Diagnostic trouble code P04B7 indicates: Fuel Fill Door Position Sensor/Switch Circuit Intermittent/Erratic. It was set by your vehicle's onboard diagnostics system and will typically keep the check engine light on until it's addressed.
Upload your ECU file and DTC Doctor will detect this code (and any others) automatically, then remove it for good — no dealer visit, no guesswork.
