P1778 Nissan -

Question

have a 04 murano i got these 3 codes. p0746; p1700; p1778
what does this mean

Answer 1

P0746 is for pressure sensor A which is inside the valve body

P1778 is the step motor (the transmission needs to be replaced if the step motor is bad)

The transmission might be bad NISSAN has extended the warranty to 10 years/120,000 miles, whichever comes first. Call a local dealer to see if you are covered under warranty if the car is a last model 2004 you should still be under warranty

if you are not under warranty I would try to replace the fluid before spending money on a new or used transmission (if you are going to have someone besides the dealer install the transmission flush the transmission lines before installing the new one)

good luck
