I've had it, I want it fixed. Someone can help me. I'm getting code 17 on my check engine light. 1 long, 7 short flashes. I was told it was an o2 sensor. Well, I replaced it and my car still wants to bog at light throttle. It only does it when the car is warmed up. When the car is cold, I have no problems. Can someone tell me what to fix or replace? PLEASE....... HELP!

 

man, who did I **** off? nobody can help?

 

does the code still exist after you reset the ECU and with the new O2?

Check the grounding wires that connect to engine and underneath the car that connect from body to CAT.

I would replace these or add the grounding wires.
Sometimes, after you put in new O2, it is better to reset the ECU, so it will learn the new O2 measurement, otherwise it will run from the old memory.

I know this thread is ancient but I am havin the exact problem he was. My o2 isnt all that old, i say about a year or so. Anyway it threw the same code, 17, for "feedback system" and i guess this pertains to the o2. But there is another code for the o2, code 15. Can anyone help?

 

anyone?

 

IF you have a PFC and get slight hesitations under light throttle/cruise situation, I have found it necessary to turn off o2 sensor input in the PFC "etc" menu.

IF you have a stock computer (I assume so, or the code would not show up to begin with) then you either have a bad sensor, a bad connection, or a bad ground. One time I had a car with everything else being perfect that kept kicking the code, so I eventually dicked around and actually ran a ground wire to the o2 sensor itself, kinda wrapping it around the sensor between the washer and threads. Then tightened it down and made sure the other end of the ground wire was clean and tight onto the battery terminal. From then on I never got the code again.

I have heard of guys that tried the generic bosch replacements that you splice plugs on, which would never work, and the code was cured with an actual NGK/NTK or Denso sensor.

Recently I had this problem on a car that was burning oil, and as soon as the oil burning issue was resolved the code did not return. Same sensor, grounding, etc.

 

Thanks I will try that
