Howdy everyone -

The check engine light came on in my dad's truck yesterday. He had the codes checked, and it is showing p0200, p0261, p0273. From what I can find looking through the 6.0 spreadsheet, the second two are injector 1 and 5 issues, but I can't find the meaning of the 200 code.

He said that there are no noticeable changes in the way the truck runs... no smoke, no rough idle, no hard start, etc. The light came on in the middle of a 20 mile ride yesterday, and he's driven the truck 30-40 miles since then (had to get home) without any issues.

What is the best way to tell if this codes are truly for injectors, or if it is an FICM issue?

FYI, he has a 2006 F250 with ~40k miles on it. The truck is bone stock, and he does not have any kind of scan tool or gauges (even though I've been trying to convince him to get some for two years). Of course the extended warranty ran out literally three weeks ago. He's going to take it to the dealer on Monday and see if they can do anything for him, but I'm trying to do some research for him in the meantime.

Let me know if you need any other info in order to help guide me. I have the same truck, but thankfully I have not had any issues yet.

Thanks for the help!

P0200 simply says injector circuit--0261 and 0273 are low circuit codes, which normally mean FICM. Do the FICM voltage test at home before you take it to the dealer. All you need is a DVOM, 8mm or 5/16" wrench, and a torx bit to fit the FICM inspection cover. The procedure is in the tech folder. If it's a failed FICM send it here: FICM Repair.com - Your Source for FICM Repair Ed Stefan can fix you up for a VERY reasonable price and great customer service.

 

Thanks for the tip. I've seen a couple of posts before on how to test it, but if there a good set of instructions somewhere? I'll have a hard time talking my dad into doing this over the phone, but if I can send him some directions, that would be great.

Also, I have a Insight CTS that measures FICM voltage... could I use that to troubleshoot (assuming I can get to his truck in the next week?

Is there any danger to drive the truck as is?

 

You can definitely use the CTS to do that. Here's a link to the test which is in the tech folder at the beginning of this forum: https://www.ford-trucks.com/forums/8...procedure.html There are repair procedures there also.

 

Perfect. Thanks for the link.

I wish I was local and could just hook my CTS up to his truck, but this will have to do for now.
