Hi I have a 2008 f350 Crew Cab, 45k miles with the 6.4 and automatic that is throwing a P1335 ODB code and now the truck won't start.
I saw in another thread that the P1335 code stands for:
P1335: EGR position sensor minimum/maximum stop performance - This code means that the EGR valve position voltage is greater than the allowable limit when closed and is not being commanded by the PCM. I have two different specifications for this: 1.3V>2.5 seconds and 1.5V>2.5 seconds but the indication is still the same. The possibilities include a stuck EGR valve, debris preventing the valve from fully closing, wiring concerns affecting the signal voltage or control circuits and the PCM. What do these codes mean? P0404 & P1335
but this person didn't mention having issues with there truck starting.
Anyone else have the same code thrown and NOT had there truck start? I live in Anchorage so I guess its a possibility that the EGR is gummed up from idling on -20 cold days.
Mine did exactly what's above. It sounds like an EGR valve. Mine took two weeks to get back. The dealership had a lot of trucks ahead of me. Hopefully yours will be faster.
Oh man that blows.
I have a block 1 truck and I think I read somewhere that the newer trucks have a revised EGR system. Will the dealership be required to replace mine with a newer version?
Also if you take your truck in for warranty work will they automatically replace any other parts that have been recalled? I also had the problem of mysteriously disappearing coolant. Im hoping that gets fixed too.
My truck’s EGR valve was changed back in January, and there were 3 other trucks at the dealership at the same time waiting for the EGR valves. The first one that came in had to be towed in 180 miles. Mine went into limp home mode, the cruise control didn’t work, no warning lights and was throwing code (P0401?). It happen the day before New Year’s Day, it went out of “Limp Home Mode” so I drove it to the dealership on Monday so they could tell me that they cleared the code and had to order the parts.
As I understand, the first truck that came in got the dealership’s last in stock older version #1 EGR valve (I wonder if he knows?); the rest had to wait till more came in. I was told that they were on order and that I shouldn’t take my truck out of town, so I wouldn’t get stranded on the highway!! It turn out that they were on back order and I had to wait 2 weeks.
I really can’t get any answers from my dealer and calling Ford Direct is even more frustrating. So here is my thought, from this forum I was told from a member that in deed they had a back order at the time, on the EGR valves and were waiting on EGR valves from the supplier. That the EGR valve can be seized in the housing and make it a ***** of a job to replace and some dealership will change both.
My Dealership changed my EGR valve with a version “2” and also changed the housing, probably because they don’t have the special tool to pull the EGR valve? Since they wouldn’t or couldn’t tell me why the new version change, I can only imagine the worst, of course I’m way past using the little people skills I have left, talking to Ford. I for one want to know why my truck has different parts then the next truck, and if it is a better part, I want it now, not when my warranty is up and I have to pay for it. Aren’t the cooling systems on these engines important!! (Of course it is!).

Thanks for the info. I just got a call from the dealer saying they were in the process of replacing my EGR valve and it should be done today. Luckily I didn't have to wait on a parts order. I asked if they were replacing it with an updated version and they didn't know. Hopefully I can find a mechanic and get more detailed info.
Picked my truck up from the dealership. I got a chance to talk to the mechanic. Actually he came to talk to me. He said several other trucks were in the shop all having their EGR's replaced. He was really knowledgable and actually took a lot of time to answer some of my questions regarding the EGR. He said they used the version 2 on my truck. Also he said my EGR was completely cooked and that it broke into about 30 pieces when he finally knocked it loose.
He explained to me that in Alaska the average cetane levels for diesel is about 36 and that Ford recommends diesel with a cetane level of 46 so I should run a bottle of cetane booster everytime I fill up. He said he added a bottle to my tank and added some fuel after the EGR install. The dealership actually had a posted bulletin regarding Alaska diesel fuel. I can scan it in if anyone actually wants to see it.
On my 35 mile trip home I averaged 13.5 mpg compared to my normal 10.5. Could be due to the EGR or the Cetane boost or a combo of both. The truck definitely felt more responsive. Either way I am definitely pleased.
Glad to hear it was only the EGR valve and not something worse. Mine felt more responsive also when I picked it up. I always use cetane boost because the levels in Maryland are around 38-39. It does help with the mpg's and I think it helps with fewer regens (400-500 miles between)
