: P1860... Problem

10-29-06, 09:29 PM
Okay, I am having a problem. I have a 2001 STS. I just drove from South Carolina to New York, and suddenly my car is making a strange noise. It's sort of hard to explain... Not really a grinding...but I can't really think of another word for it. It almost sounds like a loud exhaust, but it isn't.

I know that really doesn't help much. The sound grows louder the faster I drive. It also seems slightly louder when the car is going straight (rather than turning).

Anyways, this happened during my trip. Now the car is also showing P1860: TCC PWM Solenoid Circuit Electrical ?

1.) Is this a serious problem? The performance of the car didn't seem to be affected.
2.) Will I be able to get back to South Carolina, or do I need to get this fixed right away?

Even the slightest bit of help is greatly appreciated... thanks.

You may have 2 different problems as I cannot imagine the TCC solenoid making any noise if it fails.
