schalid Posted April 5 Report Share Posted April 5 Does anyone know a sure fire way of doing a relearn after replacing cam and crank sensors other than taking it to shop or DIY with a scanner?? The ways I have found it one other post they did not work on my 2010 Journey 3.5. I had cam and crank codes so replaced them, but still get codes back.

5rebel9 Posted April 5 Report Share Posted April 5 Without a scanner, the only way to erase and put computer into a relearn by driving mode is to disconnect the battery for a period of some time{folks offer varying amount} of 10 to 15 minutes. BUT, a 3.5 timing belt motor with an interference fit design...has the TIMING BELT ever been replaced? Your codes COULD be from a stretched or jumped tooth timing belt. Factory recommends 7yr 90k mile replacement, that most folks DON'T DO and pay the price later when the belt jumps time or BREAKS.

schalid Posted April 5 Author Report Share Posted April 5 I did the battery disconnect too and it didnt help. It runs and idles fine. But when you step on gas theres no snap to it. Quote Link to comment Share on other sites More sharing options...
5rebel9 Posted April 5 Report Share Posted April 5 (edited) You gave very little background info as to why you replaced those sensor. For that vintage they should be "plug and play", did you have CEL and just what P forat codes did you have? After your work, do you still have CEL and if so what are the codes? There is more involved to codes diagnosis beside just changing sensors. Edited April 5 by 5rebel9 2late4u 1 Quote Link to comment Share on other sites More sharing options...
