Code P0102 low voltage maf sensor
I have ground,12v, 5v. Across 3 Maf sensors,1 that is new. Cleaned TB front and back. New tps and iac. Have not found any vac leaks and tried 2 different intake set ups.
Idle is 650, surges/lowers when put in reverse.
Hesitation/bogs if I throttle to...
Tested both ways. 11v only when relay is disconnected. It fires up for a sec with starting fluid. Going to run and get a fuel pressure tester and tuner will stop by to verify vats delete soon.
Last issue keeping me from firing up.
[Red]Pin 9 fuel signal wire gives me 11v with key on constantly (when not attached to relay)(read its supposed to be 2 seconds)
When I attach the wire to the relay I get zero V.(tried 2 new relays)
2002 lq4 pcm.
Fuel pump runs when 12v applied...
