I have a 2004 chrysler pacifica with a 24 valve 3.5 liter. It developed a misfire and is throwing the following DTC's:

P0202-injector circuit open / cylinder 2
P0201-injector circuit open / cylinder 1
P0461-fuel level sensor A circuit range/performance
P2066-fuel level sensor B performance
P0700-Transmission control system (mil request)
P0562-system voltage low

The dealership said the problem is the PCM (powertrain control module) and it needs to be replaced but I'm not sure this is the problem.
I dont see the PCM causing an engine misfire, especially with no transmission problems. I'd hate to spend hundreds of dollars to accomplish nothing.

Any insight is appreciated.

Thank you.

Why don't you think that is the problem? Have you done testing to dispute their claim?

P0202 and P0201 that set current will cause misfiring in those cylinders. Yes, a faulty PCM can cause misfires. If there is a problem with the injector drivers, which are inside the PCM, that will cause misfires. There are diagnostic steps and procedures to determine what is going on.

If you don't agree with their diagnosis, you could have it checked out at another shop.

Since we volunteer our time and knowledge, we ask for you to please follow up when a problem is resolved.

Yeah, I've got the same problem. Damn doctor says my leg is broken but I don't think that can make my toes point backwards and i don't want to waste the money on a cast. Maybe I just need to take some vitamins.

TALK with your service provider, find out what their policy is if this repair does not does not correct issue-
nothing wrong with asking how they arrived at conclusion- you already paid for diagnostics...
