Front and Rear O2 Sensors

Front and Rear O2 Sensors
The DTCs for my 2007 Springer with the 103 kit are: P132-0 and P152-0 indicating Front O2 Sensor High and Rear O2 Sensor High, respectively. My local dealer wants to spend an hour on diagnosis, at the cost of $90.
Because I don't have HD service manuals, and prefer not to spend this kind of money simply to diagnose a problem, I wonder if anyone has a series of steps I can take to possibly identify the cause of these DTC codes.
I don't want to remove and replace the O2 sensors without knowing the cause of these codes and the reason my bike simply stopped running while I was riding ... the symptom is similar to a fuel vapor lock but after coasting to a stop and powering off/on, the bike ran again.
I have some basic hardware tools (wrenches, sockets, etc.) but no diagnosis tools.
Thanks for any and all help.

O2 sensors reading high indicates a lean condition. You'll need a service manual and some basic knowledge of EFI to nail down the cause. Could be a problem with the fuel pump, could be the TPS. could be the MAP sensor.
A fuel pressure gauge is fairly cheap, the TPS can be tested with an ohm meter.
