What would be giving my Maxima the error code P1273 and what would be the part name?

Question

What part needs to be replaced for the error code p1273 in my 2004 Nissan Maxima?

Answer 1

Depends what the problem is, could be an intake leak, dirty air flow meter, bank 1 sensor 1 air to fuel ratio sensor.

Possible causes

- Faulty Air fuel ratio (A/F) sensor 1 Bank 1 

- Faulty Air fuel ratio (A/F) sensor 1 heater Bank 1 

- Fuel pressure

- Faulty Fuel injector 

- Intake air leaks

- Faulty Air Flow Meter

 

clean the mass air flow sensor with mass air flow sensor cleaner and disconnect the battery for 30min or so to clear the computer if the code comes back other things need to be checked.
