P1000 came up as an DTC
 

does anyone know what this means? the description is monitor testing incomplete.

i dunno if it was there when the test tune from fred was on there but when i returned it to stock it came up on the SCT i have but not my ultragauge.

does anyone know what it is?

One or more of the OBDII Diagnostic Monitors has not yet cleared. This is usually due the fact that driving conditions have not been correct to allow a monitor tor run to completion. Try driving some more and recheck.

Do not reset the PCM memory - every time you do, the monitors will also be reset and will need to run again. The recent switch back to the stock tune is what caused the current P1000.

Thanks. If I switch tunes, do I have to go from 87 to stock to 91 or can I just go from one tho the other?

100% Correct. Are you a tech?

Aside from my switching tunes question, I have another. If I changed my tire size on the test tune, changed to stock then put another tune would I have to re input my new tire size?

I have the same code. I cleared the code and drove 70+ miles to reset the computer, the light stayed off for the rest of the day but when I drove home from work it came back. WTF am I doing wrong?

oh yeah its a 3.0. I didn't wanna start a new thread to ask the same question.

Do you have some kind of SCT or Tune put in it?

No sir well not that I know of. I bought it used.

Any ideas?

I have to set the i/m monitors at work all the time.We cant smog used cars unless 4 out of 5 are set.Im not sure if the steps are the same on fords as chevys.If you need help let me know ill look up the steps for you.

No. Bob is not a tech. Bob is a genius.
