    Diagnostic trouble codes are in the format of PXXXX (P followed by four digits)
    And can be googled for more information.

    P0136 ... O2 Sensor Circuit Malfunction Bank 1 Sensor 2
    Indicates an issue in the wiring of the downstream O2 sensor

    P0335 ... Crankshaft position sensor Circuit Malfunction
    Indicates an issue with the wiring of the crankshaft position sensor

    P0720 ... Output Speed Sensor Circuit Malfunction
    Indicates an issue with the wiring of the output speed sensor

    Since it looks like all three are wiring issues ...
    I would be looking for wires or wire bundle that has been frayed or rubbing against something
    Sometimes it is against exhaust manifold or some metal object
