p1682
p0500
p1694
p0602

i looked all of them up, they dont seem like major codes. but id still like yalls opinions.

truck runs good, just a lil funny on the top end. kinda hard to explain. almost like a miss. only mods are m4's and smarty.

no check engine light or anything.

any info is appreciated.

 

That is quite a range of codes.....from speed sensor failed to ecm programming errors.....I think I'd clear them all and see if any come back.

 

ok thanks. im gonna try that.

 

The 0602 is standard with the Smarty. I don't see a fuel pump mod in your sig. If your running a stock lift pump you may be running out of fuel on top causing the miss.

 

i have a holley blue with 1/2" lines all the way to the vp.

thanks

 

P0500 (M) No Vehicle Speed Sensor Signal No vehicle speed sensor signal detected during road load
conditions.

P0500 (M) No Vehicle Speed Sensor Signal A vehicle speed signal was not detected.

P0602 (M) ECM Fueling Calibration Error ECM Internal fault condition detected.

P1682 (G) Charging System Voltage Too Low Battery voltage sense input below target charging voltage
during engine operation and no significant change in
voltage detected during active test of generator output
circuit.

P1682 Charging System Voltage Too Low Charging system output voltage low.

P1694 Fault In Companion Module No CCD/J1850 messages received from the powertrain
control module-Aisin transmission

P1694 (M) No CCD Messages received from ECM Bus communication failure to PCM.

0500-No vehicle speed sensor signal
0602-ECM fueling calibration error, standard when you use a Smarty.
1682-charging voltage to low
1694- no bus messages from ECM module.

 

Maybe have alternator checked out. Check and clean all grounds on truck.

 

ok i cleared them, ran the truck. truck ran awesome, i couldnt tell anything was wrong.

so i get home cycle the key 2 times and all 5 codes came back.

so i hook the smarty up and it only pulls 2, 0602 and 1693.

what gives, why is the smarty pulling 2 and the truck showing 5?

thanks for all the responses.

 

dont you think its odd to have all those codes and the truck run fine?

 

i've never tried cycling the key only twice, maybe that brings up fault history instead of current faults. think i'll try it.

 

anyone think it could be my crankshaft position sensor?


also truck is missing a lot more while driving.

 

well im lost, not sure where to look. i really thought it was my crankshaft position sensor, but i dont have one.

any suggestions. truck runs good most of the time, just misses or sputters in the higher rpms.
