In addition to 5A-FE
1. Remove the relay switch top-tidal pump.
2. Check the circuit relay.
a) Using an ohmmeter, verify that you have a closed circuit between you, the waters of the relay, "ETA" and "E1" and "+ B" and "RS".
b) Using an ohmmeter, verify that you break the chain between the conclusions ¬ DAMI "+ B" and "PP".
If these conditions are not satisfied ¬, replace the relay. 3. Check the operation of the relay.
a) Move the voltage of the battery accumulates ¬ lyatornoy to conclusions, "this" and "E1" and use an ohmmeter to ensure that there is conductivity between you ¬ waters "+ B" and "PP".
b) Move the voltage of the Accu-mulyatornoy battery to terminals "+ B" and "PC" and use an ohmmeter to convincingly re-quest in the absence of conduction between the terminals' + B "and" PP ". If the work does not comply with the relay because of false, replace the relay.
5A-FE (AE110), 4A-FE (AE111), 7A-FE (AE115)
1. Remove the fascia (dash) with a one hundred-hand driver, and then remove the relay switch the fuel pump.
2. Check the circuit relay.
a) Using ohmmeter, ensure that there is conductivity between you, the waters of "1" and "2".
b) Using an ohmmeter, verify that no conduction between terminals "3" and "5".
If these conditions are not satisfied, replace the relay.
3. Check the operation of the relay. Move the voltage of the battery accumulates ¬ lyatornoy to conclusions "1" and "2" and use an ohmmeter to ensure that there is conductivity between the water-you "3" and "5".
If the work does not meet the laid down relay, replace the relay.
4. Set the relay switch.

Coolant temperature sensor and the intake air temperature (engine without the air flow meter)
Coolant temperature sensor has a built-in thermal control ¬ zistor whose resistance from ¬ varies depending on the tempera ¬ tours of the liquid (the lower the temperature - the higher the resistance, and vice versa ¬ mouth, the higher the temperature - the same resistance nor ¬). The sensor is connected to the electronic com ¬ block controls the output of the "TNM" ¬ torogo to him through a resistor, since ¬ quently connected to a sensor receives the supply voltage (5V). If you change the sensor resistance changes as the voltage on you ¬ water THM. "Based on these signals, the electronic control unit increased ¬ Chiva fuel supply to improve cold engine. When on-naruzhenii failure (code 22), an electronic control unit ustanav ¬ Lebanon operation in which the coolant temperature is maintained at 80 ° C. Air temperature sensor on vpus-ke is built into the air filter cover on the Executive Board, compared constructive and the principle of it analogous gichen temperature sensor gives the cooling fluid.
