Decoding the Mystery: What Are Pending Codes?

Pending codes are diagnostic trouble codes (DTCs) that haven’t yet triggered the check engine light. They indicate a potential issue that the car’s computer has detected but hasn’t yet confirmed. Checking for these codes when buying a used car can reveal underlying problems that the seller might not even be aware of. This is especially important when buying used, as a clean check engine light doesn’t always mean a healthy car.

Why Are Pending Codes Important When Buying a Used Car?

Pending codes provide a glimpse into potential future problems. They can be a valuable bargaining chip during negotiations or a warning sign to walk away from a potentially troublesome vehicle. Think of them as an early warning system, giving you a heads-up before a problem becomes serious.

“Pending codes are often overlooked, but they can be a crucial indicator of potential issues,” says automotive expert, Michael Stevens. “Savvy buyers use this information to their advantage during negotiations.”

How to Check for Pending Codes

Checking for pending codes is a simple process. You’ll need an OBD2 scanner, which you can easily purchase online or at most auto parts stores. You can even use a phone obd2 scanner for added convenience. Simply plug the scanner into the OBD2 port, usually located under the dashboard on the driver’s side, and turn on the ignition (but don’t start the engine). The scanner will then display any stored and pending codes. Refer to the scanner’s manual for specific instructions, as models may vary. Some advanced scanners even provide detailed descriptions of the codes and potential causes.

What Do the Codes Mean?

Understanding the meaning of the codes is crucial. While the scanner might provide a brief description, further research is often necessary. You can find a wealth of information online, or consult a trusted mechanic. Don’t be afraid to ask the seller about any pending codes you find. Their response can provide further insight into the car’s history and their honesty. You might even consider taking the car to a mechanic for a pre-purchase inspection for a professional opinion.

Common Pending Codes and Their Implications

Some common pending codes relate to emissions, misfires, and sensor issues. For instance, a pending code related to the oxygen sensor could indicate a future problem with the catalytic converter. A pending misfire code might point to a failing ignition coil. Understanding the implications of each code is key to making an informed decision.

Can Pending Codes Be Cleared?

Yes, pending codes can be cleared, but this doesn’t fix the underlying problem. If you notice a seller has recently cleared codes, be extra cautious. It’s a good idea to drive the car for a while and then rescan to see if any codes reappear.

“Clearing codes is a common tactic used to mask potential problems,” cautions Sarah Chen, a certified mechanic. “A rescan after a test drive is always recommended.”
