P 0105 code wont clear
I recently failed emissions because of the following:
p0325: knock sensor 1 circuit malfunction ( bank 1 or single sensor )
p0105: manifold absolute pressure/barometric pressure curcuit malfunction
went to my mechanic and after much back and forth with parts ended up replacing the following parts:
1. knock sensor
2. starter
3. electric harness behind ignition
4. boost sensor part # 2508554u01
5. vacuum solenoid part # 1495635u10
6. vacuum solenoid part # 1495638u01
7. vacuum solenoid part # 1495631u01
My mechanic checked all wiring and hoses, cleared the codes, and i drove off ....the starter and ignition were unrelated to the codes but a problem i had been ignoring.....anyway the check engine light returned, and when he checked the codes the knock sensor code was gone but the p0105 was back....he doesnt know what else to do and i sure dont....ive read all the info i could find on here and talked to a nissan tech that recommended the boost sensor, so i was wondering if anyone else had a problem clearing this code....thanks

This is what I pulled from assit as I work at Nissan Consumer Affairs.
CONDITION: The MIL light is on. DTC P0105 (absolute pressure sensor) is stored in ECM memory. No voltage is available to pin 3 at the absolute pressure sensor harness connector F45 ("R" wire).
SOLUTION: The "R" wire may be damaged or broken approximately 8 inches from connector F45. If so, repair the wire and insulate as necessary to resolve the incident.
This might be your problem but this was something that a tech found and it was put in the system as a tip.
Is the vehicle giving you any driveabilty issues?

Vehicle drives perfect....just wont drop the code......had nissan look at it....they say i need to replace the entire wiring harness because previous owner did some splicing to it thats causing the ecu to not read all the sensors correctly.....damage to the tune of $2300.00! : C
