po135 is o2 sencer on drivers side. will be the first one. po300 is random/multiple misfire.po404 is a egr code. po102 mass air flow circuit low input. po440 evap emission control system malfunction

code po122 is for your throttle position sensor. po155 is for your down stream o2 senor .po135 is for your bank 1 sensor 1 o2 sensor. po102 is for your maf sensor

P0102 is a MAF SENSOR CODE (MASS AIR FLOW)

there is an 23 step diagnostic procedure for this code

Mass or volume air flow circuit low voltage. mass air flow sensor could be going bad, or the wires are bad, damaged, disconnected. it could also mean your air filter is cloged
