I don't know the name of it but it has a elect plug on it with a 90* turn vacuum line on one side and a clamped vacuum line on the other it is located under hood drivers side next to shock tower
replace that,,, P0444 gone and car will run better. jim

edit: i assumed you changed the RCM and you still had po444 , thanks Mark sometime i assume too much...

P0141 is the heater trouble code for bank 1, sensor 2.
P0444 is an indication of evap issues.

The common thing between them is they are both powered by pin E5 from the RCM. I'd suggest putting your spare RCM in and seeing what you have after that. If this person is one who still has no spare RCM, they should order one today.

OR, they could waste tons of time and money 'troubleshooting'.... Owner's choice. But I hate wasting time, so I have a spare RCM.
