    P1886 on 2003 HCH

    bought a project car. it was $500.

    engine starts, idles smooth.

    pulled the battery pack and checked all the batteries, they are solid. IMA works fine.

    A/C is cold

    all interior electrics are working.

    only issue is lack of drive. put in gear and it only revs up, D light blinks and throws P700 and P1886.
    I've looked up both, and focusing on the P1886. output speed sensor.

    DTC Troubleshooting: P1886 testing shows all normal voltages. except: i'm not sure what "Is there about 0 V or 5 V?" really means. when i connect the sensor with the meter on the pins, it drops from 5v to 0.7v Its 0.7 a valid voltage for "about 0v" or is the sensor bad?

    im going to buy the service manual soon. i have no issues with pulling and repairing a transmission.
