Re: Honda 929 2000 FI Error Code 8
The TPS is on the end of the throttle bodies. Check the connector. unplug it n plug it back in, maybe clean it if it looks dirty. clear the fault codes and see if it returns.
if it does, the next thing i would do is unhook the power commander. its not uncommon for a pc to cause such problems. its the next easiest thing to do after checking the connector. just unhook the pc n plug everything up like factory, clear the codes and see if your problem is fixed. if it is then you know its to do with the pc.
after that i would follow the service manual instructions to test the throttle position sensor.
i will pm you info where to find the service manual. it has detailed instructions on testing the fault code 8
