Hyundai Santa Fe
On the 2003 Hyundai Santa Fe with the 3.5L engine, the P0441 points to a problem with the EVAP Purge Control System. There are a couple of things to check here. First, Check the underside of the fuel cap for any cracks or signs of defects that may keep the cap from sealing correctly. If there are any doubts about the inspection of the cap, replace it. Keep in mind, you will need a cap that meets OE Specs. Those “universal” or “locking” fuel caps sold at after market parts stores do not meet OE specs, and will not seal the system correctly. If you are certain the cap is good, next the EVAP (emissions control/recovery) System should be “smoked” to check for any leaks. This is where a machine forces smoke through the EVAP system and any leaks can then be more easily found and repaired. If the smoke test proves no leaks, then the problem will lie in the Purge Control Solenoid Valve (PCSV). These are actually fairly common fail items on these vehicles. It’s mounted under the hood on the top, rear, driver’s side of the engine. Inspect the electrical connector and wire harness for any loose, broken or damaged wires. If no problems are found, replacing the Purge Control Solenoid Valve (PCSV) should solve the P0441.
