 2014-2020 Chevrolet Impala, N/A. Confirm connector style, inlet and outlet orientation, and tank configuration against the original assembly before removal.
