Seems to me i read a post that after the power train pcm reset (hybrid), their mileage was adversely affected…..was i dreaming?

I think what happens is that after the reset is done, it takes a while for the miles to empty calculation to catch up. When mine was done, my miles to empty showed a big decline, but as I drove it more, it began to get back to normal. By the time I needed gas, my mileage was in line with all my other fill-ups under similar conditions. It just appears to affect the mileage when first done.
