    Grid Heater Light On While Driving

     

    If you happen to notice your grid heater light is on while your driving this is a sign of injector failure. The ECM has the ability to detect excessive return flow from the injectors. Grid heater light is a warning to the owner that the injectors are worn out and all six injectors should be replaced very soon.
