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 … Read more
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 … Read more
There are few things more terrifying than starting up your car only to see a check engine light staring at you. You rush your vehicle to a mechanic or a part store to figure out what the code is, only … Read more
A modern vehicle’s onboard diagnostic system is easily capable of uncovering operational faults, thereby storing each for later review. These faults are known simply as DTCs (Diagnostic Fault Codes). Codes of this nature point to the underlying cause of whatever … Read more
Few things will stress you out more than a check engine light. But once you’ve pulled your heart out of your throat and checked what your vehicle’s check engine light means, you’re presented with a whole new list of questions. … Read more

Combustion engines are not machines that you can tune perfectly and then expect to run that way forever. They need constant readjusting to run efficiently. Technology in modern cars works to make these small adjustments as you drive. Sometimes, even … Read more
Some oxygen sensors contain a heating circuit to reduce the time it takes them to reach operational temperature after the vehicle is started. The P0135 code is activated when the heating circuit in the air-to-fuel ratio sensor, also known as … Read more
In this article we are going to go over a very important sensor in a car’s engine called the “oxygen sensor”, commonly referred to as an O2 sensor. Afterwards, you should know the basic function, working principle, bad symptoms, and … Read more
