    2010 Prius base . Son was 700 miles away . Died on interstate: hybrid battery needs checked. Towed to dealership. Fuel pump failure. Had it towed to small shop: fuel pump now replaced but now reads a code for accelerator pedal and sensor. Dealership said they only read a code for fuel pump.. order the pedal.The car runs for 30 seconds then dies.Pretty sure the hybrid is going to be too low with all these non regenerative start ups. Thoughts?

    Make sure the shop tells you the actual five-character trouble code, not just what they think it "means".

    Then look for that code in this post.

    The Prius has both a throttle position sensor and a pedal position sensor, completely different parts in completely different places, and because of the way SAE standardizes trouble codes, all the trouble codes for those two different things have fortune cookies starting with the words "throttle/pedal position sensor/switch".

    If you're not paying real close attention to exactly which code(s) you have, you end up wasting time and money on the wrong part in the wrong place.
