2004 F250 6.0 is stalling once it gets warm. I have changed ICP, Camshaft Sensor. IPR has been checked. Replaced standpipes and dummy plugs and nipples. Replaced fuel filters. Mechanic drove it for 30 minutes today and it did it again. He is at a loss. Can anyone help me?
Also now showing codes B1360 which ignition circuit and B1352

 

How did you check the IPR?

Sometimes an IPR will fail unpredictably when it gets hot, and sometimes doesn't throw a code when it happens. Unfortunately, a FICM (and a few other electronics) can behave this way as well. You can heat up an IPR (removed from the engine) and then test the resistance across the two terminals, and the issue will sometimes present itself.

Both B1360 and B1352 can be essentially "ghost codes". IMO, not to worry about at this point. What scan tool is being used to scan for codes? And yes, it can matter. MANY scan tools simply do not retrieve all of the 6.0L codes.

All that you replaced was fairly expensive. Did you have prior evidence of issues with the ICP sensor and low pressure in the high pressure oil system?

What bothers me when I see this is that sometimes a problem can be created by all that work. MANY, MANY people (even solid mechanics) have damaged new standpipes upon installation. A big reason for this is that certain quality issues in the replacement parts are being identified ...... even OEM standpipes (replacement parts) have recently been documented to periodically have quality issues. That said, aftermarket parts are even more of an issue - especially when it comes to electronics .... and even soft goods (quality of o-rings). Even Ford appears to be cutting costs in the quality of 6.0L replacement parts - it unfortunately is an old engine platform now.

Where did you get all of the recent parts installed? This information an be helpful.

 

So I just to got word he is bringing in a well known diagnostics guy who knows 6.0s like the back of his hand and will hopefully catch anything he missed or misdiagnosed. As far as parts go, I bought them from either pro source diesel or thoroughbred diesel. Not sure how he checked IPR, I just know he checked it when he did a rail pressure test. He used a real quality MAC tool scanner but idk what model. As far as the code 1360 goes I have seen threads of people talking about where it can stall the engine out intermittently because of an open circuit. I will come back on here Monday after a diagnosis and fill you in.

 

Please do keep us informed. I would not hold any high hopes that B1360 was pointing at the issue, but who knows I guess.

The proper resistance range across IPR terminals is 3-15 ohms. Typical values will be between 5 and 6 ohms. A heat gun can be used to heat up the IPR when removed from the engine for a simulation of a "running condition". This is the only way to test it for the possibility of a heat induced failure of the valve (and it is documented that this can happen).

 

Ok thanks for the feedback on IPR. I’ll be sure to bring it up Monday when the guy shows up to diagnose.

 

Good deal. Glad to help.

I have also found that a "known good" FICM is a good thing to have if a person works on very many 6.0L's!
