Here is what is said about the codes:
P0300 - Random/Multiple Cylinder Misfire Detected: This code indicates that the engine control module (ECM) has detected misfires occurring in multiple cylinders or in an unpredictable pattern. The underlying causes can vary and may include issues such as spark plug problems, ignition system faults, fuel delivery issues, or engine mechanical problems. Proper diagnosis is necessary to identify the specific cylinder(s) experiencing misfires and determine the appropriate repairs.
P0131 - O2 Sensor Circuit Low Voltage Bank 1 Sensor 1: This code indicates that the oxygen sensor (O2 sensor) located in the exhaust system before the catalytic converter (bank 1 sensor 1) is reporting a low voltage condition. The cause could be a faulty O2 sensor, wiring issues, or an exhaust system leak. The O2 sensor helps measure the air-fuel mixture, and a malfunctioning sensor can lead to poor fuel economy, emissions problems, or drivability issues.
P0151 - O2 Sensor Circuit Low Voltage Bank 2 Sensor 1: Similar to P0131, this code indicates a low voltage condition in the O2 sensor located before the catalytic converter on bank 2 sensor 1. The diagnostic and repair steps are similar to P0131, but this code applies to a different O2 sensor on the opposite bank of the engine.
P1870 - Transmission Component Slipping: This code is specific to automatic transmissions and indicates that the ECM has detected abnormal slippage or slipping behavior in one or more transmission components. It could be caused by a faulty torque converter, worn clutch plates, hydraulic issues, or a malfunctioning solenoid. Proper diagnosis by a qualified transmission specialist is necessary to identify the specific cause and recommend the appropriate repairs.
P0102 - Mass or Volume Air Flow Circuit Low Input: This code indicates that the ECM has detected a lower than expected voltage or signal from the mass airflow sensor (MAF). A faulty MAF sensor, a vacuum leak, or issues with the intake system can cause this code. A low input signal from the MAF sensor can affect the air-fuel mixture and lead to drivability issues such as poor acceleration or rough idling.
The only codes that can affect the engine running is the MAF I would get a new one and install it. Here is how in the diagrams below.
