egr ports

[laloquera]

Just got done doing the egr port cleaning job, its like the third time I've done it. But, my check engine light came on, and threw error code 41. Did I miss something. Clear out the tcu twice and got the same code. Im gonna be tick off if I need to back in there. Shit! help help.

41 is the oxygen sensor. It has nothing to do with the EGR ports.

Replace the sensor with an NTK or Denso unit. Do not use Bosch.

4real? I got four long flashes and one short blink at the end. Am I reading it right, 40 or 41? Is there a place in here, so I can look up the code and clarify it? Thanx

Crap, forgot to mention that I had to drop the entire exhause pipe to remove some rusty ass bolts to replace the muffler. Took it off at the exhaust manifold, I did not touch the 02 sensor, my o rings look in good, so I kept them in. Would a possible exhaust leak register a 40 or 41 error code?

No. Replace your o2 sensor. Trust me.

Or at least make sure you hooked everything back up properly.

deevergote, thanx! I did disconect my 02 but only to take off the heat shield to spray paint it. I was in a hurry putting back together, but will double check everything tomorrow.

the exhaust leak before the o2 would have to be totally severe to set off a 43, not a 41...i believe a 41 is a heater circuit for the o2.

Huh ? What O rings ?

[laloquera]

Its a 41 not a 43. Im good with that clarification. O ring? I meant O ring gasket that are found between exhaust piping where u bolt them together.

Like wede said 41 is o2 heater so like deev said replace it with ngk/ntk or denso

[laloquera]

thanx, i will try swap o2 sensor tomorrow

[laloquera]

K, Im back and still dealing with this issue. Swap out O2 sensor, and still throwing code.
Im thinking of poping out the egr ports again. I gotta feeling Im missing somethig or did not clean everything out. How do get those egr cap plugs off, the ones you get from the stealership? Drill & tapp out also?

After you swapped the o2 sensor, did you reset the ecu by pulling the backup/radio fuse or disconnecting the battery for 5-10 minutes? Otherwise the code your seeing is what is stored from when your old o2 sensor was bad.

egr ports has nothing to do with a heater circuit. id say check wiring and connection.
