Hi, you may be running rich. Not sure which engine you have, and this car is not sold in the US, but if you have a vacuum operated fuel pressure regulator on the fuel rail, check it for a torn diaphram.

Definition of Diagnostic Trouble Code P0420 Category: Powertrain Definition: Catalyst System Efficiency Below Threshold Bank 1Note: This definition of P0420 is applied to all manufacturers

Definition of Diagnostic Trouble Code P0430 Category: Powertrain Definition: Catalyst System Efficiency Below Threshold Bank 2Note: This definition of P0430 is applied to all manufacturers

As the code description implies the P0430 code means that the vehicle's control module has detected that the three-way catalytic converter is not working properly (is not as efficient as the factory is expecting). Replacing the oxygen (O2) sensors may sometimes fix the code, but in most cases the catalytic convert needs to be replaced to fix the problem. If the P0430 code is combined with other codes, try fixing the other codes first.

Possible causes

- EVAP canister vent control valve

- EVAP canister is saturated with water

- EVAP control system pressure sensor and the circuit

- Blocked rubber tube to EVAP canister vent control valve

- Water separator



P1448 and P0455: EVAP air leaks - Maxima Forums"Here\'s your answer:


The EVAP codes you are getting are directly related to your

\'vent control valve\'. This is VERY COMMON on this generation

Maxima. Up under yer car behind the left rear wheel is your

EVAP canister. (black plastic box) Your vent control valveis

bolted directly to this canister, with 2 screws. There should

be a vacuum line connected to it. Be sure it IS, and that it

looks like it\'s in good condition.

These valves are notorious for going bad, even more

so than the ignition coilpacks! They dont cause any

decrease in performance, but it usually decreases gas mileage,

and it will cause it to fail emissions testing. But worst of all, it

makes that MIL light on the dash flash...

It\'ll cost ya about $60 from the dealer.. have yer VIN ready..

there are 2 different ones for this generation: 1 with a nipple

and o-ring, the other with no nipple (requires separate o-ring).

Part #\'s: 14935-54u04 OR 14935-54u06

Sevice engine light is on.


Both Codes show an Emission Controls problem - very likely a large leak. Give it a really good visual and look/listen for a vacuum leak or hose off in the emmission system.
