Code P0441 I am getting a P0441 code on my 2.7L 2003 intrepid..I have also received a P0153 and P0300 code....both have cleared and the only one remaining is the P0441...Where should I start to look..I have tried the the gas tank cover already , so what now

code p0129 refers to barometric pressure-two low===causes wiring---BARO sensor, ---mechanical fault
code p0441 refers to evaporative emission (EVAP) system--incorrect flow detected=== causes ---hose connection/s---intake leak--EVAP canister purge valve

replace the BARO sensor and the purge valve after seeing that the filler cap is on correctly.

get new gas cap it will give a p0441 code!!!

Kevin, It sounds like you have several things going on. You first code P0770 did not pull up on my database,. The P0441 is for an evaporative leak in your fuel purge system. Vapors are continually pulled from the fuel tank on later model fuel injected vehicles. A leak in this system such as a damaged hose, loose gas cap, etc.. can trigger one of these codes.

Your last 2 codes are relating to a transmission solenoid fault. Hopefully, this will head you in the right direction.. Best of luck..

A code P0300 may mean that one or more of the following has happened:

• Faulty spark plugs or wires
• Faulty coil (pack)
• Faulty oxygen sensor(s)
• Faulty fuel injector(s)
• Burned exhaust valve
• Faulty catalytic converter(s)
• Stuck/blocked EGR valve / passages
• Faulty camshaft position sensor
• 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
  Defective computer

It appears that there is a problem with your #4 cylinder. either no spark, or fuel. The other problem you have is with your EVAP system. Have you driven with your gas cap off or loose?

EOBD AND ISO CODE P0441 IS EVAPORATIVE EMMISSION SYSTEM INCCORRECT PURGE FLOW

Most common problem causing this code is the purge solenoid. A quick smoke test will show if you have any leaks in the system. If no leaks and the fuel cap is installed properly it's the purge solenoid.

Hi
code P0068 = MAF/MAP sensorthrottle position correlation
code P0108 = MAP/BARO circuit high input
code P0441 = EVAP emission control system purge flow fault
take it infor a service
cheers Rob.

P0152 is o2 sensor 2/1 voltage high. Sensor 2/1 is your right bank upstream o2 sensor located in the manifold. Make sure it is pluged in.
