    Greetings,

    2004 Prius, 397,000 miles.

    Car jerked when driving at around 40 mph. Then displayed the triangle and engine died.

    Scanned with Techstream. Displayed P0A90-239 and P0341 codes.

    I'm leaning toward a faulty crankshaft sensor? Am I right?

    UPDATE: It was a faulty Engine Crankshaft Position Sensor. Additionally, the plug on the one I replaced was loose.

    Onward and upward to 400K!!!
