I removed my glow plug #4, and although I was able to remove the plug, the tip (the part that glows) of the plug stayed inside the motor. I realized this when I inserted the new plug, and it wouldn't go in far enough to reach the threads. I'm now getting a P0674 code for a faulty glow plug. I don't care about the plug, as the motor starts with no issues. What I would like to do is fool the diagnostics into thinking the plug is okay, so my dashboard light goes off. I measured the resistance of a good glow plug, and it is 2 ohms. I'm figuring I could put a resistor across the plug wires to fool it. Does anyone know if this would work? What size and wattage resistor should be used? Is there another method to accomplish this, such as programming?
