Service Engine light on..

[deftsound]

So yesterday I had my BBK longtube headers installed along with a spec stg2 clutch.

Well 10 miles down the road my Service engine light came on, I checked this morning to see if they had forgotten to plug in my mil eliminators since i have an O/R h pipe and it all looks good. They are right where they should be and plugged in correctly.

Any ideas as to what is causing this? Im going right now to scan the codes...

Ok heres the codes i got:

P1000 Monitor check not complete
P0135 OX S HTR CIR 152
P1131 Lack of H0251 SWT Lean

Anyone?

P0135 = Upstream Heated Oxygen Sensor Heater circuit fault - Bank No. 1.
P1131 = Lack of Upstream Heated Oxygen Sensor/Sensor Indicates Lean/Bank 1.

Ok so obviously they messed up the upper 02 sensor on bank 1.

Which side is bank 1?

just checked the passenger side and driver side upper 02 sensor and they look fine...is it possible they dropped one of them or somehow messed it up during the install?

some o2 sensors are heated so they can reach operating temperature quicker than with exhaust heat alone


when you move the o2's farther away they take longer to heatup so you end up with a heater circuit failure. why they're both on bank 1 could'nt tell you, it's usually both banks. i've heard a handheld tuner can take care of this problem

the p1000 is just a drive cycle or readiness code, once you fix the other codes this one will go away after you drive around a bit
