Fuel Tank Pressure Sensor Overview

Standard Ignition AS506 is a direct-fit fuel tank pressure sensor for vapor and vent pressure monitoring in select GM applications. It uses a female plug-in connector with 3 male blade terminals for straightforward OE-style replacement on vehicles such as the Chevrolet Silverado 1500, Chevrolet Avalanche, and Chevrolet Impala.

Key Features

  • Direct-fit OE replacement for fuel vapor and vent pressure sensing
  • Female connector with plug-in design for factory-style connection
  • 3-terminal male blade configuration
  • Built with high-quality materials for use in demanding underbody and fuel system environments

  • Standard Ignition AS506 for select Chevrolet, GMC, Buick, and Pontiac models

Detailed Description

The Standard Ignition AS506 fuel tank pressure sensor is built to replace the original sensor used to monitor fuel vapor and vent pressure in the evaporative emissions system. This part supports accurate pressure feedback to the vehicle control system, helping maintain proper EVAP operation on applications including the 2005-2007 Chevrolet Silverado 1500, 2004-2006 Chevrolet Avalanche 1500, 2006-2007 Chevrolet Impala, and 2007-2008 Chevrolet Express 1500. It also cross-references Dayco 72759 for the same application. Standard Ignition AS506 is a practical OE-style solution for drivers and technicians servicing GM fuel system sensor faults.

What It Helps Fix

  • EVAP system pressure sensor fault codes
  • Check engine lights related to fuel vapor or vent pressure readings
  • Hard-to-diagnose evaporative emissions monitoring issues
  • Incorrect fuel tank pressure signal output
  • Inspection failures tied to emissions system faults

Installation Notes and Tips

Verify connector style, terminal count, and vehicle application before installation. This sensor uses a female connector, plug-in design, and 3 male blade terminals, so matching the original electrical interface is important for proper fitment. Confirm the vehicle’s exact year and model, especially on GM platforms with overlapping service parts such as the Chevrolet Silverado 1500 Classic and Chevrolet Uplander.
