How to fix the code P0453 on my 2001 Chevrolet Astro Van 4.3L V6?

Answer 1

Hi there,

This code is for the evap pressure sensor so this can be caused by a few things. Most often the cause is a leak in the vent control system or one of the lines leaking. You can smoke test the evap system and find the leak and usually solve this code. If you test and no leaks, then replacing the sensor is the next step.
