For example, you can see what’s involved if you need to replace the windshield wiper motor on your vehicle or learn how to flush your car’s air conditioning system. It can also help you decipher specific diagnostic trouble codes (DTCs) such as P0133, an indicator that your oxygen sensor is having a problem, or P2135, which means there’s an error with your throttle control systems.
