Not long ago I was trying to adjust the idle speed on my 240 and happened to ground the pink wire which is the lambda test lead. Recently, I noticed a post by Mr. Stickbuilder saying that if the pink lead was grounded the O2 sensor would be destroyed. I tested the O2 sensor today and got a reading that ranged between .82 and .85 volts. Not much fluctuation occured at all as I tried to create various vacuum leaks. The car was nice and warm for the test also. Did I ruin the O2? Has anyone else done the same to their car?
