2008 Chevrolet Chevy Express G2500, Van Cargo, 6.6 6SECTION Introduction
WARNING: This page does not describe the selected car, but rather 26 other vehicles, including the 2003 Saturn LW300, 2003 Saturn LW200, 2003 Saturn L300, 2003 Saturn L200, and 2003 Saturn Ion 3. However, it is still accessible from the selected car via links, so may be relevant.
Sensor operating range information can help determine if a sensor is out of calibration. An out-of-calibration sensor may not set a trouble code, but it will cause driveability problems.
NOTE:
Unless stated otherwise in test procedure, perform all voltage tests with a Digital Volt-Ohmmeter (DVOM) with a minimum 10-megohm input impedance.

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
