Question

El código p 0037 puede hacer que el carro no encienda cuando está frio y si arranque a los tres o cuatro intentos.

Answer 1

P0037 H02S heater control circuit low voltage sensor 2

This is the rear 02 sensor or the catalytic sensor, Yes it will. The only way this sensor can cause a hard to start is if the rear 02 sensor is grounding out and affecting the operation of the fuel injector power supply, in which you will have to replace the Main relay and the rear 02 sensor.Low voltage at this sensor will result in low injector voltage.
