If you run 240's long enough, you'll eventually see it all.

I just isolated a particularly nasty problem in a '93 sedan - an intermittent electrical fault. After bunches of futile tests, I finally found that the ungrounded lead from the FI Coolant Temp Sensor is in fact, at times, grounded. I've traced the wiring loom from the computer to the Temp Sensor and as much as I can tell, it does not seem to have been gnawed on by some little critter.

Now, the great things about 240's is that they are so plentiful and similar that if a failure occurs in one, it is bound to have occurred in many others. Before I start butchering the wiring harness, I have to ask anyone else who has had a shorted FI Coolant Temp conductor at what point in its routing did it occur?

Thanks, one and all.
