Fuel consumption detector (YW1159)

Installation

1、Wiring Diagram

2、How to connect

3、Please check before instillation

1） Check whether the car original oil detector system working normal or not; when ACC is ON, car original oil detector system working well and the oil meter fix on the current oil level. Please note down the current oil level value.

2） Check the fuel gauge float is variable resistance fuel level sensor; Disconnect the car power, using the resistance profile of multi-meter to check whether the fuel float has the normal resistance( normally, it 5~500 Ω),few car use Voltage type oil float which are not suitable for this product.

4、Steps

1) Take apart of dash board carefully and find out the oil meter signal line.

2) Oil meter signal line voltage；Using the voltage profile of multi-meter measuring signal line for power supply voltage(1~5V)

• Oil meter signal line is connect to the fuel float signal line; Disconnect the power, connect the fuel float signal line with one side of the multi-meter conduction and oil meter signal line connect to another side of multi-meter, if  connected, than that must be the oil tank signal line.
• Cut off Oil meter signal line, oil meter needle will come up to the top or bottom suddenly. If not, please find again for the right oil meter signal line.
