Manikulus Posted January 24, 2021 Report Share Posted January 24, 2021 Hello, Dear Forum Users, I have a Fiat Freemont, I live in Poland. I have my Freemont for two years and it was perfect up to now (225500km / 132000 miles ). My car cannot start, the engine is working but it cannot start. I've checked errors with MultiEcuScan and I got P0304, there I have changed the sensor. Now I have U0401 Error in communication with engine control unit (ECU) and still, a car cannot start. Does anyone have any clue where to search for problems? I have a contact spray for electronics and checking plugs and grounding but up to now no success. All fuses look fine, no visible circuit break. Thank you very much for any clue. Mariusz 2021-01-21_Freemont_Report2.pdf Quote Link to comment Share on other sites More sharing options...

Have you had proper service intervals followed such as Timing Belt replacement done? That code COULD be thrown from a belt that jumped a few teeth. You need to check the BASICS of proper engine timing. Also by Kms posted the Timing Belt should be replaced anyway., A worn Timing Belt can loose teeth and/or jump timing. Worst case is destroyed valves and pistons should the belt break. Manikulus and 2late4u 1 1 Quote Link to comment Share on other sites More sharing options...
Manikulus Posted January 25, 2021 Author Report Share Posted January 25, 2021 Thank you for the hint, it will be checked but in the workshop, I think it might be a bit complicated to do that outside where we have up to 5degC (39F). I hope nothing is damaged if this is a cause, I don't hear damaging noise... Quote Link to comment Share on other sites More sharing options...

A mechanic which was repairing was betting exactly about the same. Thank you for your hints. Till the next one... Warm greetings!

5rebel9 Posted February 4, 2021 Report Share Posted February 4, 2021 And greetings back to you! Thanks for posting back, but make sure you report what all it took to getting the {Journey}Fremont up and running again. I hope no internal damage was done.
