hello all, I just bought this 2000 M6 z28 and I have a few codes (not CEL codes) that i pulled up with my friends OBD2 reader made by CENTECH, i would like to know if ANY of these readings look out of the ordinary. The person i bought the car from told me that everything is pretty much stock, except for the flowmasters.


these readings are when the car is off, on accessory mode

DTC_CNT: 0
FUELSYS1: CL
FUELSYS2: CL
LOAD_PCT: 0.0
ETC: 198
SHRTFT1: 0.0
LONGFT1: 7.0
SHRTFT2: 0.0
LONGFT2: 9.4
MAP: 30.1
RPM:0
VSS: 0
SPARK ADV: 0
IAT: 0.000
TP: 0.0
AIR_STAT: OFF
02B1S1: 0.045
SHRTFTB1S1: 0.0
02B1S2: 0.025
02B2S1: 0.015


I even got codes from when the car is on in neutral position

DTC_CNT: 0
FUELSYS1: CL
FUELSYS2: CL
LOAD_PCT: 2.0
ETC: 188
SHRTFT1: 2.3 - 3.1
LONGFT1: 10.2
SHRTFT2: 0.0 - 3.1
LONGFT2: 14.1
MAP: 8.9
RPM: 811
VSS: 0
SPARK ADV: 21-23
IAT: 133
MAF: 0.746 - 0.762
TP: 0.0
AIR_STAT: OFF
02B1S1: 0.065 - 0.800
SHRTFTB1S1: -0.6 ~ -3.1
02B2S2: 0.095

I also got readings from the bank sensor's

MIN: 0.000
MAX: 0.248

(LEAN-RICH SWITCH)
MEAS: 0.024
MIN: 0.000
MAX: 0.152


02 BANK 2 SENSOR 1

(rich-lean threshd)
MOD: $10
MEAS: 0.365

(LOW FOR SWITCH)
MEAS: 0.300

(HIGH FOR SWITCH)
MEAS: 0.600

please anyone who knows the specifications for these codes shoot me in the right direction, thanks and god bless

 

Those arnt codes there readouts of what the sensors and ignition is doing for example you see the spark avd is at 0 when not running but 21-23 when running meaning the computer as advancing the spark 21-23 degrees before top dead center, as for the rest I really don't know how to read it that well.

 

dtc cnt is diagnostic trouble code count and yours is 0 so you dont have any codes.

 

thanks for the input

 

i had a vacuum leak, from a hose that connects to the intake manifold, which gave me 7 error codes

-p0171
-p0174
-p0122
-p0300
-p0410
-p0102

i changed the hose, reset the codes with the OBD2 scanner, and havent got any CEL lights since. thanks for the reply
