Engine codes, DTC codes and OBD codes – what are they and how do I read them?[/caption]
As a car owner, it’s important to be aware of the various engine codes that may come up when you’re driving. These codes can indicate a variety of issues with your vehicle, and understanding what they mean is crucial to maintaining your car’s health. In this blog post, we’ll explore the different types of engine codes – DTC codes, OBD codes and more – and explain how you can read them. By the end of this post, you should have a good understanding of what these codes mean and how to interpret them.
What are engine codes?[/caption]
Engine codes, DTC codes and OBD codes are all terms used to describe the same thing – a trouble code stored in your vehicle’s computer. These codes are generic; they apply to all makes and models of vehicles.
When something goes wrong with your car, the computer stores a code that can be read with a scanner. The code will tell you what component or system is not working properly. You can then take steps to fix the problem, or take your car to a mechanic for repair.
DTC stands for Diagnostic Trouble Code, and OBD stands for On-Board Diagnostics. Both refer to the same thing – the trouble codes stored in your car’s computer.
If you have a check engine light on, or if your car is behaving strangely, it’s a good idea to read the codes and see what’s going on. A scanner is the best way to do this, but you can also take your car to a mechanic who can read the codes for you.
OBD, or On-Board Diagnostics, is a system that monitors your vehicle’s engine and emissions control devices. The system turns on a warning light on your dashboard if it detects a problem.
To read engine codes, you’ll need an OBD reader. You can buy one at any auto parts store, or borrow one from a friend. Once you have the reader, connect it to your car’s OBD port. The port is usually located under the dash, near the steering column.
Once the reader is connected, turn on your ignition but don’t start the engine. The reader will display any codes that are stored in your car’s computer. Write down the codes and look them up in a code book to find out what they mean.

DTC codes are diagnostic trouble codes that are used by automotive technicians to diagnose and repair issues with a vehicle. These codes are stored in the vehicle’s computer system and can be accessed using a diagnostic tool. DTC codes can help identify the root cause of a problem and help technicians resolve it quickly and efficiently.
These codes can be read by a diagnostic tool, which can be purchased at most auto parts stores.
To read DTC codes, you will need to connect the diagnostic tool to the OBD-II port of your vehicle. Once the connection is made, the tool will access the onboard computer and retrieve the codes.
Thecodes will be displayed on the screen of the diagnostic tool. They will be listed as either P-codes or C-codes. P-codes are powertrain related codes, while C-codes are chassis related codes.
What are OBD codes?[/caption]
When something goes wrong with your engine, the computer will store a code in the memory. This code can be read with a code reader or scanner. The code will tell you what is wrong with the engine.
If your car is having issues, you may need to read the OBD codes to determine what the problem is. Here’s how:
If you’re a car owner, it’s important to understand what engine codes, DTC codes and OBD codes are and how to read them. These codes can provide valuable information about your car’s engine and can help you troubleshoot any problems that you may be having. While they may seem daunting at first, with a little practice, you’ll be able to read these codes like a pro.
Start by reviewing the codes below:
The P0145 trouble code is a diagnostic trouble code (DTC) that indicates an issue with the oxygen sensor circuit, specifically a slow response from the downstream oxygen sensor located in Bank 1, Sensor 3. This code is part of the On-Board Diagnostics II (OBD-II) system, which is standard in vehicles manufactured since 1996. When the … Read more
The P1074 trouble code is part of the On-Board Diagnostics II (OBD-II) system and is associated with issues in the vehicle’s fuel and air metering system. Specifically, this code indicates that the Engine Control Module (ECM) has detected a problem with the fuel injector circuit, particularly related to cylinder contribution or balance faults. This can … Read more
The P1184 trouble code is a diagnostic trouble code (DTC) that indicates an issue with the Engine Oil Temperature (EOT) sensor. Specifically, it signifies that the EOT sensor is reporting a temperature outside the expected range during a self-test. This could potentially lead to performance issues in the engine, as the oil temperature is crucial … Read more
The P1389 trouble code is a diagnostic trouble code (DTC) that indicates a malfunction in the vehicle’s powertrain system, specifically related to the Auto Shutdown (ASD) relay. This code is triggered when the Powertrain Control Module (PCM) does not detect voltage from the ASD relay when it is supposed to be energized. The ASD relay … Read more
The P2102 trouble code is a diagnostic trouble code (DTC) that indicates an issue with the throttle actuator control motor circuit. Specifically, it signifies that the powertrain control module (PCM) has detected a low voltage condition in the throttle actuator “A” control motor circuit. This code is prevalent in vehicles equipped with electronic throttle control … Read more
The P0346 code is a diagnostic trouble code (DTC) that indicates a problem with the Camshaft Position Sensor ‘A’ Circuit Range/Performance on Bank 2 of the engine. This code is typically set when the engine control module (ECM) or powertrain control module (PCM) detects an issue with the signal from the camshaft position sensor, which … Read more
