Check and replace the fuel temperature sensor Vehicle speed (VSS)

Perform the following procedure may result in a memorized OBD fault, which will be displayed control lamp "Check up the engine". Upon completion of inspection and corresponding regenerative repair do not forget to clean the system memory (see. Section System of onboard diagnostics (OBD) - a principle of functioning and codes of malfunctions).

1. Remove the rear seat and the access cover to the assembly of the fuel pump / gauge of fuel (see the chap. The power supply system and release).
2. Make sure of serviceability of giving to the sensor temperature of the fuel supply. Disconnect the wiring from the sensor assembly flow / temperature of the fuel. Connect the positive lead of the voltmeter to the terminal pink-blue wire connector, negative - to the plug of a black wire. Ignition instrument reading should be 5.0 V, otherwise check up an electroconducting condition on a chain site between the sensor and the PCM / weight. If the wiring is okay, drive to a repair shop for diagnostics and performance management module corresponding regenerative repair.

3. Using an ohmmeter, measure the resistance between the two terminals of the fuel temperature sensor. At room temperature (20 ?� C), the sensor resistance should be 2300 ÷ 2700 Ohm. A more accurate check of serviceability of functioning of the sensor can be made by removing it from the car and lowered into a heated container on the fire with water. Compare results of measurements to map the change in resistance. Faulty sensor must be replaced.

1. Remove the sensor assembly from the tank of fuel (see the chap. The power supply system and release).
2. Remove the assembly from the fuel temperature sensor.
3. Install in the reverse order.
