SOURCE: how do you pull codes from a 98 bonneville

k, the diagnostic port is located under the dash on the driver's side. Bring the Pontiac to a parts store. They will plug a hand held scan tool into the port and 'read' any codes stored on the car's computer. This is a FREE service. Good luck.

Got a 1404 code manufacturer controlled auxiliary emission controls


This code shows up if you have a bad or clogged EGR valve, find your EGR valve if you can, clean it, this should clear the code.
If, after cleaning, code returns then you need to replace it.

Hi there,

This relates to an Auxiliary Emission Control:

I need to know what the diagnostic code PO1448 means? thank you


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.

they are all emission faults

P0453 OBD-II Trouble Code: Evaporative Emission Control Pressure Sensor High Input. P0453 code means that a reading from the engine's evaporative pressure sensor is higher than normal due to fuel tank vapor leaks into the system.

saturated carbon canister
sensor faulty
rubber evap hoses at the tank perished

idea
check the tank fuel cap seal is working
replace the cap is one possible cause

check the fuel pump pressure or for injector rail leak
P0446 Evaporative Emission Control System Vent Control Circuit Malfunction. The code P0446 is set when the engine computer recognizes a fault or restriction at the vent control part of the Evaporative emission control system (EVAP).

The Code P0452 indicates that the Evaporative Pressure Sensor is indicating pressure change values that are below specification, during the EVAP Monitor test and/or the operation of the vehicle.
