We're Interested in car to buy, but the owner says its shooting codes P0300, P0301 and P0302. What does those codes mean?

Answers from the Automotive Experts

Amanda J. Pierce, MBA Rudy, Those PO codes are indicative of a misfire that you may have across the spark plugs, or coil packs.

Gelina Aquilina, Service Advisor / Mechanic at They are misfire codes; you should never purchase a vehicle with a check engine light on becuase that's an automatic failed smog. The seller is responsible for smog prior to the sale of a vehicle. Sounds like the car needs a full tune up prior to it's sale!

Helaine Kurot, Owner/Technician at 360 Automotive Those codes are misfire codes. The P0300 is a random misfire (could be any cylinder), the P0301 is a cylinder 1 misfire, and the P0302 is a cylinder 2 misfire. Usually on this type of vehicle it is just a matter of replacing the spark plugs and/or wires and is a relatively simple repair. It is possible there are other issues that could be causing these codes. If you are considering purchasing this vehicle, I would have a technician look at it before you buy it. The check engine light being on is already warning you that this car has issues. They may be very minor issues and the vehicle may just be in need of some routine maintenance. But you will be much better off having it looked at and making sure that there are no potentially larger issues coming much sooner than later. Given the codes that are present, I would request that the technician check cylinder compression as well as the condition of the timing belt. The shop may charge a little more for theses inspections, but you will be much better off knowing if this engine has existing internal issues before you make this purchase.
