check your O2 sensor and wires other thinks that can cause that problem is when the engine is running in close loop. u should check if the other codes have to do anything with the coolant system. u should fix the other codes first and see if the p0157 go away.

Testimonial: "Thank you!"
- Front Heated Oxygen Sensor Bank 1 harness is open or shorted
- Front Heated Oxygen Sensor Bank 1 circuit poor electrical connection
- Faulty Front Heated Oxygen Sensor Bank 1
- Inappropriate fuel pressure
- Faulty fuel injectors
- Intake air leaks may be faulty
- Exhaust gas leaks
Replacing the O2 Sensor 1 usually takes care of the problem
The front heated oxygen sensor (or O2 sensor 1) is placed into the exhaust manifold. It detects the amount of oxygen in the exhaust gas compared to the outside air. The heated oxygen sensor 1 has a closed-end tube made of ceramic zirconia. The zirconia generates voltage from approximately 1V in richer conditions to 0V in leaner conditions. The heated oxygen sensor 1 signal is sent to the Engine Control Module (ECM). The ECM adjusts the injection pulse duration to achieve the ideal air-fuel ratio. The ideal air-fuel ratio occurs near the radical change from 1V to 0V.

Tips for a great answer:
Oxygen O2 Sensor Circuit Low Voltage (Bank 1, Sensor 1)
What does that mean? Essentially the same as P0136 and P0137, a P0131 code refers to the first oxygen sensor on Bank 1.
P0131 means the O2 oxygen sensor's voltage remained low for longer than 2 minutes. This, is interpreted by the ECM as a low voltage condition and sets the MIL. Bank 1 Sensor 1 is located in front of the catalytic converter.
Symptoms There may be no visible symptoms to the driver, other than the MIL (Check Engine / Service Engine Soon) illumination.
Causes A code P0131 may mean that one or more of the following has happened:
