I just get a new NGK o2 and the car still say code 41...i reset the ecu will the unpluged battery.

I try a another one...and still the same stupid problem...


My dyno guy said to me thats is maybe the heater in the O2 BUT i tried 2 different one so,im [freak]ed.


maybe the wiring but last week everything was perfect except the TPS that i change 2day.


PLEASE SOMEONE HELP ME!!! dyno is tomorrow and i really want to see my over 200whp this time.


BIG THANKS

 

Check to see if the O2 heater wires have continuity.

 

on the connector side ? and the plug in seem to be OK, nothing wrong there, the wire is perfect in the plug...well i will re-check in 30min


thx !

 

Isn't 41 "ineffeciant Catalyst"?

May not be the actual O2 sensor...

For OBD-1, that is primary oxygen heater.

Lol

 

so its just need to be warm up?

 

Are you getting tuned or just doing a few pulls?

 

full tuning, i dont really need the o2 for the tune because they use his o2 to tune it but for back home i want my car run with no check engine

Relax, they can disable it, and u can run closed loop anyway, i do, have them tune partial throttle and u have no problems, you can disable all that nonsense.

 

thx man, yeah i know, im all stress about that, i've been working on that setup like one month and i hate to have some lil prob at last time like that

 

well the motor throw 204whp and 143wtq with a lot of trouble...i need to get back to OEM ignition, msd is not that good that i was thinking and i forget the put my timing cover back so the guys was not able to play with my timing and cam gear, they set to 0degres...well in 2week i go back there with a ready motor this time.

 

Good numbers w/o dialing the gears in.. and ya, msd is fail.. oem ftw

 

Samething happend to me. I replaced o2 sensor for no reason, but it turned out that the wire from the ecu harness fell out of the plug.. I'm assuming my friend had his foot all over the wire harness since my ecu is always throw on the floor and not tucked away.

 

pull on the 4 gear...the engine pull great, no traction in first gear in the street....but without the cam gear touched, the toda spec B feel like ctr cam lol, they set to 0degres :/ so in 1-2 week re-tune time.
