When there is a gap between angle of target and phase-control angle
degree, the valve will stop working and the ECM will trigger the P0011
code.
P0011 NISSAN - Intake Valve Timing Control Performance Bank 1
This mechanism hydraulically controls cam phases continuously with the fixed operating angle of the intake valve.
The ECM receives signals such as crankshaft position, camshaft position,
engine speed, and engine coolant temperature. Then, the ECM sends
ON/OFF pulse duty signals to the intake valve timing control solenoid
valve depending on driving status. This makes it possible to control the
shut/open timing of the intake valve to increase engine torque in
low/mid speed range and output in high-speed range.
The intake valve timing control solenoid valve changes the oil amount
and direction of flow through intake valve timing control unit or stops
oil flow. The longer pulse width advances valve angle. The shorter pulse
width retards valve angle. When ON and OFF pulse widths become equal,
the solenoid valve stops oil pressure flow to fix the intake valve angle
at the control position.
Symptoms
- Engine Light ON (or Service Engine Soon Warning Light)
- Possible engine lack/loss of power
- Posssible engine rough idle
Possible causes
- Harness or connectors
- Intake valve timing control solenoid valve circuit is open or shorted
- Intake valve timing control solenoid valve may be faulty
- Crankshaft position sensor (POS) may be faulty
- Camshaft position sensor
Tech notes
Since the Intake valve timing control solenoid valve uses oil flow to control timing, dirty oil can cause the valve to stuck open or close. Before replacing the valve, change engine oil and filter and reset engine code.

Nissan maxima code po780 2005
code p 0780 refers to gear selection--shift malfunction===causes --wiring --TR( transmission range) sensor--shift solenoids ---transmission mechanical fault
take it to an accredited auto transmission specialist shop for an exact diagnosis of the fault
I seriously doubt that you have a transmission box mechanical fault so get a second opinion if a replacement transmission is suggested
