Chrysler's 2003 Town and Country is a large-sized minivan with front-wheel drive. The 3.8-liter is the standard engine size, with a 20-gallon tank that gets 23 miles to the gallon on the highway. The "Check Engine" signal lights up in the dash when the Chrysler's computer recognizes a malfunction in the engine. A code reflecting that problem is stored for your retrieval, and the light flares up to let you know it's there.

[edit] Check Check Engine Light

  • Look under the driver's-side dash for the Assembly Line Diagnostic Link, or ALDL. This 12-to-16-port electrical device is the link to the stored trouble codes in your Chrysler's computer. Pop off the plastic cover to expose the ports.
  • Connect the scanner test lead to the ALDL. Turn the scanner on, then turn the ignition key to the "On" position without cranking the engine.
  • Read the questions that appear on the scanner's digital screen. Each question is a prompt for information about your vehicle's year, make and model. Answer each prompt.
  • Write down the "Check Engine" error codes as they appear on the screen. Each code has a meaning that points to a specific problem detected in the engine. Refer to your Town and Country owner's manual for the code meanings, or click the link in the Resource section for a comprehensive list of Chrysler error codes.
  • Address the root of the problem. Pull the codes again. Select the option to reset the computer's code system after the codes are displayed on the screen.

[edit] Tips & Warnings

  • The codes will reappear if the underlying cause of the issue hasn't been repaired.
  • Try holding down the odometer trip button down while turning the key to the "On" position if you don't have a scan device. The codes will read out on the digital odometer after every dash instrument is tested.
