You will need
- tester (multimeter)
Look on the cylinder head of the engine installation angle position sensor camshaft (DPRV). Check the o-ring for damage. Make sure that the housing of the sensor and the toothed rotor are also lacking any damage and metal particles.
Making sure the ignition on the car off, disconnect the sensor from coming to him the power wires and the engine management system. Usually these wires are attached to standard connectors, so disconnection of the wires just press the lock pad. Note the harness connector. It should have three pins: positive supply pin (positive), the mass contact (minus) and signal contact.
Turn on the car ignition. With a voltmeter (tester), measure the voltage at the positive supply wire of the camshaft position sensor. While the negative probe of the device connect to ground of the engine. Thus measured voltage should correspond to voltage at the battery terminals. If the measured voltage corresponds to the supply means, the power supply circuit of the sensor faulty. In exactly the same way, measure the voltage of the terminal to the sensor ground. It must be zero.
Connect the positive and negative power wires DPRV. When connected secondary (signal) sensor wires run through that connect voltmeter (tester). In other words, one of the probes of the voltmeter should be touching the signal output of the transducer, the other signal input of the engine control system. In most cases it will have to cut the signal wire and to the ends of exposed wires to connect the tester.
Rotate the engine using stratera. Good sensor should show a voltage swing from zero to 5 volts. If the sensor is faulty, replace it with a new one. To do this, unplug all of his wires, Unscrew the bolt of its fastening and remove DPRV from the distribution slot. The installation of a new swipe sensor in the reverse order. Tightening torque mounting bolts should be 10 Nm. Don't forget to install the rubber seal at the connection of the sensor and the head unit.
Advice 2 : How to check the phase sensor
Sensor phase the car is on the oil pump cover. It gives the controller the necessary information about the angular position of the crankshaft and the time of passage of the pistons of the first and second cylinder. With the passage of depressions on the teeth sinking of the disc on the pulley of the generator past the sensor it generates a reference sync pulse. To remove and test the sensor you must perform the following steps.
You will need
- key to 10;
- - flat screwdriver;
- - multimeter;
- - megger.
Put the car on a viewing hole or overpass, so as to reach the phase sensor convenient from below. Turn off the car ignition. Disconnect the negative cable from the battery. Remove engine protection from below with a screwdriver unscrewing the four bolts on its cover. Access to the oil pump of the engine is opened. The phase sensor near the oil filter pump.
Disconnect the connector of phase sensor. Remove key for 10 bolt. Remove the sensor from the bracket on the oil pump cover. Now it must be checked.
Perform a visual inspection of the sensor to identify damage to the hull, core, contact pads and contacts. Clean the contacts of the alcohol-gasoline mixture. Clean the sensor core from metal particles and dirt.
Measure the sensor resistance with a multimeter. Set the appliance switch to the 2000 Ohm position. Connect the contact device to the sensor. The resistance of a good sensor should be in the range of 550-750 Ohm (the data for the car VAZ-2109). Verification must be carried out at a temperature of 22±2 ° C, it is necessary to consider the error of the measuring device.
Check the inductance coil of the sensor between the contacts of the first and second pads with a meter R (L, C, E7-8) at 1 kHz. The inductance should be in the range 200-420 MHz.
Measure the insulation resistance of the sensor between the core and the contacts of the first and second pads with the help of megger Ф4108/1. The value of resistance shall not be less than 20 MW at a voltage of 500 V.
Replace the phase sensor the new. Perform its installation on the oil pump cover in the reverse order. Attach the protection cover of the engine.
Health check of the sensor phase can be done at engine idle speed according to the frequency of pulses at the injector. Defective phase sensor gives a frequency of 6-7 Hz, faulty - 12-14 Hz.
