Check

 PERFORMANCE ORDER

  1. Uncover the distributor (The head Nastroyki and routine maintenance).
  2. Insert into a back part of the socket of a plait of wires of the distributor the straightened paper clips or wire pins for ensuring contact with plugs. Try not to damage a plait at installation of pins.
  3. Connect a positive wire of the voltmeter to an output wire of the sensor (see an illustration). Be verified with schemes in the Head Sistema of onboard electric equipment.
  4. Having connected the voltmeter:
    • On the 4.0 l engines turn the engine a starter so that the runner of the distributor turned in situation for 10 hours. The ring of the sensor will enter the magnetic induction sensor.
    • On engines of 5.2 l turn the engine a starter so that the runner turned on the engine back. The mobile ring of the sensor will enter the magnetic induction sensor.
  5. At turn of the ignition key in position of ON (without start of the engine) the voltmeter has to show value about 5B.
  6. If tension is absent, check tension on a food wire (white-black). It has to equal about 8 V at the key turned in situation by ON.
  7. If tension is present, connect the voltmeter probe to an alarm wire (black-gray) and turn the engine, watching instrument readings. Indications have to fluctuate between zero and 5.0 B that speaks about the correct pulsation of a signal of ignition.
  1. Connect the positive probe of the voltmeter to black gray wire of the socket of the sensor of position of the camshaft and make sure that its indications pulse between values 0 and 5.0 B.
  1. If the sensor of position of the camshaft does not pass any of the listed checks, replace it.

Replacement

V8 engines are equipped with the sensor of position of the camshaft which can be taken from the distributor without removal of the last from the engine (independent type) whereas for removal of the sensor on 6-cylinder engines it is necessary to disassemble before the distributor (the sensor of dependent type).

Sensor of dependent type (V8 engines)

 PERFORMANCE ORDER

  1. Disconnect a negative wire from the battery.

If the radio tape recorder in your car is equipped with a security code before disconnecting a negative wire from the battery make sure that you know this code.

  1. Uncover with the distributor (The head Nastroyki and routine maintenance).
  2. Disunite electric sockets of the sensor of position of the camshaft.
  3. Take the sensor from the distributor.

Extraction of the sensor of position of the camshaft of independent type from the distributor.

  1. You make installation upside-down.

Sensor of dependent type (6-cylinder engines)

 PERFORMANCE ORDER

  1. Disconnect a negative wire from the battery.

If the radio tape recorder in your car is equipped with a security code before disconnecting a negative wire from the battery make sure that you know this code.

  1. Remove the distributor (The section Removal and installation of the distributor).
  2. Mark the provision of a gear wheel and shaft in relation to a cylindrical pin - it is useful.
  3. By means of a small drift take a cylindrical pin (finger) from a distributor shaft.

Components of the distributor of dependent type.

  1. Remove a gear wheel and a persistent washer from the distributor.
  2. Take a distributor shaft from the case.
  3. Give the screw of fastening of the sensor of position of the camshaft and remove the lever.
  4. Take the plug of a plait through passage of wires from a cut in the case of the distributor and take the sensor.
  5. You make installation upside-down.
