    Default Trouble Code 0452

    Does anyone have an idea of what to look for?

    The "generic" code says Evaporative Emission Control System - Pressure Sensor Low Input

    That means nuthin to me ...

    Any ideas what I should look for? Is this a big deal?

    I looked at an OBD II site, that code appears to relate to fuel pump issues. Here's a link to the site

    You tank has a pressure sensor so the PCM knows when to vent the hydrocarbons. Also the sensor is used to test the tank for any leakage. The testing is often done when the truck is shut off by the way. Common causes are a loose gas cap, bad gas cap, loose hoses, leaks of any kind. If the PCM detects a low input reading from the sensor it sets this code.
