Having a basic understanding of DTCs can be helpful for drivers and fleet managers. Read on to learn more about DTCs, how they work, and how you can read them.

Identifying a DTC code is easier than you might think, and there are a few steps you can take to learn how to read this information. First, you must understand how a DTC code is interpreted. Generally, there are five distinct characters in the code, with the third character being a digit ranging from 1 to 8. The fourth and fifth characters are two-digit numbers between 0 and 99, and are called fault indexes. These fault indexes identify the issue specific to your vehicle. Thankfully, there are some tools available online that make reading and understanding a DTC code much easier. Identifying a specific fault index using the DTC code of your vehicle can help you diagnose problems that occur before your vehicle experiences a complete breakdown. These codes are not always accurate, though; a PX code will only indicate that a cylinder is misfiring.
