Camshaft Sensor Chevrolet Aveo
This video presents the diagnosis of fault code P0340, which refers to the failure of the camshaft position sensor, in this Chevrolet Aveo vehicle, and may also have any of the following elbows: P0341, P0342 and P0343, concerning the camshaft position sensor, cmp sensor (cmp sensor)
In the context of the failure, I present the preliminary conditions in which the camshaft sensor failure occurs and these are: the change of the timing belt, tuning consisting of an oil change, air filter, gasoline filter and fuel filter. oil, as well as the change of spark plugs and maintenance to the injectors, throttle body and IAC valve, likewise with the help of the smoke machine it was detected that there was a vacuum leak in the intake manifold leagues, proceeding to change them .
I also make the comparisons of the Aveo camshaft sensor, one bought online through MercadoLibre and a second original GM sensor.
I also present several examples of pirate spare parts for the car, and I conclude that the timing kit, due to its jumps in the belt and noises in the tension pulley and idler pulley, is of low quality.
Following the instructions provided by the client, I proceed to test the fuel pressure, not finding a problem with the fuel pump, but sometimes we ask ourselves "why does my car take time to start" or "the Aveo takes time to start"
Subsequently, the engine computer was scanned, finding the P0340 code, referring to the cmp Aveo, or camshaft sensor, so we can have an idea of what the camshaft sensor is for, and later it will be diagnosed and shown as test camshaft sensor.
As an example of diagnosis, the diagnosis P0011 and P0014 Sonic, Cruze and Trax is presented, as well as the alternator ripple test, or rectification of the alternator diodes and test of the charging system, as a comparison to the diagnosis of code P0340, which is the reason of the video.
The procedure to change the Aveo camshaft sensor is presented, with information on the torques and parts to remove, giving assembly and disassembly tips.
The diagnostic procedure for the solution of the fault is presented, presenting the diagrams of the harness and test voltages, as well as the camshaft sensor tests with an oscilloscope.
As verification tests of the car's electronics, the alternator ripple test was carried out, or rectification of the alternator diodes and a test of the charging system, with no problems being found.
