 Don't ruin your car engine.  Trial and error sucks Know sensor  Knock sensor  Knock sensor  Circuit Description  A flat type knock sensor (non–resonant type) has the structure that can detect vibration in a wider band of the frequency from about 6 kHz to 15 kHz and has the following features. Knock sensors are fitted on the cylinder block to detect engine knocking. The knock sensor contains a piezoelectric element which generates voltage when it becomes deformed. The generation of the voltage occurs when the cylinder block vibrates due to the knocking. If the engine knocking occurs, in order to suppress it, the ignition timing is retarded. MONITOR DESCRIPTION The knock sensor, located on the cylinder block, detects spark knocks. When the spark knocks occur, the sensor picks–up vibrates in a specific frequency range.  When the ECM detects the voltage in this frequency range, it retards the ignition timing to suppress the spark knock. The ECM also sense...

Engine coolant temperature sensor helps: In sensing engine coolant temperature and overall engine temperature it helps the ECU/PCM to properly control the fuel injector pulse rate, especially at colder temperature to improve engine performance and avoid stalling  improving drivability, at colder engine temperature it helps in maintaining optimum fuel economy SYMPTOMS OF P0116 IN TOYOTA  Check engine light on hard acceleration, especially at colder engine temperature excessive fuel consumption intermittent engine misfiring - at times everything seems alright, next minute you'll feel difficulty in revving the engine, with shooting sound. You'll have to press hard on the throttle pedal before the engine can move. at times you'll resolve the exhaust is restricted, at other times, the symptom will be that of a bad fuel pump. at times you'll count a misfire from number 1 cylinder. BUT WHEN YOU HAVE ALL THIS SYMPTOMS AND NO DTCs, it's likely that you have a bad fuel pum...

As a car owner, you need at least a basic auto diagnostic tool to help you have the first hand knowledge of your vehicle, even before you call a mechanic.  When an original diagnostic tool detected a fault on your vehicle, it will suggest some ways and steps you will take to fix that problem.  If you're connected to Internet, it'll link you to video tutorials of how that particular problem is being solved. What does this means to you? You reduced your repair cost,  when you have the first-hand knowledge of your vehicle, your calling a mechanic is to just tell him what he'll help you do, already, there's no need for further diagnosis,  he/she will hardly lie to you as a means of extorting  some extra money from you  You'll hasten the work as you're going straight to where the fault is, there'll be no need for trial and error. When you earlier diagnose an early check engine light,  it'll  be easier for you to solve it, preventing the faults from esc...
