Additionally, while an OBD code is not necessarily specific to a certain make or model of vehicle, the steps required to remedy it likely depend on the type of car, truck or SUV you drive. That is, you may see a certain code on an OBD-II system for your BMW, Chevrolet, Chrysler, Dodge, Ford, GMC, Jeep, Subaru, Toyota or another type of vehicle. The error detected may be dependent on what different makes of vehicles are capable of generating. On most vehicles nowadays, there are hundreds of possible DTCs a car can generate. For example, if your vehicle’s OBD detects a leak in the evaporative emission system, you may see a P0442 code.

Reading as a series of five letters and numbers, the DTC allows you to home in on the system that is not functioning properly.
If your vehicle has this system, you need an OBD-II diagnostic scanner to communicate with its OBD system. Since 1996, vehicles have an OBD-II diagnostic system. The OBD may alert you to problems with your vehicle’s engine, airbags, antilock brakes and other components.

Of course, if your vehicle’s computer produces one, you need to know what your trouble code means.īefore exploring what each code means and how to fix it, you should understand two important concepts. You can refer to our master list of DTCs to help you best understand your specific car problem based on your code.Modern vehicles have internal computers that not only control the overall performance of your car, truck or SUV, but they also alert you to a problem by generating trouble codes. In total, there are over 5000 generic and manufacturer exclusive OBD 2 troubleshooting codes that exist. These are numbered by “00”, “01”, “02” and so on. The fourth and fifth characters in the code represent a specific description of the problem with the part and system in question. This list of characters include 1 (fuel and air metering), 2 (fuel and air injector circuit), 3 (ignition), 4 (auxiliary emission control), 5 (vehicle speed and idle control systems), 7, 8 or 9 (transmission) and A, B or C (hybrid propulsion). The third character can be one of many letters or numbers. 1 means it is a car manufacturer exclusive code. The second character either will be a 0 or 1. This character will help you determine which of the four main car’s parts is at fault. The first character will either be P (powertrain), B (body), C (chassis) or N (network). In order to prevent unpredictable and unexpected DTC codes, as well as ensure that you understand fully what could be wrong with your car as problems occur, purchase a good OBD 2 scanner that is programmed to help car owners and technicians better understand a car’s specific problem or problems.ĭTCs come in a string of five characters. You may even likely just need to fix or replace the wiring of the sensor alone in order for the problem to be solved.ĭTCs can also be activated by faults in the foreseeable future, giving you inaccurate codes for problems or notifying you of a problem that may not even exist with the car in the first place.įor instance, a muddled MAF sensor could lead the car’s system to believe that the car has fuel mixture problems, when in reality, the sensor is causing the car to mix fuel unevenly. A car’s parts or components should not be replaced without reference from its manual, even if you have a clear identification of the DTC and what it describes.įor instance, if a DTC notifies you of a sensor problem, the solution of that problem might not be to replace the sensor, but rather to replace another component that the sensor is affiliated with. The the best understanding of possible causes of problems with the car, refer to the car’s manual.
