    Hello, I have a 2001 Prius Hybrid. and have no clue where to start with these codes. The car will start and idle but when I put it in gear I have No acceleration with the gas pedal at all. Sometime the rpms will ramp up and down. I checked the codes and I have 6 codes
    P1430
    P1636
    P3106
    P3120
    P3125
    P3002.

    Please help me with this. I am in dire straits as it is and now this.
    Thank you in advance..

    P1430 is a vacuum sensor code. Doesn't sound like it matches the symptoms, so I'm guessing it's symptom, not a cause.
    P1636 says it's HV ECU or Engine ECU This could be the cause, maybe.
    P3106 is ECM communication circuit. Could be cause or symptom
    P3120 is transaxle malfunction.
    P3125 is converter and Inverter malfunction

    I can't find a reference for p3002, but it sounds like the first thing to check is the ECUs, if you can find a known good to swap it out.
