Got a 1404 code manufacturer controlled auxiliary emission controls

Hi there,

This relates to an Auxiliary Emission Control:

P0455 - Evaporative Emission Control System Purge Control Valve Circuit Shorted (or leaking)
First, check the Gas Cap is secure.

Second, check other EVAP components in the circuit.

that code is manufacturer auxiliary control emissions control

My list says code 1407 is no flow for the EGR valve.
You might want to check the valve and the sensor.

Sounds like an O2 sensor, especially if your not experienceing major problems.

Example obd code P0101
1st digit: B-Body, C-Chassis, P-Powertrain, U-Network
2nd digit: 0-SAE (generic), 1 mfg (Manufacturer Specific)
3rd digit:
* 1 Air & Fuel Metering
* 2 Air & Fuel Metering Injector Circuit
* 3 Ignition System (Including Misfire)
* 4 Auxiliary Emissions Controls
* 5 Vehicle Speed Controls And Idle Control System
* 6 Computer Output Circuit
* 7 Transmission
* 8 Transmission
4th & 5th digit - two place fault code 0-99

Well it's not a p0 code which indicates a generic trouble code, this is a code p1448 which is a manufacturers specific code, and your stands for a bad manufacturer controlled auxiliary emissions controlled component. Try checking your charcoal canister which filters fuel vapors from your gas tank, there is an evap vent control valve which can get stuck in position. You can replace that valve or try cleaning it with some carb cleaner and then using a small screwdriver to free the plunger up. Your check engine light will go off after a couple drive cycles without a fault or you can reset it iwth a code scanner.

DTC P1443 EVAP Purge Control Solenoid '2' Circuit Fault

Check the evap line and components for damage. Has a tune up ever been done?

Good luck.

Definition of error code
Evap leak detection pump pressure switch condition
Explanation

ECM detected the leak detection pump switch did change after solenoid was energized

Probable Cause
1.-Leak detection pump defective
2.-Open or shorted circuit condition
3. Solenoid defective

what you want to do is take it to nissan and scan it with the consult2 diagnostic system to tell you which of the many things in the system have failed.
the EGR is the most common.

THIS IS THE VENT CONTROL VALVE. HOPE THIS HELPS. GOOD LUCK

P0455 IS AUXILIARY EMISSION CONTROL
P1631 IS MANUFACTURE CONTROL AUXILIARY INPUTS AUXILIARY OUTPUTS
