O2 sensor p073 / p078

[rik98svt]

So I got this both check engine code P173 (o2 sensor mixture too rich) and P178 (oxygen sensor) . How can I know wich one of the four sensor is defect??? Does an O2 sensor can reduce enough the power of the engine to be owned by a tiburon??? Damn it suck!!!!! Does it can increase considerably gas consumption with the both check engine I got???


Help me please cause i'm tired to get owned or just tie by some stock 4 cyl...

You have to post the correct codes. One alphabet and 4 numbers (ex. P0172 rich mixture Bank 2). Test the sensor.

When your CEL gets lighted up for the O2 sensor, the PCM tells the car to go on a limp mode. That is probably why it appears that the power has decreased and also why the gas consumption is up.
