3sx DP/TP = check engine - 3000GT/Stealth International Message Center

ChampagneR/T · 05-13-2008, 07:48 PM

So, I installed a 3sx Downpipe and test pipe and now my check engine light is on. I cleared the code at work and halfway home it came back on. I was in a hurry so i didn't pull the code, just cleared it, but i'm assuming its and O2 sensor. What can i do besides getting O2 sims. car is FED-SPEC.

car is fed spec?

wierd i thought fed specs had only two 02 sensors. If yuo got a check engine light your car should be cali spec then, or maybe you disconnected something at the same time you swapped the parts

i'll guarantee it's not cali spec, no EGR, no precat, one sensor before the test pipe. I looked under it and the wire is kinda twisted up would that affect anything.

Unless you damaged the o2 you shouldnt be getting an o2 CEL. Im Cali spec, have gutted precats, 3sx dp, test pipe, and have never gotten an o2 CEL. Never will either.

Take the few seconds to pull the code.

yeah i dont have a problem... no check engine light

Definately pull the code first, that way you have a better guess on what's wrong.

Check the actual wiring harness of the o2 sensor when you replaced it going towards the engine bay.

When I changed my DP on mine long ago, I got a CEL too. Turned out while replacing the rear 02 sensors (OBDII, 97 VR4) I pulled a little too hard and the harness popped off.

ChampagneR/T · 05-14-2008, 04:44 PM

pulled the code today and i got:

Code 11: Left front heated O2 sensor fault.

now that doesn't seem like its referring to the one under the car to me. I cleared it again it was good for the first 10 miles home then the code popped up again, and the wires go up inside the car i cant even see the harness connector.

ChampagneR/T · 05-15-2008, 02:25 PM

anybody know what sensor it's talking about, i really don't want to pull the bulb.

Stealthee · 05-15-2008, 02:39 PM

Its talking about the o2 sensor. Make sure the wiring isnt damaged.

91vr4n00maxima · 05-15-2008, 02:46 PM

you sure the car is fed spec?

if you do infact have 1 o2 sensor you damaged either the sensor or wiring when replacing the parts.
