2000 chevy blazer 4.3. The service engine light is on and I got four codes PO135, PO146, PO147, PO155. What do these codes mean and what do I need to do to get the service light to turn off so I can inspect it?

Those are all O2 sensor circuits. See if the wires leading to them have been burnt from touching the exaust pipes.

Is the one of the 02 sensor circuits located behind the catalytic converter and is the other one by the exhaust manifold?
