In cases where there is a clear decrease in the dynamics of the car, and even more so when the "Check …" indicator on the instrument panel lights up, then all engine systems should be diagnosed. Perhaps the cause of the malfunction was a malfunction of the crankshaft position sensor.

ohmmeter
Instructions
Step 1
The crankshaft sensor, installed in different places of the engine, depending on the make and model of the car, is designed to transmit an electrical signal to the ECU, informing the system at what angle the crankshaft is currently located.
Step 2
Based on the received data, the ECU (electronic control unit) gives the command to supply fuel and spark discharge in a specific cylinder. Consequently, a failure in the transmission of data by various electrical devices, not excluding the crankshaft sensor, entails a deterioration in the performance of the engine, which is reflected in a decrease in the dynamics of the car while driving.
Step 3
The appearance of the above "symptoms" will further lead to the failure of the crankshaft position sensor, and the car engine will stop starting. Assistance in determining the parameters of the specified sensor can be provided during the diagnostics at the car service station.
Step 4
But what should those motorists who still have to get to the nearest car service station, and it is far from the fact that the car will get there on its own? There is only one way out of this situation: check the crankshaft sensor yourself.
Step 5
To perform this check, it is necessary to dismantle the sensor from the engine and measure the resistance of its winding with an ohmmeter, which should be equal to 550-750 Ohm for a working sensor.
Step 6
Any deviations from the specified values indicate a malfunction of the specified electrical equipment, which must be replaced.
