It all depends on what is wrong with it. Give us more info.
exhaust gas recirculation flow insufficient detected
Begin by removing the wiring harness. Remove the retaining screws. The emission control will come off. Reverse the process to install your new emission control.
P1495 = Manufacturer Auxiliary Emission Controls.P0171 = Bank 1 system too lean. P1584 = Manf Cntrl Vehicle Speed/Idle Speed Control Auxiliary Inputs. P1594 = Manf Cntrl Vehicle Speed/Idle Speed Control Auxiliary Inputs.
Mal function in the emission control system
The manufacturer was able to meet the tail pipe emission requirement without EGR through timing and fuel control.The manufacturer was able to meet the tail pipe emission requirement without EGR through timing and fuel control.
Trouble code P0446 means:Evaporative emission control system vent control circuit malfunction
That's why it's called spontaneous emission you cannot control it. But there is a kind of emission which is called stimulated emission emission. People use stimulated emission in lasers and it can be controlled.
I have a 2000 I30 and there is a map/diagram of the emissions control system including the EGR system on the underside of the hood placed there presumably by the manufacturer.
EVAP Emission control system leak (small). It could be as simple as a loose fuel cap.
If it is the valve on top of the fuel tank, it weel need to be replaced.
Almost all evaporative emission control canisters have a charge of wood-based, granular activated carbon. The major manufacturer is Westvaco.
