DTC P0441 EVAPORATIVE EMISSION CONTROL SYSTEM INCORRECT PURGE FLOW

I had the same problem with the Evap code and I found out today that it was only the gas cap. I was getting both reading from a gas cap. I bought 2 gas caps from O'Riely and Autozone and neither one solved the problem because the caps were cheap. So, my mechanic got me one from Napa or the dealership, runs around $13-$23 and it solved the problem. The check engine light is off and to make sure, the mechanic drove my car for a while and I drove my car about 70 miles and the light did not come back on. Please do not waste your money on O'Riely and Autozone gas caps. Also be sure to replace the gas cap before doing any other major stuff. My car was a maze up until today.

It may not reset for 50 drive cycles. It would be quicker to get it scanned by the dealer who just sold it to you and ask them for the code. If it does come back as a small evap leak then they can clear the code and you can be on your way. If the vehicle was left running during you refilling the fuel, it would trigger this code. Just don't tell them that when you take it in. Play dumb and tell them "it just came on"! let me know if you need anything else.

po441 emissions code for a 2000 Avalon - just wondering some possibilities on what it might be and what it will cost.
This indicates that a part of the EVAP control system is no longer functioning correctly.

FIRST, call the local Toyota dealer, tell them the error and your mileage. It MAY be covered under warranty as part of the emissions system, which many manufacturers have extended warranty programs on at no cost to you.

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

With a P0441 OBD-II trouble code, diagnosis can be tricky at times. Here are some things to try:
  • 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
