On a YJ 258, there is a sensor that goes into the block toward the back by the firewall that has a green wire with thick black stripes on it. Can anyone tell me what this sensor is and what it does? I have a Howell TBI on my 258 and realized today that this wire and sensor are not connected to anything and sense that it might be why my engine keeps flooding. Anyone know? Thanks.
Which side and are you sure it isn't in the head becaue the only sensore I can think of that is that far back is the temperature sending unit(in the head way back on the drivers side. It could also be the oil sending unit(pasanger side middway on the block. I would go out and check for you but its to dark. Sorry
That's the thermostat for the intake heater.
It's an electric heater under the carb. That helps vaporize the fuel mixture before the engine reaches temp.
It opens, turning off the heater at 160 degrees.
The sensor he's talking about is in the water jacket of the intake manifold, I doubt an O2 sensor would even fit, and wouldn't last long if it did /wwwthreads_images/icons/smile.gif
