Hello:)

First thing. There is no rear SAM for your car. All these items you listed involve the SAM module in the front (under the hood, at the driver's side, where the fuse panel is).

Glad that you could turn the key and start the car, but I think the problem is more than a battery, based on what you posted. If the EIS has 12.4 Volts with the key inserted, it should have enough...

Typically you get P0170/ P0173 codes for MAF, air/fuel related issues. These are due to O2 sensor output swings shifts (up and down for rich or lean fuel mixtures). You would not get a code from...

1) Just because you get an O2 sensor fault, this does not mean the O2 sensor is faulty. O2 sensors are messengers, they detect an abnormal condition, and report them, and people replace the O2...
