Detailed Description

This fuel tank pressure sensor monitors pressure changes in the fuel tank and sends that information to the vehicle’s control system for evaporative emissions diagnostics. Standard Ignition AS502 is an OE-style replacement built to match the connector, terminal, and mounting configuration used on supported Hyundai and Kia models, including Santa Fe Sport, Santa Fe, Veracruz, Sonata, Sorento, Borrego, Optima, Rondo, and Amanti applications.

Common Issues It Can Address

• EVAP system fault codes related to fuel tank pressure readings
• Check engine light triggered by pressure sensor signal errors
• Hard-to-diagnose evaporative emissions monitor failures
• Incorrect fuel tank pressure data reported to the control module
• Replacement of a damaged or corroded sensor connector interface

Installation Notes and Tips

Verify connector shape, terminal count, and mounting style before installation. This part uses a female oval plug-in connector with 3 male blade terminals and does not include mounting hardware, O-rings, or a wiring harness.
