P0328 SUBARU -

Question

I have problems with P0328 and P0456 sensor codes. I own a 2001 Subaru Forester and a few months ago the check engine light came on. About three weeks ago, when I depressed the gas pedal from the stop position, the vehicle would SLOWLY gain momentum i.e. it would stay at 20 mph for about ten seconds or so before achieving higher speeds. I took the vehicle for a diagnostic and that\'s when I was told about the two sensors. Earlier this week I made two round trips that averaged 180 miles per day. When I turned on the ignition to return home on the second day, I noticed the car sounded slightly strange. Fortunately I was able to get home safely. The next day the sound was still there but I was able to drive; relatives dropped me off to do some errands and they returned home. But when they attempted to turn the car on a couple of hours later, it would not turn over. When I got home, I tried to start the Forester but it wouldn\'t turn over for me either.

Could problems triggered by the P0328 and or P0456 prevent my SUV from starting?
