Replacing the phase sensor (camshaft position) on the VAZ 2114

A few months ago, the following problem arose on my 2114: when the ignition was turned on and the engine was started, after a few seconds, the “check” injector lamp on the instrument panel began to light up. At first I thought that this was a temporary problem and this was due to the quality of gasoline, but after re-refueling, the problem did not disappear and the check still lit up in almost every case after starting the engine.

The surest way to determine which sensor from the ECM system has failed is to install an on-board computer, such as the State, which, in the event of an engine error, immediately reports on the rey and decrypts it.

I did the same, I thought about buying for a long time, but after this problem I decided not to postpone and immediately install it. As a result, after connecting the BC State, the display showed me error 0343 - a high signal level of the phase sensor. When I turned it off, I did not see any changes in the operation of the engine, and the “injector” light continued to burn. In the end, it was decided that it needed to be changed.

First you need to open the hood of the car and on the right side, where it is marked with an arrow in the photo, it is located:
