A hole in the exhaust manifold can lead to an evaporative emissions (EVAP) code, but it’s not a direct cause. The hole can create a vacuum leak or alter exhaust flow, which may affect the vehicle's overall emissions system and trigger codes related to EVAP system performance. Additionally, it may cause issues with the oxygen sensors, further complicating emissions readings. It’s essential to address any exhaust leaks to ensure proper functioning of the vehicle’s emissions systems.
i think the code p1400 means exhaust gas recirculation(EGR) system/ evaporative emission(EVAP)system- valve mulfunction i think the code p1400 means exhaust gas recirculation(EGR) system/ evaporative emission(EVAP)system- valve mulfunction i think the code p1400 means exhaust gas recirculation(EGR) system/ evaporative emission(EVAP)system- valve mulfunction
no
It could cause a failure. The line could be collapsing, causing no flow through it. This would cause a fail code.
Not likely.
The Evaporative Emission Control System monitors the fuel vapor flow between the engine intake manifold and the EVAP canister. The system failure occurs when a leak or blockage between the intake manifold, the EVAP canister purge valve and the EVAP canister is detected by the PCM. Code P1443 Possible Causes: - Pinched, blocked or plugged fuel vapor tubes/hoses (except between fuel tank and EVAP canister) - Damaged EVAP canister - Disconnected, cracked or cut fuel vapor tubes/hoses (except between fuel tank and EVAP canister) - Damaged EVAP canister purge valve
Trouble code P0446 means: EVAP Vent System Performance
Trouble code P0449 means: EVAP Vent Solenoid Control Circuit Malfunction
All newer cars have a Evap system, the function of the system is to re-circulate gas and exhaust fumes so they dont vent into the atmosphere.
The EVAP purge solenoid on a 2001 Nissan Sentra GXE is under the hood. It is mounted to the top of the intake manifold.
On a 2.2 its on the backside of the engine below the intake manifold......
The above is copied and pasted from "The Thunderbird And Cougar Owners Club of America" "Straight from the service CD (mostly, I added a descriptor after the code) P1443=A problem with the EVAP purge flow system Continuous Memory Diagnostic Trouble Code (DTC) P1443 indicates an incorrect evaporative system purge control valve flow. Possible causes: -- Obstructed, open or cracked hoses between EVAP canister purge valve and intake manifold. -- Damaged EVAP canister purge valve. -- Damaged PF sensor."
This code indicates an incorrect Evaporative System Purge Control Valve flow. Can be caused by clogged, disconnected, or broken vacuum line between the EVAP Canister Purge Valve and intake manifold or bad Purge Valve itself.
