By means of an ohmmeter check resistance between plugs close with adjusting ears. Resistance should equal 2 200 Ohm, otherwise the resistor/condenser is subject to replacement.

Disconnect electroconducting from the corresponding electromagnetic valve (location of the electromagnetic valve of a regulator of pressure of fuel of models of release till October, 1994 is shown on an accompanying illustration A, the valve of a purge of a coal adsorber - on an illustration B).

Disconnect from the corresponding valve electroconducting and vacuum hoses. At removal of the valve of a purge of a coal adsorber give a bolt of fastening of an arm of the valve to a cover of a head of cylinders and lift an arm so that access to a fixing nut of the valve opened. Give a fixing nut under an arm and remove the valve from the last.

Disunite the electric TPS socket.

At the closed butterfly valve resistance should make about 1 000 Ohm. At partially open zaslonka resistance should lie within 1 000 ÷ 9 000 Ohm. At completely open throttle resistance should make about 9 000 Ohm. Disconnect the tip of electroconducting of the sensor switch of idling from the TPS case. According to data of an illustration connect an ohmmeter to plugs A and B of the sensor switch of idling. At the closed butterfly valve between plugs conductivity should take place. At partially open zaslonka of conductivity should not be. If results of the made measurements do not meet standard requirements, check TPS adjustment and if to achieve satisfactory results it is not possible, replace the sensor.

Disconnect electroconducting of the sensor switch of idling from the TPS case, disunite the electric TPS socket. Give fixing screws and remove TPS from the throttle case.
