Help! Code 293 after plug-in conversion

After completing plug-in conversion (plug-in supply) on 06 Prius:
Car operated normally in all modes inititially.
After about 10 miles, car would only operate in ev only mode.
Check engine light on when trying to start with on button and car will not go into gear.
The following morning:
Engine started on start up.
Conditions appear normal
After warmup, check eng light on, car will not go into gear.
On shutdown, on button is orange, dash displays flashing boxes where PRNDL would normally be.
Pulled code U293 - Inverter current sensor malfunction when inverter in fail-safe mode.
Stuck in Petaluma until problem fixed.
Plug-in Supply folks very cooperative. Company works with customers

I know it is too late to change your choice, but why did you do Plug In Supply instead of Hymotion?

i think because of price!

I have the 10 Kw lithium pluginsupply system and have never has that problem. I've only been driving 24-30 miles each day for 4 months in all electric mode. It is perfect.

It cost less than trading a 201 that only gets 51 mpg. I go totally electric. We finally had to buy some gas after 3 months for a longer trip.

I wonder whether EVron ever made it back to Portland?

I would also be curious about how this problem was resolved

Did you ever get this issue resolved?
