Code 4 and engine lite on

If the check engine light is on there will be OBDII and manufacturer specific codes. These codes start with a letter and are followed by four numbers (P0304 for example). These codes can only be read by an OBDII code reader or a scan tool. These are the codes you need to get in order to start trouble shooting your vehicles problem.

Service engine lite on Can it be from low octane gas

It can also be called the " Check engine light ".
In order to turn off the "Check Engine Light", you or a trusted mechanic check the Onboard Diagnostics (OBDII) OBDII uses a "code reader" which plugs into your car (usually in the dashboard, or near the radio...) and that tells you what "malfunction" is setting your Check Engine Light off.
Basically, if there is a fault in any computer controlled system (fuel, ignition, SRS (airbag), emissions etc) the Electronic Control Unit (ECU) sends a code to the OBD unit... Then the code reader breaks down the fault, it's location and usually (with a good reference manual) you can remedy the problem (or at least narrow it down!)

Thank you Sir, Have a nice day.

Check engine light comes on

"po455 large leak" means that you are not maintaining positive pressure in your fuel system. Have a mechanic do a "smoke test" on the fuel system. Could be as simple as a loose gas cap...
