i got 21, 33, 41, 91, 94, and a couple more i cant remember
21 is ect out of range (car was cold during test) 33 is egr not opening 41 is HEGO something, running too lean?? 91 is fuel pump secondary circuit failure to pcm.. wtf does that mean? 94 is air thermactor not functional (stupid smog shit)
anyone had these codes before and what u do to fix em?
41 is an oxygen sensor code saying its reading too lean. It should say like bank 1 or bank 2 or something similar like that on the scanner depending on which one you are using. That is used to determine which one is faulty. HEGO stands for heated.exhaust.gas.oxygen sensor
ps if you are getting a lean condition. Check for possible things that would cause a lean condition like a vacuum leak or exhaust leak. If there is nothing noticeable, then check the o2's.
