Discuss malfunctions on VKontakte: https://vk.com/club_autotema Sometimes your car won't run, you go for diagnostics, they check something, say everything's fine, and charge you 500 rubles. But the car still won't run... Let's look at what a proper car diagnostic is. Why isn't the check engine light on? For example, if the mass air flow sensor (MAF) is giving an incorrect reading, the check engine light won't come on, but the car won't start or stalls at an intersection. How to check the MAF with a multimeter. Measure the ADC voltage. The oxygen sensor also doesn't always show an error, but the car starts guzzling gas and fuel consumption increases. Check the oxygen sensor using voltage. This is the proper diagnosis. How to identify a faulty ignition module if there are no errors and the check engine light isn't on? Check for spark, measure the resistance of the high-voltage wires, and remove and check the spark plugs. Check the insulator to see if there's a spark. Check the injectors using parameters and a test bench. Check the injection timing. Is the fuel system or fuel trim working properly? Coolant temperature sensor malfunctions. How does it affect fuel consumption and why won't the car start? Idle air control valve. Fluctuating RPMs are caused by the idle air control valve or the electronic throttle on a Priora, for example.
