Engine check light came on few days ago and i used a diagnosis machine which picked p1653 scv motor circuit malfanction.
P1653 SCV Circuit Malfunction
This could be caused by the oil control valve, low oil level, infrequent oil changes, a fault in the wiring to the valve or a bad PCM. What is odd is that the code is not listed in my information database.

When you have P0440, P0441 and P0446, it is a very good bet that the fuel cap was loose, or the fuel cap rubber seal is compromised. You will get all three of those codes every time that the cap is loose. Always make sure that the fuel cap is as tight as you can get it after you refuel.

clean up all ground wires but you may need both of those items

Hi
Could mean there is one fault causing many faults, example, Air mass sensor, this can cause rough idle and over fuelling so the code reader will just send it back with undefined as there are to many faults to identify as the cause.
Most likely it will be a air fault so check the air sensor first, try cleaning it with carb cleaner, sometimes works. If not get back to me could be 2 other things. although the car will not drive very well if it is any of the other 2.

Dan

Your EVAP purge valve may be faulty. Also, check the vaccum lines attached to the valve for any signs of wear and tear. Should be located next to the coolant tank.
