These OBDII Check Engine Light Trouble Code walkthroughs will help you clear your check engine light issues and any OBDII or smog related problems you may have. We’ve broken out our guides in easy to read format, allowing you to pick the OBDII check engine trouble code help you need.
OBD is the On-Board Diagnostics of your vehicle’s ECU or PCM, capable of testing many different facets of your vehicle and engine to ensure maximum performance and efficiency. These set of self diagnostic tests can test everything from your powertrain to your chassis or sensor issues.
The Engine Control Module (ECM) or Powertrain Control Module (PCM) monitors the engine for conditions that can cause an issue with your engine or vehicle. If the ECM or PCM detects a potential problem, a warning light called a “malfunction indicator light” (MIL) on the dashboard is illuminated to alert the driver of a problem. This light is usually identified by the words “Check Engine,” “Service Engine Soon,” or the word “Check” along with an engine symbol.
