It looks like you have two bad O2 sensors an a bad mass air flow sensor . Is your vehicle a 4 cylinder or 6 0r 8 cylinder ? Bank 1 sensor 1 an bank 1 sensor 2 heater circuits . plus you have a EVAP. emission purge control circuit problem ! I would go on you tube an enter your trouble codes to see videos on testing

P0134 - O2 Sensor Circuit No Activity Detected Sensor 1 Bank 1
P0135 - O2 Sensor Heater Circuit Malfunction Bank 1 Sensor 1
P0053 - O2 Heater Resistance Bank 1 Sensor 1
P0030 - O2 Heater Control Circuit Bank 1 Sensor 1
You need to replace the O2 Sensor Bank 1 Sensor 1
Carquest can help you get the correct part and help you locate it.

P0135 comes up, o2 sensor bank 1 sensor 1
P0325 refers to a knock sensor circuit malfunction
P1705 Direct Clutch Speed Circuit Fault

The fault code P0135 means O2 Sensor Heater Circuit (Bank 1 Sensor 1)
The code P0141 means O2 Sensor Heater Circuit (Bank 1 Sensor 2)

Launch X431 Connector

You have a bad O2 sensor on the left side of the engine (Bank 1)

P0134....O2 Sensor Circuit No Activity Detected (Bank 1 Sensor 1)

P0135....O2 Sensor Heater Circuit (Bank 1 Sensor 1) heater in the O2 sensor has packed up first sensor before the cat

p0135 indicates bank 1 sensor 1 which is before the cat.

the O2 sensor for bank one sensor one is located between the catalytic converter and the engine in the exhaust head pipe. see photo of your engine cylinder layout, the sensor u want to replace is the one at the cylinder #1 bank on right.
