hey anyone know wtf is going on i just change out my O2 sensor and the check engine light went off spent 400. on this repair. the Fing thing just turned back on 1 day later. the mech told me now i need to fix my water temp sensor coast 600. I'm i getting hosed? HELP

 

coolant temp sensor its called, whats the fault code because its important

 

service light? ill have to check into reset

 

You are totally being hosed!! The o2 is $80-120 and then takes all of 1 hour to change and thats another $60-100 in labor. Plus without codes, he is just changing things blindly. As for the coolent temp sensor, its a $20 part and takes 10mins to install. Its a very simple how to. I would first take it to autozone or some parts store and have the give you the codes it throwing. Until then, you are just spending money. I would try to recoup some of your money for the o2

 

the code is p0441 now i got the code reader and that is the only thing wrong at this point. I also got and air to fuel meter want to hook it up but where do i start. i figure i was getting hosed but i need to pass emmisions to get register. lesson learned. thank all

 

P0441 = Incorrect Purge Flow - EVAP Emission Control System

 

go here and put it in and see whatcould be wrong.The mainis the sai (secondary air injection). it could either have a hole in the plastic tubing, vac line problem to the combi valve attached to the head or the pump is dying.
