1. In the included ignition desconectam an electrical system of the sensor IAT located in the oil pipeline of entry (companion sees an illustration). Through an ohmmeter they measure the resistance between two captures in the sensor. The resistance of the sensor depends on the temperature (companion sees the table). |

2. In the included ignition (they do not begin the motor) they measure the basic tension in captures of capture of electrical system of sensor yellow-red (wire) (to see an illustration in top). The result of the measurement will do approximately 5 V, otherwise walk in a wire the ECM/PCM, when intervals existence is checking it and fixing of contact connections.
3. If an electrical system as debit to be, substitutes the sensor IAT.
4. If the substitution of the sensor does not lead to the elimination of a problem, the car must be expelled in the workshop of repairs of the car of the realization of the diagnostic one of ECM/PCM. |
