jimmyk Posted July 4, 2015 Report Share Posted July 4, 2015 2009 SXT 3.5L. Check engine light is on often. When scanned first time, codes were P0103, MAF voltage imput high, P0325 knock sensor, P0205 #5 injector & P2504 charge voltage high. That drive cycle I did feel a misfire, so that could explain the injector code. Cleared codes. Check engine light on again. Codes were P0103 MAF voltage imput high P0203 injector #3, P0002 fuel volume regulator control circuit & P2503 charge voltage low. Where do I start with this?

bramfrank Posted July 4, 2015 Report Share Posted July 4, 2015 Quite possibly a bad ground due to corrosion, or a chafed supply line or ground. . . . . . Quote Link to comment Share on other sites More sharing options...
jimmyk Posted July 5, 2015 Author Report Share Posted July 5, 2015 Thanks for that lead. Will look for bad or disconnected grounds. Prior owner had head gaskets replaced. Might have to pull plenum to check underneath it. Quote Link to comment Share on other sites More sharing options...
jimmyk Posted August 8, 2015 Author Report Share Posted August 8, 2015 I have not found any loose or corrosion to any ground wires underhood. Same codes keep resetting. Dont know where to start making repairs and dont want to just throw parts at it. Any suggestions? Quote Link to comment Share on other sites More sharing options...
adamcadieux311 Posted December 29, 2015 Report Share Posted December 29, 2015 Need help my 2010 journey 4 cylinder recently messed up big all dash lights came on and my car lost all acceleration. Managed to get it home for I was not far from it. Went to start it back up and wouldn't start changed my battery and started up right away but now I have a check engine light on traction control light on and my engine sputters with little to no power and my rpm needle jumps from 0 to 3000 without touch the gas pedal. Please help for I have little money and can do things myself what could possible be the issue? Was told it could be the tps (throttle positioning sensor) thanks for the help Quote Link to comment Share on other sites More sharing options...

jkeaton Posted December 29, 2015 Report Share Posted December 29, 2015 You need to get the code read and post the result. Most auto parts will read codes for free if you don't have a code reader. Quote Link to comment Share on other sites More sharing options...
