The speed sensor is part of the signal for the EPS. That might give you a clue. Like ELI said, Shop manual or electrical manual is the best bet. I can't remember of anyone having trouble with the EPS.
01 MT "Little Red Rocket"
The first "TURBOCHARGED" Hybrid, Insight G1- (01/2003)
MaxIMA Battery (Serial #2), on 8/25/12 @ 301,520 miles
Use: 321,000 mi. @ 57.8 LMPG
Inspect the connector to the vehicle speed sensor. I ran into this after a transmission swap. In my case, one of the female spade connectors in the wiring harness pushed out of the housing that plugs into the VSS. This caused a loss of speed info, which the Insight needs to determine how much steering assist to deliver. I pushed it back in and reconnected it, which cured my EPS light. In your case, if the sensor has not been recently disturbed, corrosion or wiring damage could be the issue. HTH.
Not to hijack the thread, but considering I'm having the same problem (EPS light and no power steering,) I figured I'd chime in. No sense starting a new thread for the same problem.
Shorted mine on the obd2 port per Mike D's instructions and and got EPS code 17. Opened my service manual, and it says I need the PGM to clear? I tried leaving it shorted and followed the manual's instructions to erase (with no PGM,) to no avail. Any other way to to clear the codes to see if it comes back on or if it does the trick?
Just my 2 cents. I had the EPS light on, no power steering, no blown/removed fuse. Ended up being the EPS module, located inside the car, passenger foot area, on the right side. Picked up a used one on Ebay for $40, took care of the problem.
