The next sensor that we will talk about, and which greatly affects the operation of the engine, is the camshaft position sensor. Externally, it looks like a crankshaft position sensor. And even the principle of operation is similar, but that's where the similarities end. This sensor is solid-state.
In my practice, this sensor has failed. This manifested itself in the poor acceleration dynamics of the car (as they say, the engine was "dumb"), the maximum speed was 70, and then downhill. But fuel consumption has more than doubled. I had to drive about two hundred kilometers, and 80 liters of gasoline burned out and flew into the muffler. The reason for the sensor failure, it seems to me, is a violation of the temperature regime. It is installed in the hottest place of the engine, in the upper rear part of the block head, above the exhaust manifold. Well, even schoolchildren know that semiconductors do not like excessive heat.
So, back to our sensors. The fault code is 54. But do not rush to immediately change this sensor, as well as any other one. If there is a malfunction in the wiring, you can easily disable a new sensor.
Therefore, using a multimeter, we will check the wires connecting the sensor to the electronic unit. To do this, turn off the ignition, remove the negative terminal from the battery, disconnect the sensor from the wiring harness, disconnect the connector from the electronic unit.
Next, turn on the multimeter in the ringing mode, connect the probes to each other. We hear a beep, the device is ready, and we start checking.
We check the integrity of the wires. We connect one probe to the eighth contact of the electronic unit connector. Another probe with the second contact of the sensor outlet. There must be a signal. If not, it means a cliff. We find and eliminate them.
Then, we connect one probe to the thirty-seventh contact of the electronic unit, and the other probe to the first contact of the sensor outlet. There should be a signal too. If not, it's a cliff. We find and eliminate them.
Then we connect one probe to the third contact of the sensor outlet, and the other to the "mass". There must be a signal.
Now let's check this section of the wiring for a short circuit. To do this, connect one probe to the first contact of the sensor outlet, and the other to the second contact of the same outlet. There should be no signal. If there is a signal, then the wires are closed to each other, and the wiring needs to be repaired. Or better yet, replace it.
We also check the first contact of the sensor outlet and the third contact for a short circuit. Then the second and the third. In both cases, there should be no signal.
When all the faults are found and fixed, we connect the sensor and the electronic unit to the wiring, put the terminal on the battery, install the jumper, turn on the ignition (without starting the engine) and make sure that the code 54 is missing. Everything is fine?
Turn off the ignition and remove the jumper. Turn on the ignition. The indicator light in the instrument panel should go out quickly. Starting the engine.
