Other than short to ground, what is the physical effect of B+? Such as I'm getting a code for exhaust gas temperature sensor B+. And my car sounds like it isn't quite running up to par. Now I'm not a novice to this car, but just not sure since this is my first B+ code. I've had several short to grounds, but after clearing code the problem would go away for months at a time.

Additional Info: The car has been sitting for a few weeks because I just changed the timing belt and all the seals you can think of on this engine, minus headgasket. Could the absence of running the car cause some sort of buildup that will go away in time...even though I doubt this would be the case since these cars are NEVER simple.

 

It just means there is a short or short to ground on the positive + wire to the EGT sensor. It doesn't matter really, a short to ground on the negative or signal wire would have the same effect. It can also mean the internal resistance inside the sensor is shorted which is 90% of the time the case. Change that EGT sensor and the code will cease to exist. You will also might notice a decrease in fuel mileage with that fault code present.
