I just got my digimoto tonight and I was finally able to check why my SES was on. I was assuming it was cause I was running rich, but it threw a bunch of other codes.

0123 - Throttle position sensor/switch a circuit high input
0138 - Rear O2S, Bank 1 Maximum Voltage Monitoring
0172 - System too rich bank 1
0175 - System too rich bank 2
1122 - Throttle position sensor and MAF sensor not match
1148 - Closed Loop, Bank 1
2135 - Throttle Position Sensor

Other than the 2 rich codes what do they mean? Better yet how what do I look for?

 

I'm guessing that the 1122-Throttle Pos sensor and MAF thing is because the MAF isnt' even functioning at this point, with your vpro. The others, no clue.

I'm afraid to have my codes checked

 

Chris,

never mind. just read your entire post.

 

I was throwing the usual misfire code, and some cam sensor code. That was before the vpro, so I'm not sure if there are any new ones yet. Like I said, I'm almost afraid to have them checked. I just want to drive it, not worry more, haha.

 

The weird thing is I was able to clear them after the V-Pro install and I didn't have any for a while until I started running rich. I check my injector o rings and no leaks coming from there.

 

Jorge, I am not throwing any of these codes, just the usual misfire and the occassional tto rich code. None of these appear to be a "problem" code. I clear and check my codes almost evey day. Remember if the codes have been building for awhile, they may be just random occurences. Keep an eye out for recurring codes. Here is my initial feedback:

0123 - Throttle position sensor/switch a circuit high input - might need to readjust throttle position. Nissan can do this.
0138 - Rear O2S, Bank 1 Maximum Voltage Monitoring - no worries on this one.
0172 - System too rich bank 1 - better rich than lean, no big deal.
0175 - System too rich bank 2 - same as above.
1122 - Throttle position sensor and MAF sensor not match - and never will .
1148 - Closed Loop, Bank 1 - ??? Not sure about this one.
2135 - Throttle Position Sensor - again, may want to have Nissan reset the throttle position.

 

damn, no way to go in with the hks fcon and eliminate those suckers?

 

Not that I know of.

 

my car hasnt throwin any codes yet with the fcon, but im not fully built.
