Anyone have the specs on the resistor that is used on the 74, 2.0 head temp sensor? I have a lean condition and need the sensor....how many ohms?

go buy a POT and put it inline. one that goes from 0-1000 ohm..
set, test, set, test...when its right, remove the POT and measure it with an ohm meter, then go buy the right resistor. Both can be had at radio shack. Rich |

Both can be had at radio shack. Rich (IMG:style_emoticons/default/agree.gif) I have a 73 with the the 270 ohm resistor. My FI is almost completely refurbed. When I got it running, it had the lean idle hunt. I went to the Shack and got a variable resistor 0-1000 ohm and replaced my 270 ohm with it. I dialed it up until the lean idle hunt went away. I wound up at 480ohms I think. I also checked this on an exhaust gas analyzer, and I passed AZ emissions with this setup. So, I know it worked for me. It may not be your problem, but for $3 or whatever the variable resistor costs, its an easy try. |
