jimmyk Posted June 25, 2016 Report Share Posted June 25, 2016 2010 SXT FWD Journey. Code set is P2504 charge voltage high. Voltage checks out at 13.7-14. Car has other codes setting nearly every drive also. P0103 mas airflow circuit high imput, P0325 knock sensor #1 circuit, P0002 Fuel volume regulator control circuit range, P0203 injector #3. Dont know if these are all related or separate causes. Where to start? Quote Link to comment Share on other sites More sharing options...
jkeaton Posted June 25, 2016 Report Share Posted June 25, 2016 Clear the codes. Disconnect the battery for 20 mins or so to reset everything. See if it clears up. How does it run? dhh3 1 Quote Link to comment Share on other sites More sharing options...
jimmyk Posted June 25, 2016 Author Report Share Posted June 25, 2016 Sorry, I should have noted that I've cleared the codes multiple times with a scanner. All have returned. Runs well most of the time. I can feel when the #3 injector is acting up, slight shake on acceleration. P0103, mass airflow circuit input high voltage my be the cause of quick upshift to 5th and engine 'falling flat'. Doesnt stay in 4th but a second and shifting to 5th about 35 mph with light throttle Quote Link to comment Share on other sites More sharing options...
