9. Toyota fault codes

Toyota fault codes refer to error codes corresponding to fault conditions that occur in Toyota cars. For car mechanics and car owners, knowing and understanding fault codes is one of the important steps in solving car problems. This article will introduce the meaning of Toyota vehicle fault codes, the interpretation of common fault codes and the methods to solve the fault codes.

1. What are Toyota car fault codes?

In modern cars, the on-board computer system monitors and records the data of various sensors and the working status of the vehicle. When the system detects an abnormal condition, it generates a fault code indicating what type of malfunction occurred. A fault code is an identification code composed of a series of numbers and letters. Each code represents a specific fault condition.

2. Common Toyota fault codes and their interpretations

The following are some common Toyota fault codes and their meanings:
