This is usually caused by not tightening you gas cap till it clicks 3 times try that then have the light reset and it will probably solve your problem

I have a truck that popped up a P0443 code up and I've been trying to see what it is so I can get it fixed thank yo


P0443 - Evaporative Emission Control System Purge Control Valve Circuit Malfunction

Possible causes: - Faulty Evaporative Emission (EVAP) Purge Solenoid Control
- Evaporative Emission (EVAP) Purge Solenoid Control harness is open or shorted
- Evaporative Emission (EVAP) Purge Solenoid Control circuit poor electrical connection

When is the code detected? An improper voltage signal is sent to Engine Control Module (ECM) through the valve.
Possible symptoms: - Engine Light ON (or Service Engine Soon Warning Light)
P0443 Description: The Evaporative Emission System (EVAP) canister purge volume control solenoid valve uses a ON/OFF duty to control the flow rate of fuel vapor from the EVAP canister. The EVAP canister purge volume control solenoid valve is moved by ON/OFF pulses from the Engine Control Module (ECM). The longer the ON pulse, the greater the amount of fuel vapor that will flow through the valve.

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.

Hav Check eng. Light Code PO 441 what could be the problem?


P0441 Evaporative Emission Control System Incorrect Purge Flow

This indicates that a part of the EVAP control system is no longer fuctioning correctly. The EVAP system consists of many parts, including (but not limited to) the gas cap, fuel lines, carbon canister, purge valve, and other hoses. The (EVAP) emission control system prevents the escape of fuel vapors from a vehicle's fuel system. Fuel vapors are routed by hoses to a charcoal canister for storage. Later, when the engine is running a purge control valve opens allowing intake vacuum to siphon the fuel vapors into the engine.

EVAP emission canister purge is contolled by a valve which allows engine vacuum to pull stored fuel vapors from fuel tankmag-glass_10x10.gif 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.

Likely, no symptoms will be discernible to the driver, other than the illuminated Check Engine Light.
Causes

A code P0441 could mean one or more of the following has happened:

  • Bad vacuum switch
  • Broken or damaged EVAP line or canister
  • Open in PCM purge command circuit
  • Open or short in Voltage feed circuit to Purge Solenoid
  • Faulty purge solenoid
  • Restriction in EVAP solenoid, line or canister
  • Corrosion or resistance in purge connector
  • Bad PCM
Possible Solutions

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

Engine light on Codes show 1. Po 441 evaporation emission system incorrect purge flow 2. Po442 evap emission system leak (small) 2. 446 evap emission system incorrect purse flow 2004 Toyota Tacoma pickup...


Hello! Those three codes commonly indicate the followi possibilities:

The gas cap was not sufficiently tightenend ater fueling, a bad gas-cap rubber o-ring, the vehicle had the key in the 'on', or engine running, or the tank was filed all of the way up the neck.

Any one of the abope causes will set all three codes.
