The Malfunction Indicator Lamp (MlL) indicates Diagnostic Trouble code (DTc) 16: A problem in

the Fuel Injector circuit.

The Fuel Iniectors are a solenoid-actuated constant-stroke pintle type consisting ol a solenoid, plunger needle valve and

housing. When current is applied to the solenoid coil, the valve lifts up and pressurized tuel is injected. Because the nee-

dle valve liJt and the fuel pressure are constant, the injection quantity is determined by the length of time that the valvo

is open (i.e., the duration the current is supplied to the solenoid coil). The Fuel Iniector is sealed by an O-ting and seal

ring at the top and bottom. These seals also reduce operating noise.
