6.13.2.1. Check


Check of resistance between the corresponding contacts of the sensor of provision of a butterfly valve on four-cylinder engines

Check of resistance between the corresponding contacts of the socket of the sensor of provision of a butterfly valve on six-cylinder engines

PERFORMANCE ORDER
1. Disconnect the electric socket from the sensor of provision of a butterfly valve (TPS) and give vacuum to a throttle positioner.
2. Install the probe 0,7 mm thick between the screw of adjustment of turns of idling and an emphasis.
3. Using an ohmmeter, measure resistance between the corresponding couples of contacts of the electric socket (see rice. Check of resistance between the corresponding contacts of the sensor of provision of a butterfly valve on four-cylinder engines and rice. Check of resistance between the corresponding contacts of the socket of the sensor of provision of a butterfly valve on six-cylinder engines).
If the measured resistance differs from the required values, install the probe 0,7 mm thick between the screw of adjustment of turns of idling and an emphasis and connect an ohmmeter to contacts of IGL and E2. Weaken screws of fastening of the sensor of provision of a butterfly valve and slowly rotate the sensor clockwise until the ohmmeter shows infinity.
4. Tighten screws of fastening of the sensor of provision of a butterfly valve, install the probe and repeatedly measure resistance between the corresponding contacts.
