 | This procedure applies only to analogue measuring instruments of the type. |
1. Before checking the ignition must be turned off.
2. If the meter needle is always at zero (an empty tank, a cold engine), check the corresponding fuse. If the fuse is OK, find the corresponding sensor unit (see chap. The power supply system and release of [fuel flow] or the Head of System of cooling, heating [temperature sensor]). Jumper wire, close the sensor connector to ground.
3. Briefly switch on the ignition. If there is a meter throw arrows, replace the sensor, otherwise using a jumper wire to ground terminal of the sensor on the back of the meter (if necessary, see. Wiring diagrams). | To avoid the failure of the meter does not keep the ignition on for longer than necessary. If the grounding terminal of the last meter needle will move to the maximum position, the problem is a fault condition on the circuit wiring between the meter and the sensor. If the needle will remain in the same (zero) position, check the voltage at the second terminal of the meter when a grounded first - voltage-free, otherwise replace the gauge. |
