does this code causeloss of performance i am throwing a P0140 code which is my 02 simulator. My ses light comes on for a while then goes off for a couple days then back on ...can i be losing some performance from this.It doesn't feel like it but just a little curious

Re: does this code causeloss of performance P0140 HO2S Circuit Insufficient Activity Bank 1 Sensor 2
Circuit Description
The PCM supplies a voltage of about 450 mV between the HO2S high and low signal circuits. The oxygen sensor varies the voltage over a range from about 1,000 mV when the exhaust is rich, down through about 10 mV when the exhaust is lean.
The PCM monitors and stores the heated oxygen sensor (HO2S) voltage information. The PCM evaluates the HO2S voltage samples in order to determine the amount of time the HO2S voltage was out of range. The PCM compares the stored HO2S voltage samples taken within each sample period and determines if majority of the samples are out of the operating range.
The PCM monitors the HO2S voltage and detects if the voltage goes out of the bias range. If the PCM does not detect the voltage went out of the bias range, this DTC sets.
For pete's sake, that freakin PCM wants to know everything about everything! GEEZ! Does it know when I go to the bathroom? How many times?

It does however, want to know about actual dump size as compared with average dump size. Given that data, it knows how many revolutions of paper to advance for the driver.

Re: does this code causeloss of performance Thanks for clarifying that Bearcat Steve - I was wondering how the car new to give me the correct amount of paper. <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />

Re: does this code causeloss of performance BTW, when your PCM calculates paper advance based on actual dump versus average dump, the PCM stores the calulation as a two byte integer which represents the total number of paper revolutions to advance. For example, if the number is 1, the the number of paper advance degrees is 360. Given a VERY LARGE dump, you may see a calulation as high as 50 which represents 18,000 degrees of paper advance. If the total paper advance degrees ever exceed 32,767, then the PCM sets an SES code of PA9991. Acording to Helms, PA9991, means "insufficient paper supply. Switch from Charmin to Bounty."
And now, you know the rest of the story.....
