P0122 is throttle position sensor
P0441 is incorrect purge flow in the evaporative emission control system----- the purge valve is probably bad.

Code P0441 is the purge solenoid. Examine the fuel system to make sure none of the vapor hoses are cracked or leaking. If the hoses and all connections are as they should be you'll need to replace that purge solenoid.

P0122 is the APPS sensor: The Accelerator Pedal Position Sensor (APPS) is a linear potentiometer. It provides the Engine Control Module (ECM) with a DC voltage signal proportional to the angle, or position of the accelerator pedal. This used to be referred to as the Throttle Position Sensor (TPS). You'll need to check the connections at the sensor and most likely replace.

I paid a shop to replace break line in 1997 dodge caravan. They lowered gas tank to do the job. Now vapor code and check engine light keeps going on. Shop cannot find problem and has even charged me to find and replace rubber connector in system that did not work. I believe they are avoiding dropping the tank to see.
any ideas

I'm receiving an Error code po441, I took it to the dealer who replaced the EGR valve and reset the engine light and cleared codes a week ago, now my engine light just came back on with same code


Some dealer you got there

PO441-EVAP System --Incorrect Purge Flow

They may have found an EGR Valve issue,
but they certainly blew off the EVAP Code

I would guess you have a bad EVAP Canister
Purge Valve or some other purge control

if the air filter was recently inspected or changed, look for the vacuum hose to be disconnected from the valve located on the air filter cover. another source may be the gas cap either loose or with the tether strap caught under it preventing a proper seal
