Usually when the engine light comes on, it is due to a bad sensor or circuit. Anything electrical or electronical can set it off. The only real way to tell why it is on, is to have a diagnostic scanner put on and have engine codes read. Many part storew will do it for free. It will pinpoint exact problem location area

My 2002 Volkswagen jetta lights on for traction control and ERP light. Car has no power.

Hi there?
The traction system is linked to the engine managment, if there a fault in the traction system it can reduce the engine power output. You need to scan the traction control system to see what fault code comes up.

P0420 code was told to me by shop when check engine light came on. What is an easy solution to this before taking to shop to be overcharge for something simple. 2002 jetta 2.0 gls 5spd

Sorry, but i don't believe there is an easy, cheap fix. p0420 is a catalytic converter ineffiency code - meaning the cat isn't doing what it is supposed to do and needs to be replaced. google the federal warranty for 2002 to see if it is still covered. i think it's 8years/80,000 miles.

I have a 2002 volkswagon passat all wheel drive, 6 cylinder engine. The cost of a catalytic converters are very high. I need it for both the right and left front. I bought the car used. Is it a government thing that because it is a emission thing and my car is a 2002 do I have to pay to have this fixed?
