Today\u2019s vehicles rely upon an intricate web of sensors, wires, and modules to promote efficient operation. The data shared through this network is processed by a vehicle’s ECM\/PCM<\/a> and is used to calculate figures such as injection timing, as well as injector pulse width.<\/p>\n

As a side benefit of this data transmission, today\u2019s highly efficient vehicles run far cleaner than ever before. This is largely due to the ability of most engines to figure the correct air\/fuel ratio under any particular load, with a high degree of precision.<\/p>\n

A series of oxygen sensors are used to detect overly rich\/lean exhaust conditions, thereby making it possible to remedy such conditions on the fly. However, oxygen sensors are prone to failure with time, presenting numerous issues along the way.<\/p>\n

Such issues are often brought to light with the sudden illumination of a check engine light on a vehicle\u2019s instrument cluster, which signifies that an active diagnostic fault code has been stored. Of these O2 sensor-related fault codes, perhaps none are as prevalent as DTC P0137.<\/p>\n

Read on to learn more about DTC P0137, as well as how to remedy such issues, should they occur.<\/p>\n
