Diagnostic trouble code P0EC7 indicates: A/C Power Supply Relay Control Circuit Low. 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.
