    check engine light is on 2005 chev equinox

    I recently had my plugs wires and throttle body cleaned for prev maintance purposes....now my check engine light is on...I work for a ford dealership..who did the work...they put it on the computer and it show exhaust issue and they said it needs a converter but I am just wondering if it i possible it could be a o2 sensor? I ? this because they told me I need a steering gear....ugh not...any help would be great.....

    If the light was not on before the maintenance work, it needs to be cleared to see if it comes back on. Yes, it could be a sensor. If the vehicle had been misfiring for a long period of time, or misfiring heavily for a short period of time it could have damaged the converter, which would then need replacement.

    places like autozone and advance auto will scan your truck and tell you what the code means for free.

    Parts store scans don't tell you any more than the one you have. The only way to figure out what a particular code means is to work your way through the trouble shooting tree for that code. Having said that, if the code they pulled is for low convertor efficiency and you don't have any indications of a plugged convertor a safe thing to try is replacing the downstream O2.
