Customer Question
Code P0304 CNF MOD...

Code P0304 CNF MOD 10, what does the CNF MOD 10 mean?

Mechanic's Assistant: Just to clarify, what's the exact code? And have you tried to reset it?

P0304 CNF MOD 10

Mechanic's Assistant: What is the model of your '10 Ford?

2000 f-150 5.4 liter

Mechanic's Assistant: Are you fixing your F150 yourself? What have you tried so far?

Changed the plug and put in a new coil pack. No water leaks from the heater line, have tried to reset it several times, it goes out and comes on 3-4 days later.

Mechanic's Assistant: Anything else you want the mechanic to know before I connect you?

Just curious about what the CNF Mod 10 means

The p0304 has a definition of cylinder 4 misfire. CNF MOD 10 does not relate to the code but may be something to do with the scan tool that retrieved the code.

What Customers are Saying:

AlvinC answered a question about my Ford truck that only someone with an in-depth knowledge of his subject would have known what was going on.

Rich DUSA

Because of your expertise, you armed me with enough ammunition to win the battle with the dealer. They are installing a fuel filter and fuel pump at no charge to me.

MollyUSA

I needed help with my car on Saturday morning....got a response in 5 minutes, and it was the perfect solution. Thanks again to your service.

Jason V.Kirkland, WA

I do know, after going though this with JustAnswer, that I can somewhat trust my mechanic but I will always contact you prior to going there.

BRNew Jersey

I would (and have) recommend your site to others I was quite satisfied with the quality of the information received, the professional with whom I interacted, and the quick response time. Thanks, and be sure that I'll be back whenever I need a question answered in a hurry.
