Dodge Repair Questions? Ask a Mechanic for Answers ASAP
Good morning and welcome to JustAnswer!!
Can I get the last 8 of your VIN also is the ABS or brake lights on?
Thanks for the VIN!!
There is a bulletin that addresses the C121C code and I attached it for you to follow.. If you have the old MAP style I would replace it first to see if it resolves your issues..
I hope this helps, and if you need anymore assistance all you have to do is reply..And feel free to request me for all your Chrysler-Dodge-Jeep needs.Have a great day,Brad
No if any of the codes are setting we start by replacing the old style MAP sensor first... I also attached the diagnostics for C121C as well..
Glad I could help and don't forget to RATE so I'm credited for my time
Have a great day,
Are you still here? Do you need more assistance?
Glad I could help and don't forget the RATING so I'm credited for my time..
