Note. This procedure applies to analog type meters only.
1. Before starting the test, the ignition must be turned off.
2. If the meter needle is constantly in the zero position (empty tank or cold engine), check the condition of the appropriate 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, heating systems [temperature sensor]). Use a jumper wire to connect the sensor connector to ground.
3. Briefly turn on the ignition. If the meter flicks, replace the sensor, otherwise use a jumper wire to ground the sensor terminal on the back of the meter (see wiring diagrams if necessary).
Note. To avoid damage to the meter, do not keep the ignition on longer than is really necessary. 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 voltage at the second terminal of the meter when the first one is grounded, - there should be no voltage, otherwise replace the meter.
