The modern automobile is far more complex in nature than most would imagine. In fact, today’s cars, trucks, and SUVs operate through a complex network of computers, sensors, and wiring. The structure of this network makes communication between various vehicle systems possible. As such, operating efficiency is significantly enhanced. <\/p>\n
A significant portion of this network is specifically designed to minimize noxious emissions output, through the more stringent control of combustion. Aiding in these efforts is a series of oxygen sensors, which provide the PCM\/ECM with direct feedback regarding combustion efficiency. While this design has proven highly successful, the occasional issue of sorts does arise on occasion.<\/p>\n
One such issue is that which pertains to diagnostic trouble Code P0157. This code is indicative of voltage-related problems within the bank 2, sensor 2 power circuit. As such, sensor operation is compromised, leaving a vehicle\u2019s ECM\/PCM without a wealth of valuable feedback <\/p>\n
Read on to learn more about DTC P0157, as well as how to remedy such issues, should they arise in the future.<\/p>\n
