If the accelerator pedal position sensor doesn't jive with the throttle position sensor(s) on the TB itself, codes can be thrown or other associated good times *could* happen. Obviously these two sensors will not by in sync if you actuate the E-throttle from under the hood w/out mashing the go pedal.
I have no idea if the above still applies. I haven't owned a vehicle long enough in the past 10+ years to mess with throttle cleaning.
You might be due soon! I think our Quest had about 55 or 60k on it when I had to do a TB cleaning.
It developed a cold start issue, would start hard and sometimes not start until you applied some throttle. This was during winter.
When I cleaned the TB, you could definitely tell the throttle plate was sticking. It seemed as though the sticking was preventing the fast idle opening for a cold start.
I cleaned the TB and its been fine ever since, now about 85k.
