Bikeracer posted your DTC's over at InsightCentral, and here's my response:

Is this in the IRX or Superhatchy? IRX is going to have issues, being a non-native swap of an Insight powertrain into a CRX. Whenever a Check Engine light is on, I check out the codes from lowest to highest:

P0453 - fuel tank pressure sensor
P1298 - Electrical load detector circuit high voltage - this sounds like the one you want to correct today - see p 11-164
P1523 - Brake booster pressure sensor is not installed
P1542 - Heater control panel not installed
P1576 - ABS Operation Signal circuit problem - this is an IMA input. When the ABS is in operation, there will be no assist or regen.
P1649 - Motor drive module

Okay, that's not SuperHatchy. That's definately the IRX.
p 11-164 describes how to test the Electric Load Detector (ELD) and how to test the wiring going to the ELD. The manual doesn't tell me where the ELD is, but here's an interesting exhcange that mentions its location.
Your P0453 may require you to upgrade your EVAP system, but I think the rest of them can be spoofed without consequence.
