    I've been getting code 7 recently (TPS) and my car has been running very rough. Following the diagnostic flow-chart in Helms, all of the voltages and resistances and the TPS checked out ok. Frustrated, I tried the "wiggle test" to see if I could pinpoint any loose wires while the car was running.

    When I started the car, I immediately noticed the supercharger pulley rubbing against my main electrical wiring harness. The pulley/belt had sawed through the loom/tape covering of the wiring harness and exposed a few wires inside. My guess is that a ground wire got severed, which is causing problems with my TPS (and maybe other problems that I'm not aware of yet). If I have a choice, I'd replace the engine wiring harness altogether (or a portion of it), rather than re-connect and solder the damaged wires. Does anyone know if it is possible to replace the damaged portion of the wiring harness, or should I just get out the soldering iron?

    You cannot buy a portion of the engine harness from Honda/Acura... you must either replace the entire engine harness with a new/used one or get re-acquainted with your soldering iron.

    Thanks for the quick reply, Jim. But, I was hoping you wouldn't say that.
