Based on information from various sensors, the ECM can
calculate the fuel amount to be injected. The fuel injector is a
solenoid-operated valve and the fuel injection amount is controlled by
length of injection time. The ECM controls each injector by grounding
the control circuit. When the ECM energizes the injector by grounding
the control circuit, the circuit voltage should be low (theoretically
0V) and the fuel is injected. When the ECM de-energizes the injector by
opening control circuit, the fuel injector is closed and circuit voltage
should momentarily peak, and then settle at system voltage.
Snow tires
If you equip your vehicle with snow tires, they should be the same size and have
the same load capacity as the original tires. Snow tires should be installed on
all four wheels; otherwise, poor ha ...
On curves
On curves, the SCC may not detect a moving vehicle in your lane, and then
your vehicle could accelerate to the set speed. Also, the vehicle speed will
rapidly slow down when the vehicle ahead ...
