Your car’s MAF (mass airflow) sensor is an important part of any vehicle, as it determines both the volume and the density of air entering the engine. However, what should the MAF sensor read when it’s idle? In practice, there’s no one-size-fits-all reading, as your MAF sensor readings at idle can vary depending on the make and model of the car. Moreover, there are other factors to consider, like the size of your engine. For example, a 3.0-liter engine might …
Have you ever driven your car and then suddenly you’re not getting any power? And then your check engine light suddenly turns on? That means your car is in limp mode. A check engine light denotes that there’s something wrong with your car’s powertrain. It could be the engine, the gearbox, or the exhaust system. If this happened to you recently, don’t worry. We’ll discuss the limp mode in this post, from what it is, why it happens, and how …
Your car has a lot of sensors that feed information to the computer to keep it running smoothly. One such sensor you might not know of is the O2 or oxygen sensor. This is a sensor that sits in your exhaust system and monitors the level of oxygen inside your car’s exhaust gases. For such an important component, it’s not a surprise then that the O2 sensor cost isn’t inexpensive. As with any other car part, the O2 sensor can …
What Is A MAF Sensor? The Benefits Of Installing Common Problems And How To Fix Them Understanding The Different Types Diagnosing Issues How To Clean And Test What is a MAF Sensor and How Does it Work? A Mass Air Flow (MAF) sensor is an important component of a vehicle’s engine management system. It measures the amount of air entering the engine and sends this information to the Engine Control Unit (ECU). The ECU then uses this data to adjust …

It has been more than a century since the automobile was introduced. During this time, safety systems on vehicles have seen a vast improvement. Emergency braking assistance is one such feature. However, issues with this system can cause the “Service brake assist” light on the dashboard to turn on. What Is Brake Assist? Service Brake Assist Driving With Service Brake Assist Verdict FAQs Have you been looking forward to learning about this safety feature? Well then, you have come to …
To achieve optimum performance, an internal combustion engine needs the right air/fuel ratio. The engine control module controls the air/fuel mixture ratio going into the engine. It accomplishes this through the use of automotive sensors, one of which is the oxygen sensor installed on the car. When the circuit or sensor malfunctions, the onboard diagnostic system will display the P0137 error code. Vehicles have two oxygen sensors: one upstream (before the catalytic converter) and one downstream (the O2 sensors after …
P0300 Chevy is created when your engine experiences a misfire that is not limited to a single cylinder. This code is sometimes used in conjunction with others, such as P0301, which indicates a misfire on cylinder 1 (cylinder 1 being the first cylinder in the firing order). It’s usually the engine’s front-most cylinder. If these engine codes are also present, diagnose them first because they are most likely the source of this error code. Your check engine light will illuminate …
Modern car engines with emissions control systems rely on sensors to work well and control how much pollution they put out. If these sensors malfunction and provide incorrect data, you may notice issues such as reduced MPGs, driving difficulties, emissions failure, and other issues. The P0130 error code helps us identify such issues. P0130 is a diagnostic trouble code (DTC) that relates to “O2 Sensor Circuit Malfunction (Bank 1, Sensor 1),” suggesting a problem with the air-to-fuel ratio sensor (aka …
Modern vehicles often have tire pressure sensors, but few people are actually familiar with how they operate. Many don’t even know where are tire sensors located. There are a lot of myths about where are tire sensors located and how they interact with the ECU of your car. Additionally, many people are clueless when their tire pressure sensor detects low readings or when the car sensor isn’t working properly. To learn more about how tire pressure sensors operate, continue reading. …
