SOURCE: P0441 EVAP Control System Incorrect Purge Flow

Test the purge valve and the vent valve for leaks. This can only be done with a Tech 2 and or a vacuum pump.

P0441 1998 Toyota Camry - Evaporative Emission Control System Incorrect Purge Flow

When is the code detected? Pressure in charcoal canister and fuel tank does not drop during purge control (2 trip detection logic).

Possible symptoms: - Engine Light ON (or Service Engine Soon Warning Light)
- Possible a noticeable fuel odor caused by the release of fuel vapors

P0441 1998 Toyota Camry Description: The Engine Control Module (ECM) tests the Evaporative Emission (EVAP) system for the following conditions:
- Large and small leaks

- Excess vacuum

- Purge flow during non-commanded conditions

- Fuel Level and Fuel Pressure sensor faults

- EVAP Purge and Vent Valve faults

The ECM monitors the Fuel Tank Pressure sensor in order to determine the level of vacuum/pressure in the EVAP system. The ECM commands both the EVAP Purge Solenoid and the EVAP Vent Valve ON when the conditions are met in order to apply an engine vacuum to the EVAP system. The ECM commands the EVAP Purge Solenoid OFF once the system has reached a predetermined level of vacuum. This test verifies if a vacuum can be achieved in the EVAP system. Failure to develop a vacuum may be caused by a large leak or a restriction.

Possible causes - Missing Fuel cap
- Incorrect fuel filler cap used
- Fuel filler cap remains open or fails to close
- Foreign matter caught in fuel filler cap
- Incorrect fuel tank vacuum relief valve

Code p0440 code p0441 code p0446on toy echo 2000 what is the diagnosis?


P0440 Evaporative Emission Control System Malfunction P0441 Evaporative Emission Control System Incorrect Purge Flow P0446 Evaporative Emission Control System Vent Control Circuit Malfunction
  • Remove and reinstall the gas cap, clear the code, and drive for a day and see if the codes come back.
  • Inspect the EVAP system for cuts/holes in tubes/hoses
  • Inspect for damaged or disconnected hoses around the Evap purge solenoid
  • Check and/or replace the sensor
  • Check and/or replace the purge valve
  • Have a professional use a smoke machine to detect leaks

DTC P0441 - Evaporative Emission (EVAP) Control System Incorrect Purge Flow
EVAP emission canister purge is contolled by a valve which allows engine vacuum to pull stored fuel vapors from fuel tank into the engine to be burned, rather than be vented to atmosphere. A vacuum switch is used to detect when flow exists. If the PCM commands purge and sees that the switch is closed (indicating no detected purge flow) P0441 is set.
With a P0441 OBD-II trouble code, diagnosis can be tricky at times. Here are some things to try:
  • Common Chrysler fix - Replace Leak Detection Pump / LDP
  • Repair damaged EVAP lines or canister
  • Repair open or short in voltage feed circuit to Purge Solenoid
  • Repair open in PCM purge command circuit
  • Replace purge Solenoid
  • Replace vacuum switch
  • Repair restriction in Evap line or canister or soleniod
  • Repair resistance in purge connector
  • Replace PCM


DTC P1441 - Evaporative Emission (EVAP) System Flow During Non-Purge.
M
ost generally caused by a purge valve stuck open. the only way to diag for sure is with a gm tech 2 scan tool and a smoke machine. but if dont mind spending a few bucks as a good quess. Replace the purge valve.


Hope this helps.

1996 monte carlo had codes P0341, P0441, and P1655 come up. help!!!! how much work or cost is this gonna be for me?


P0341: Its a Camshaft Position Sensor (CPS) $30 to $40
P0441: Evaporative Emission Control System Incorrect Purge Flow.
P1655: Evaporative Purge Solenoid Control Circuit. $18 to $24

Looks like you have an Emission problem and if you buy the parts and put them your self, Then it will be cheaper. Good luck

I checked the codes and one comes up its po446. i dont under stand what it mean so i cant fix it to get the light to go out.


P0446 Evaporative Emission System Vent Control Circuit.
The following are descriptions of all Evaporative possible codes:

P0441 Evaporative Emission System Incorrect Purge Flow
P0442 Evaporative Emission System Leak Detected (small leak)
P0443 Evaporative Emission System Purge Control Valve Circuit
P0444 Evaporative Emission System Purge Control Valve Circuit Open
P0445 Evaporative Emission System Purge Control Valve Circuit Shorted
P0446 Evaporative Emission System Vent Control Circuit
P0447 Evaporative Emission System Vent Control Circuit Open
P0448 Evaporative Emission System Vent Control Circuit Shorted
P0449 Evaporative Emission System Vent Valve/Solenoid Circuit
P0450 Evaporative Emission System Pressure Sensor/Switch
P0451 Evaporative Emission System Pressure Sensor/Switch Range/Performance
P0452 Evaporative Emission System Pressure Sensor/Switch Low
P0453 Evaporative Emission System Pressure Sensor/Switch High
P0454 Evaporative Emission System Pressure Sensor/Switch Intermittent
P0455 Evaporative Emission System Leak Detected (large leak)
P0456 Evaporative Emission System Leak Detected (very small leak)
P0457 Evaporative Emission System Leak Detected (fuel cap loose/off)
P0458 Evaporative Emission System Purge Control Valve Circuit Low
P0459 Evaporative Emission System Purge Control Valve Circuit High
---
At least the cap isn't loose for the gas tank.

I would clear the code with an OBD-II Scanner 'erase code' button, and see how long it takes for it to come back.
