P0161 Code (Symptoms, Causes, and How to Fix)

P0161 code

Today’s vehicles rely upon an intricate web of electronic controls to increase operating efficiency, and to reduce emissions output. Such technology initially arose in the 1970s, under regulatory pressure from the US government, in a bid to reduce the nation’s carbon footprint.  Modern vehicles are now able to monitor their own performance, thereby making on-the-fly … Read more

P0131 Code (Symptoms, Causes, and How to Fix)

P0131 code

Today’s vehicles are designed to operate in the most efficient manner possible, making the most out of each combustion cycle. This is accomplished through the monitoring of engine-related data, by a dedicated engine computer, known as an ECM.  This computer relies upon feedback from various sensors when determining appropriate fuel trims and throttle plate positioning. … Read more

P2135 Code (Symptoms, Causes, and How to Fix)

P2135 code

Today’s vehicles are nothing short of highly complex when compared to those of previous generations. Modern vehicles rely upon a series of sensors and circuits, as well as several control modules, to facilitate proper operation. In most cases, these electronics are now tasked with completing many of the same jobs that were once controlled in … Read more

During the late 1970s, the automotive world underwent a series of rather monumental changes. A new found consciousness for environmental-related concerns led to a flurry of legislation aimed at curbing the output of exhaust-born pollutants.  This agenda ultimately led to the mandate of new emissions equipment, aimed at cleaning up engine exhaust. Of these components, … Read more

P0304 Code (Symptoms, Causes, and How to Fix)

P0304 code

Few sounds are sweet as that of a well-tuned, smooth idling engine. One cannot help but to marvel at the value of such mechanical perfection. However, even the heartiest of engines are prone to the occasional mechanical hardship. Of these issues, few are as prevalent as the dreaded misfire. Misfires are not only evident to … Read more

P0137 Code (Symptoms, Causes, and How to Fix)

P0137 code

Today’s 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 and is used to calculate figures such as injection timing, as well as injector pulse width. As a side benefit of this data transmission, today’s highly efficient … Read more
