What is Engine Sensors?
A modern car’s Engine Management System consists of various electronic and electrical components. Moreover, these comprise engine sensors, relays, and actuators. They provide the car’s Engine Control Unit with vital data parameters essential to govern various engine functions effectively.
Engine sensors are elector-mechanical devices that monitor various engine parameters. An engine uses different types of sensors such as Thermocouples, Resistance Temperature Detectors (RTDs), and Hall Effect sensors.
A Modern-day Car Has The Following Sensors:
|SL.||Name of the Sensor||Purpose|
|01||Air- fuel Ratio meter||It monitors the correct air-fuel ratio for the engine|
|02||Engine Speed Sensor||It monitors engine speed|
|03||Throttle Position Sensor||Further, it monitors the position of the throttle in an engine|
|04||Crank position sensor||Monitors piston’s TDC position in the engine|
|05||Cam Position Sensor||Further, it monitors the position of valves in the engine|
|06||Knock Sensor||Detects engine knocking because of timing advance|
|07||Engine coolant temperature sensor||Moreover, it measures the engine temperature|
|08||Manifold Absolute Pressure or MAP Sensor||Used to regulate fuel metering|
|09||Mass Air Flow or MAF Sensor||Further, it notifies the mass of air entering the engine to ECU|
|10||Oxygen/02/lambda sensor||It monitors the amount of oxygen in the exhaust|
|11||Fuel Pressure Sensor||Additionally, it measures pressure in the fuel system|
|12||Vehicle Speed Sensor (VSS)||Measures the speed of a vehicle|
Furthermore, the Electronic control Unit sends signals to various relays and actuators after calculating the fuel quantity. They include the ignition Circuit Spark Plugs, Fuel Injectors Engine Idling Air Control valve, and Exhaust Gas Re-circulation (EGR) valve. Thus, it extracts the best possible engine performance while keeping emissions as low as possible.
Since all the engine sensors connect to the ECU, it can also monitor them for malfunction. Besides, the ECU collects signals from faulty engine sensors. Then again, the ECU stores them in its memory. So, you can diagnose these faults through two methods. Firstly, by reading the ECU memory with the help of ‘fault codes.’ Or diagnostic with any available car scanner or blou tooth device like ELM 327 or other

Very good blog post. I absolutely love this website. Keep writing!
I visited a lot of website but I believe this one has something special in it in it
Good post. I learn something new and challenging on sites I stumbleupon every day. It will always be exciting to read through content from other writers and use a little something from other sites.
Youre so cool! I dont suppose Ive read something like this before. So good to find anyone with some unique ideas on this subject. realy thank you for beginning this up. this web site is something that is needed on the web, someone with somewhat originality. helpful job for bringing one thing new to the internet!
Perfect piece of work you have done, this site is really cool with wonderful info .
I’ve been surfing online more than 3 hours today, yet I never found any interesting article like yours. It’s pretty worth enough for me. Personally, if all web owners and bloggers made good content as you did, the web will be much more useful than ever before.
