I just got a X2 for my 99 Ranger. I have tried the 87 & 93 performance tunes doug sent me and with both have gtooen the following DTCs: P1000 (Monitor Testing Not Complete), P1132 (HO2S 11 Indicates Rich), and P1152 (Lack Of HO2S-21 Switch Indicates Rich). My question, is it a concidence that my O2 sensors went out this shortly after installing new tunes or are the three connected. Could the P1152 be causing the P1132 and in turn not allowing the Monitor test to complete? The truck has a little over 101000 miles on it and so far as I know no sensors have ben changed on it aside from rear antilock that I changed the week before last.

Fast answer would be nice I would like to have this fixed before i drive from middle GA up to WV on thursday.

Don't worry about the P1000 code. Some monitors can take weeks or months to complete under certain conditions. Until they all complete, the P1000 will be there.

Are you sure that the O2 codes aren't also there when running the factory calibration? Many O2 sensors go belly up by 100K on the odo.

If the codes only occur with the performance calibrations, you need to contact Doug for assistance. There is no way that his recals could have caused the sensors to fail. In the meantime, you can always reload the factory calibration.

 

I'm not saying that they are connected to the tunes only asking if they could be. Just suprised that it happened this soon after i installed the tuned, I think it is probably just a concidence that it happened like that. I have not reinstalled the factory programming yet, but I think I'll do that now to see what I come up with.

I have ben reading here and at RPS and everything is leaning towards bad O2s. If it is the O2 sensor which needs replacing or do the both get replaced at the same time?

Odd I just took the truck and drove arround for ~60 miles on the stock programming and the light didn't come back on, with both programs it came on atleast 10 miles before then. Guess I'll have to contact Doug then. Anyone got a phone number or AIM username for him?

 

The codes may or may not be connected to the cals. What I meant was that the cals could not have made the O2 sensors themselves fail.

Sensor 11 = PS upstream of all cats
Sensor 21 = DS upstream of all cats

 

The codes are only happening with the new tunes installed. I managed to get a line to Doug and sent him the details of my problem hopefully he will get back to me soon. I wouldn't have gone to him this quickly but I need it working thursday if at all possible.

I am still welcoming any suggestions. Maybe I should go ahead and replace the O2 sensors but I don't want to spend that much on sensors if it won't fix the problem.

 

Just got an idea, the truck is due for a tune-up so maybe the spark plugs need replacing. If they are to far worn it will alter the way the fuel burns and could affect the O2 snesors. Time to do a tune-up, I'll let you know if it helps.
