How do I manually check my engine code?
At Kevin's Autos, we understand that seeing the "Check Engine" light on your dashboard can be stressful. However, you don't always need to rush to a mechanic to figure out what's wrong. With a little know-how, you can manually check your engine code and get a better idea of what might be causing the issue. Here's a step-by-step guide to help you through the process.
What Are Engine Codes?
Engine codes, also known as diagnostic trouble codes (DTCs), are alphanumeric codes generated by your car's onboard diagnostic (OBD) system. These codes help identify specific issues with your vehicle's engine, transmission, or other systems. By retrieving these codes, you can pinpoint the problem and decide on the next steps for repair.
Steps to Manually Check Your Engine Code
While modern vehicles often require an OBD-II scanner to read engine codes, some older cars allow you to retrieve codes manually. Follow these steps to check your engine code:
- Step 1: Turn Off Your Vehicle
Ensure your car is parked on a flat surface and the engine is turned off. Safety first!
- Step 2: Locate the Diagnostic Connector
Find the OBD port, which is usually located under the dashboard on the driver’s side. In older vehicles, this might be a different type of diagnostic connector.
- Step 3: Use the Key Cycle Method (For Older Cars)
For vehicles without an OBD-II scanner, you can use the key cycle method. Insert your key into the ignition and turn it to the "On" position (without starting the engine). Repeat this process three times, ending in the "On" position.
- Step 4: Observe the Check Engine Light
After cycling the key, watch the "Check Engine" light. It will begin to flash in a sequence. Count the flashes to determine the code. For example, two flashes followed by three flashes would indicate code 23.
- Step 5: Decode the Engine Code
Refer to your vehicle's service manual or search online for the meaning of the code. This will give you insight into the specific issue your car is experiencing.
When to Use an OBD-II Scanner
For vehicles manufactured after 1996, an OBD-II scanner is the most reliable way to retrieve engine codes. These scanners are affordable and easy to use. Simply plug the scanner into the OBD port, turn on your car, and follow the scanner's instructions to read the codes.

Frequently Asked Questions
How do I find out what my engine code is?
