Automotive Sensors: Descriptions & Information
Welcome to the Automotive Sensors Information Page! This is where you can find out nearly everything you ever needed to know about the sensors in your car. We cover the basic automotive sensors such as oxygen sensors, throttle position sensors and mass air flow sensors, but we also cover the ones that are a little more difficult to find info about.
These include ones such as knock sensors, camshaft and crankshaft sensors and map sensors. We are adding and updating these pages daily so be sure to check back frequently and refresh your browser. We also suggest taking a look at the incredibly useful
4-in-1 Diagnostic Guide which includes the OBDII Guide, Sensor Guide, Emissions Guide, and Diagnostic Trouble Code Guide. These resources are no longer just for professional technicians! Our goal here is to make sure you have all the information you need to understand how a sensor works, what ranges they usually operate in and where to find them! We will be providing links to assist with specific component location or specification questions that should help you to determine if you have a problem with your sensor! These pages can be used in conjunction with the remainder of our site to help you correct issues you may be having with your check engine light! Let us know if you have any suggestions for improvements of this area of the site. We are also researching a number of sites to provide you access to quality replacement parts at the lowest prices anywhere! This too should help to make fixing that check engine light a little less painful! Take some time to look around and we hope you find something helpful!
- Get the complete story on your oxygen sensor including how it works and what to look for when diagnosing related concerns. Old and new style sensors alike, you'll get the info your looking for.
Mass Air Flow Sensor
- The mass air flow (MAF) sensor can be a problematic sensor as it will not always trip the check engine light when there is a problem with it. We'll let you know what these sensors do, how they do it and how to approach testing them for faults!
Throttle Position Sensor
- So what do you need to know about throttle position sensors? Whatever it is, you'll likely get the answer here. Learn about common symptoms of a faulty TP sensor and much more!
Vehicle Speed Sensor
- Vehicle speed sensors are involved in more tasks than nearly any other sensor in a modern automobile, so it's important to know exactly what these sensors do and why! Get educated and help yourself out when diagnosing VSS related check engine light concerns!
