Suzuki SX4. Engine light.

Asked by Sep 12, 2014 at 04:44 PM about the 2009 Suzuki SX4 Base

Question type: Maintenance & Repair

I have a 2009 Suzuki SX4 hatchback. The check engine light came on. Garage said it is
the catalytic converter. After a few days of driving, the light went out. Should I have
someone else check it. Wouldn't the light stay on unless it is something like the gas  cap?
It will cost a lot of money if it is the converter so I want to be sure.  Thanks for any help.

Have a local auto parts store scan the car and post the code or codes back here.

I had the same problem ... my garage scanned it and it came up as P0420, which is catalyst system efficiency below threshold bank 1.

Change air filter! Cheapest way and solving problem! Subi
