error code 0304, 0407 and 0504
My 95 Maxima returned the error code 0304, 0407 and 0504.
I know 0304 is the Knock sensor, I'm pretty sure I can fix this myself.
But not sure about 0407 (Crankshaft Position Sensor) and 0504 (Automatic Transmission Control Unit Signal to ECU). Can anyone share your experience on how to fix these ?

0504
Diagnostic Trouble Code 0504 points to a problem with the Automatic Transmission Communications line. Pulse signals are exchanged between the Engine Control Module and the Transmission Control Module to assure smooth shifting during hard acceleration or deceleration.
This malfunction is detected when the ECM continuously receives an incorrect voltage from the TCM. Possible causes include...
- Harness or connectors (The communications line circuit between the ECM and the TCM is open or shorted.)
- TCM
- Discharged or faulty battery
