Check of a condition and replacement of the sensor of temperature of fuel of speed of movement of the car (VSS)

In a complete set of some models since 1995 вып. the sensor of temperature of fuel enters. The sensor serves for measurement of temperature of the fuel which was in a fuel tank and is a termistor which resistance changes in inverse proportion to temperature. The sensor is fixed on the assembly of the sensor of fuel consumption placed in a tank. Information arriving from the sensor is used by RSM in the diagnostic purposes. Failures of the sensor lead to record in memory of OBD of the corresponding code of malfunction (see. The section System of onboard diagnostics (OBD) - a principle of functioning and codes of malfunctions).

CHECK

 PERFORMANCE ORDER

 Performance described below procedure can lead to entering in memory of OBD of malfunction which will be highlighted by a control lamp “Check the engine”. On termination of check and the corresponding regenerative repair do not forget to clear memory of system (see. The section System of onboard diagnostics (OBD) - a principle of functioning and codes of malfunctions).

1. Remove a back seat and a cover of access to assembly of the fuel pump/sensor of fuel consumption (see. Head of the Power supply system and release).
2. Make sure of serviceability of giving to the sensor of temperature of fuel of a food. Disconnect electroconducting from assembly of the sensor of a consumption/temperature of fuel. Connect positive щуп the voltmeter to the plug of a pink-dark blue wire the socket, negative - to the plug of a black wire. At the included ignition instrument reading should make 5.0 In, otherwise check an electroconducting condition on chain sites between the sensor and RSM/weight. If conducting as it should be, drive away the car on car repair shop for carrying out diagnostics of the module of management and performance of the corresponding regenerative repair.

3. By means of an ohmmeter measure resistance between two plugs of the sensor of temperature of fuel. At room temperature (20°С) resistance of the sensor should make 2300 ÷ 2700 Ohm. More exact check of serviceability of functioning of the sensor can be made by a way of its removal from the car and lowering in a vessel warmed up on fire with water. Compare results of measurements to the card of change of resistance. The faulty sensor is subject to replacement.

REPLACEMENT

 PERFORMANCE ORDER

1. Take from a tank assembly of the sensor of fuel consumption (see. Head of the Power supply system and release).
2. Remove from assembly the sensor of temperature of fuel.
3. Installation is made upside-down.
