Well it looks like your vehicle has a few problems. Nine fault codes which all relate to engine controls.
P0102 - Mass Airflow Circuit - Low Voltage Input
P0134 - Oxygen Sensor Circuit - No Activity Detected (Bank 1 Sensor 1)
P0135 - Oxygen sensor - Heater circuit malfunction (Bank 1 Sensor 1)
P0140 - Oxygen Sensor Circuit - No Activity Detected (Bank 1 Sensor 2)
P0141 - Oxygen sensor - Heater circuit malfunction (Bank 1 Sensor 2)
P1421 - Secondary Air Injection Valve - Short To Ground
P1425 - Tank Ventilation Valve - Short To Ground
P1451 - Secondary Air injection Circuit - Short to Ground
P1472 - EVAP Control System LDP Circuit - Short To Ground
From all of these I would start by checking all of the fuses as a short to ground will usually cause a few to blow. Then check the harness for damage from exhaust heat or abrasion. The 4 EVAP related codes at the bottom can be a variety of things. Most of which you need a dealer level scan tool to test and verify operation.
It is not really bad, just an annoyance.
