Ok I took my 1.4 ej9 for its MOT today, never got a single advisory but failed on emissions I am trying to figue this out without spending to much so heres whats happened on the lead up to the MOT:
4 weeks ago, EM light came on & stayed on for over 24 hours (no noticeable difference in engine performance) I then plugged in my diagnostic reader and got a generic code p0138 "02 oxygen sensor circuit high voltage (bank 1, sensor 2)"
I cleared the code and it did not return although i did get a bit of rev dipping for a day afterwards like the idle air control valve was dirty however this stopped pretty quickly. Since then nothing has been out of the ordinary until today when it failed on emissions,
Here are the results from the test:
FAST IDLE
ENGINE SPEED 3000 2670 PASS
CO 0.30 0.83 FAIL
HO 200 36 PASS
LAMBDA 1.030 1.009 PASS
SECOND FAST IDLE TEST
ENGINE SPEED 3000 2680 PASS
CO 0.30 0.71 FAIL
HO 200 19 PASS
LAMBDA 1.030 1.001 PASS
IDLE TEST
ENGINE SPEED 900 740 PASS
CO 0.50 0.04 PASS
Sorry if thats hard to read, any help would be much appreciated Thanks!
