Finding a suspected electrical fault almost requires the use of one. You have a circuit that is inaccessible, for the most part, other that the terminals at each end. It is quite possible that you have a break in the wiring, that could be inside the insulation, the wire would look fine to the naked eye. You could also have loose terminal tension at one end or the other that could cause a symptom like you are describing. If you replaced the sensor, and the fault still exists, the only other component in the system is the powertrain control module. I would not recommend replacing it, until you rule out the circuitry. The only possibility of ruling it out, without test equipment, would be to run new wires for the circuit. And even then, your talking about terminals and connectors that require proper disassembly and reassembly procedures.
