|Upon application of take-off
power the check engine light came on indicating a P0123 TPS circuit High
output. I love my OBDII monitor. It showed me this immediately. With the
engine developing full power and plenty of runway I decided to lift-off
and see how this affected performance. During a climb from pattern to
4000' above the airport at 1300fpm temps stabilized at 195 deg f and the
TPS didn't seem to affect anything.
Once at altitude I cleared the code and refrained from applying full power for the duration of the trip. This kept the TPS code away.
After a few minutes, with everything stable, I left the airport for a short run to Newberg VOR (UBG) and back. I set the plane at 150kts and monitored the engine instruments. The temps again stabilized at around 187 deg f and the plane performed smoothly.
The flight back was uneventful.
|Upon landing I found that a
small amount of gearbox oil had run down the belly of the plane.
TPS code P0123 circuit high
|I cleaned the oil off and
removed 1.5ozs from the overflow to attempt to keep this from happening
This reduced the total gear oil to 20oz.
I also set the TPS to trigger the 5v for wide-open-throttle at precisely the time the throttle reached WOT. This equates to .63v at idle. (Note: I have the idle stop set for 1260rpm.)
