Does Chevy Send Engine Codes to the Car?

Yes, Chevy sends engine codes to the car.

Engine codes are diagnostic trouble codes (DTCs) that are stored in the car’s computer. These codes are used to help identify the source of a problem with the engine. When a problem is detected, the computer will store a code that corresponds to the problem. This code can then be retrieved by a mechanic using a scan tool.

There are many different types of engine codes. Some of the most common codes include:

P0101 – Mass air flow sensor (MAF) circuit range/performance problem
P0102 – MAF sensor circuit low input
P0103 – MAF sensor circuit high input
P0113 – Intake air temperature (IAT) sensor circuit high input
P0118 – Engine coolant temperature (ECT) sensor circuit high input

If you see an engine code on your car’s dashboard, it is important to have the code diagnosed by a mechanic as soon as possible. Ignoring an engine code can lead to further damage to the engine.

How to Retrieve Engine Codes from a Chevy

There are two ways to retrieve engine codes from a Chevy:

Use a scan tool. A scan tool is a device that can be plugged into the car’s diagnostic port. The scan tool will communicate with the car’s computer and retrieve any stored engine codes.
Use the car’s built-in diagnostic system. Some Chevy models have a built-in diagnostic system that can be used to retrieve engine codes. To use the built-in diagnostic system, follow these steps:

Turn the ignition key to the “On” position, but do not start the engine.
Press and hold the “ODO” button on the instrument cluster for two seconds.
The odometer will display the number of stored engine codes.
Press the “ODO” button again to scroll through the engine codes.
