-P1607 is an ECU and TCU error also known as (PCM)
Replacement is a common fix but be aware that if your keys are not programmed for the car or you have bad connections at the battery it won't fix it.
-P0131 is a problem with your O2 sensor on bay 1 that signifies high oxygen content (too little fuel or too much o2) manifold leaks can be a cause.
-P1705 is a tire pressure sensor error. This is not a big issue in light of the other issues you are having at the moment.

DTC P0131 HO2S Circuit Low Voltage Sensor 1
The PCM supplies a bias voltage of about 450 mV between the HO2S signal and low circuits. When measured with a 10 megaohm DMM, this may display as low as 350 mV. The oxygen sensor varies the voltage within a range of about 1000 mV when the exhaust is rich, down through about 100 mV when exhaust is lean. The PCM constantly monitors the HO2S signal during closed loop operation and compensates for a rich or lean condition by decreasing or increasing injector pulse width as necessary. If the HO2S 1 voltage remains excessively low for an extended period of time, DTC P0131 will be set.
Do you have a advanced scan tool to check O2 sensor data ?
This video is on a honda but your's works the same Honda Civic P0131 02 Sensor Diagnosis
Error Code:P0130 Fault:
Oxygen Sensor (O2S) 1, Bank 1 - Circuit Malfunction Possible Cause:
Malfunction Indicator Lamp (MIL) Triggered on first occurrence.
-Wiring harness.
-Oxygen sensor (O2S).
-Engine control module (ECM).
Error Code:P0505 Fault:
Idle Speed Control (ISC) System - Malfunction Possible Cause:
-Wiring harness.
-Idle speed control (ISC) actuator/Idle air control valve (IAC) valve.
-Throttle motor.
-Throttle valve tight/sticking.
-Engine control module (ECM).
Error Code: P0100 Fault Location:
-Mass Air Flow (MAF) Sensor/Volume Air Flow (VAF) Sensor - Circuit --Malfunction Possible Cause:
-Wiring harness.
-Mass air flow (MAF) sensor.
-Volume air flow (VAF) sensor.
-Engine control module (ECM).
Error Code: P1491 Fault:
Exhaust Gas Recirculation (EGR) Valve Insufficient Lift Possible Cause: -Wiring harness.
-EGR Valve.
-ECM
Error Code:P1607
Fault:
-Engine Control Module (ECM)/Powertrain Control Module (PCM)
Error Code:P0966 Location:
-Pressure Control (PC) Solenoid B - Circuit Low Possible Cause:
-Wiring short to earth.
-Pressure control (PC) solenoid.
-Engine control module (ECM)/Powertrain control module -(PCM)/Transmission control module (TCM) .
TCS is a separate issue from PCM code. I would disconnect the plug from PCM and clean with contact cleaner. Most of the times humidity creates corrosion on the pins.
