P0441 trouble code


P0441 is "small leak detected" in the EVAP system.
N80 valve that allows fuel vapors from the "canister" could be faulty.
Make sure your gas cap is fully functioning. Take it off, and take it to a local parts store that can test it.
Could be a leak almost anyplace in the system!

Hello there,my 2001 echo is lighting up trouble codes p0440 p0441 p0446; how and where should i start?


code p0440 refers to evaporative emission (EVAP) system--malfunction=== causes --hose connections --intake leak--EVAP canister purge valve
code po441 refers to EVAP --incorrect flow detected==causes the same as for po440
code po446 refers to EVAP system vent control --circuit malfunction===causes --wiring---EVAP can purge valve--ECM
generally I would replace the purge valve as it is common to all codes

P0441 Evaporative Emission Control System Incorrect Purge FlowOBD-II Trouble Code Technical Description

Evaporative Emission Control System Incorrect Purge Flow
What does that mean?

This indicates that a part of the EVAP control system is no longer functioning 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 controlled 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.
Symptoms

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 solenoid
  • Repair resistance in purge connector
  • Replace PCM

Other EVAP DTCs: P0440 - P0441 - P0442 - P0443 - P0446 - P0453 - P0455 - P0456

Diagnostics trouble codes


Could be a loose gas cap, or it was left loose once. P0441 means: p0441- evap purge system performance. In some cases disconnecting the battery over night will clear the code.
Take off the Negative cable only always wear safety glasses when working with a car battery.

Check your gas cap first make sure it is tight
