this should help

If the car is not having any run issue I would definitely check the oil level. The code translates p1259 as VTEC System Malfunction. I would also ask if you have changed the oil recently. Typically running 10/40 rather than 5/30 in these motors can cause this code to be generated.

Code 1259 is vtec system malfunction, in other words, it's a variable valve timing and lift electronic control. It's honda's system used to control the rate of engine valves to open and close. Need to take it to a shop or dealer to have that checked out.

P1259 is a code for vtec malfunction usually cause by a bad vtec solenoid, vtec pressure sensor, low oil level, bad connection. Was oil change done? May want to check the oil level. P1166 is a code for a primary o2 sensor 1.

dealer only diagnostics,this vehicle uses encrypted software and evan if you get it too read it will show the wrong codes for the faults.
