Need help w/ Codes!!!
Trans has been redone as well, but still shifts hard. Got some electrical problems... These are the codes that i pull up...
P1670 - Electric feedback sig not detected
P0720 - Speed sen output ckt malf
P107 Map bar pres. low imput
note that I don't have my abs in the front. never re-did it.. my budy is thinking that has something to do with it. I hope someone can help. I'd love to drive this damn truck, but its just a headache!!!
Also.. I have a problem with getting any boost out of my turbo. we checked to make sure the turbine wasn't messed up.. so I'm not sure what to think about that.
Hope someone can help!!!
thanks
KOEO diagnostic trouble code P0107 indicates barometric pressure out of range low was detected during KOEO Self Test.
Continuous diagnostic trouble code P0107 indicated barometric pressure out of range low was detected during normal operation.
Possible cause:
-- faulty internal BARO sensor (PCM)
Re-run KOEO On-Demand Self Test.
Is P0107 present?
Yes
REPLACE PCM. CLEAR DTC and RETEST.
No
BARO fault (PCM) is intermittent. If code reappears, REPLACE PCM.
DTC P1668 and P1670 indicates that a communication error has occurred between the PCM and the IDM.
Possible causes:
-- Open fuse
-- IDM relay
-- Open or shorted IDM enable circuit
-- Open/short in EF circuit
-- Open/short in FDCS circuit
-- IDM powering circuits
-- PCM
P0720 - Insufficient input from Output Shaft Speed sensor
The output shaft speed sensor inputs a signal to the PCM, based on the speed of the output shaft of the transmission. The PCM compares this signal with the signal of the VSS or TCSS and determines correct tire size and axle gear ratio.
Possible Causes:
-OSS sensor circuit short to GND
-OSS sensor circuit short to PWR
-OSS sensor circuit open
-Damaged OSS sensor
-Damaged PCM
Hope this helps.
Thanks for the info too. Its always nice to see that soemone on this forum is always willing to help!
