What is the OBD code for an engine?
P0420, P0430: Any vehicle with OBD II standards will feature an oxygen (O2) sensor closer to the catalytic converter. The converter can be fouled due to an engine that’s burning oil or has an internal coolant leak. It’s also common for fuel to damage catalytic converters.
What does the 0 in the engine code mean?
U denotes network communications (controller area network wiring and modules, post-2006 vehicles) Of these, an engine code that has a 0 in its second digit is one that applies across the board, to all vehicles and manufacturers.
What does the code p0455 mean on a car engine?
This EVAP system consists of vent hoses and a charcoal canister that captures fuel vapors, as well as a valve that purges the fumes back into the engine when it’s running. The P0455 code, for instance, indicates a loose or missing gas cap, while P0442 denotes a cracked or loose vapor hose or leak in the EVAP canister.
Why do I have a code on my engine?

Where can I get an engine code reading?
You can get a reading done at any Advance store. This saves a lot of time and guesswork — in years past, a tech (or shade-tree mechanic) would have to rely on intuition and educated guesses to troubleshoot a vehicle’s problems, which would sometimes lead to a dead end. The engine code, however, does not tell the tech which part to replace.
