Attention! The vehicles covered in this manual are equipped with airbags (SRS). When performing any work near the shock sensors, steering column or instrument panel, turn off the SRS (see Airbags - general information). Do not test SRS models with any type of diagnostic equipment.
Note. This procedure applies to analog type meters only.
Fuel consumption and engine temperature meters
All checks listed below are carried out with the ignition on (key in ON position).
If the meter needle is constantly in the zero position (empty tank or cold engine), check the condition of the fuse. If the fuse is OK, find the block of the corresponding sensor (see chapter Power and exhaust systems [fuel flow sensor] or Head Cooling and heating systems [temperature sensor]). Momentarily short the sensor connector to ground. If the meter flicks, replace the sensor, otherwise use a jumper wire to ground the sensor terminal on the back of the meter (if necessary, see wiring diagrams at the end of this Chapter). If, when the last terminal is grounded, the meter arrow moves to the maximum position, the problem is a fault in the state of the wiring in the circuit section between the meter and the sensor. If the arrow stays the same (zero) position, check the second terminal of the meter for the presence of voltage on it. If there is no voltage, replace the meter.
