Welcome to the PT DIY Technical Information service.

If you're a Pit Pass subscriber click here, otherwise please continue reading below.

If you have a PT related question and or are experiencing a drivability issue perhaps we can help. Our Technical Library contains more than 1,800 questions and answers submitted by owners since November 2000.

1. If you have a PT related question please visit the Technical Library and select the appropriate subsection to research your question.

2. If you have a drivability issue and the engine light is NOT lit you may want to begin your research in the Technical Library, OEM Engine Performance subsection.

3. If you have a drivability issue and the engine light IS lit your vehicles' main computer (PCM) has sensed a Diagnostic Trouble Code and recorded it into memory. Once you identify the DTC it may provide you with a starting point to troubleshoot the issue. Many DTC's can only be identified through the use of a professional electronic instrument called a scan tool however a handful of commonplace fault codes can be identified using the vehicle diagnostic self test feature which any owner can access. (Don't forget to write the codes down while running the tests.)

3A. Once you have obtained the results of the self tests visit the Technical Library, Electronic Control Modules subsection to research the fault code. Please keep in mind that Diagnostic Trouble Codes are the result of a system or circuit failure, but do not directly identify the failed component or components. Therefore, in many instances note that we list multiple possible causes for each DTC. Each possible cause must be tested and eliminated in order isolate the faulty component or issue. Complete step-by-step diagnostics for each DTC are available through the Pit area on the site.

If the DTC is not listed in the Technical Library or you can't find an answer to your question there consider utilizing one of the following resources:
  • Owner manual. If you don't have an owner manual you can download one here.

  • Local dealer or repair shop.

  • Local auto parts retailer. (Some retailers are equipped with scan tools to check for DTC's.)

  • If you are a DIY'er and wish to handle the repair on your own, OE service manuals, and body, chassis, powertrain and transaxle step-by-step diagnostic manuals are available through the subscriber based Pit area on the site, which you can read about here.
