Ford Super Duty (1999-2016) :: Engine Temp Gauge Pegged Out And CEL Came On - P1299 Code
Jun 7, 2015
My truck threw a code p1299 last night on my way home from the lake. I was towing on a huge grade and all the sudden my engine temp gauge pegged out on me and check engine light came on. I pulled over and noticed a bunch of coolant had overflown the cap but the engine didn't seem to have over heated. When I restarted the truck the engine temp was immediately normal range. I drove for another 30 min or so and the engine temp started to climb and then come back to normal then climb and stay pegged. I pulled over again and noticed the coolant level was low and coolant had overflown the reservoir. I restarted the truck and once again it was normal. I just drove surface streets the rest of the way with no issue. I suspect blown head gasket. This is a 2003 F-250 6.8L with 100000 miles.

(The truck is a 05 f250 with a 5.4l). The problem first started out with the engine temperature gauge spiking and then resetting itself when the truck is turned off and then turned back on. If I drove the truck for any distance it would go into limp mode and the CEL would come on. The code was p1299, which is the cylinder head temperature sensor, and I replaced the sensor but no luck. Then the shop and I went through all accessories hooked up and couldn't find a short until I remembered that my prodigy break controller would occasionally read "ol" or "sh" which both readings are from shorts. I tow a enclosed trailer about 85% of the time and the past week I have been towing it with a different 250 and the same break controller without a problem so I have eliminated the trailer. But the shop just said the problem was the controller and unhooked it.
Now the next day it threw the same code with the controller unhooked and the trailer hooked up. after thinking it seemed that it was happening when i accelerated so I took apart the 7 pin and sure enough there was a little water in it, but after driving it around for a little and no code being thrown I hooked my break controller up and it still was showing ol or sh so i believe there is still a short. Also I noticed that my voltage is reading right at 13v instead of the 13.8-14v it was reading before this issue arose. I think I have narrowed it down to the 7 pin harness and/or electrical in the break components, but do not know what would loop back to the temperature sensor.

1999 F350 SD ... Yesterday when goosin it to get on the highway my rig threw up a code quickly and engine temp started to increase. Once temp got in the red, oil pressure got a little figgity. The code was for the ICP(p1212), so I cleaned the plug and made sure coolant and oil were topped. This morning she ran barely over normal temp (stock gauge). This afternoon same thing as yesterday but without the code. When I let off of the accelerator temp goes down. I just got married so I have little funds to throw at a shop.

I have an 02 F250 V10. Ive always wondered about the transmission gauge. It seems to always point to the middle of the gauge range. This weekend I was pulling my car hauler up and over the Ozark mountains, and when I stopped for fuel I noticed the transmission was vomiting fluid underneath the truck (and on my exhaust creating a nice smoke bomb for everyone around me). The gauge indicated normal temps. It kind of gave me a sick feeling. I have ordered the 6.0 Trans cooler from Rock Auto and a new temperature sending unit. Do the trans temp gauge is supposed to move or is it pretty much useless?

I had a mechanic replace the temp sensor on the top of the intake in my 2001 f350 v10 and since then my temp gauge doesn't work. He replaced the sensor again and still nothing. Is there a different sensor/sender that controls the temp gauge???

I got in my 06 f250 tonight and my digital read out on my temp control not working. My heater and A/C works but when I turn it off my outside temp is not on. Whats going on?

Have a 2003 5.4 F-250 ext cab 4x4. The speedo went crazy of a couple days, now it is pegged when off at 100mph. When I drive down the road it goes down to like 70mph. I replace the speed sensor on the rear axle with no success. Also the airbag light came home on the way to work today. Not sure if that's connected or not.

I have had this issue with the truck 2008 F-250 6.4L since I bought it a year ago. At first it seemed as if the truck wouldn't start whenever the water temp gauge was working while she was hot. When the gauge wasn't working she would start right up like a champ. Well a year later ( have only been driving it for 6 months) a full engine rebuild, new high pressure fuel pump ( injector pump on top the engine below the turbos) she still won't start when she is hot. What the issues are.
Right after the engine rebuild I was getting the p088 code which is for the hpfp but since I cleared the codes right after the engine was rebuilt I haven't gotten the code again. I replaced the high pressure fuel pump this last weekend hoping that it would solve all of my issues and she would be like brand new again, but it didn't do anything. When I ran codes right after I installed the high pressure fuel pump I got a few codes p0684 which is the glow plug control module p0284 ( google said) gear lever y position correct but I'm unsure if that's right.
P0528 which is the fan speed sensor circuit ( that was unplugged during the removal of the hpfp and power steering pump or the radiator) p0480 cooking fan circuit ( also unplugged ) p174e out put shaft wheel speed correlation ( not concerned about that one) p008c fuel pump control circuit p008d fuel cooler system ( taken out and unplugged using installation of new hpfp) p115a ( low fuel level forced limit power) that is from trying to start while she had a little bit of air in the system after replacement) p2291 injector control pressure to low- excessive cranking ( probably from the air in the fuel system again). I cleared all those codes once I got her up and running again. Checked for codes yesterday and the only one that came up again was the p0684. Where to check next for this hot start issues,and don't know what to do at this point.

I have been having a problem with my 2002 F250 Super Duty 4x4. It started about 2 months ago. I was in traffic (truck hadn't even been on for 15 minutes). The temp gauge spiked, so I pulled over and turned the truck off. I turned the ignition on and the gauge was normal so I started it and all was fine.
Fast forward a little and every so often about every 3 weeks it would overflow (coolant) but not get to the point that it would overheat. I changed the thermostat and all seemed good to go. Fast forward to yesterday morning. Got in the truck and left to go hunting, and I didn't even make it 10 minutes down the road when I turned the heat on and it blew cold.
I started to see the gauge creep up so I pulled over and shut it down. Upper hose was cold, lower is cold and both heater hoses are cold. After some time of waiting, I started it but the gauge kept creeping up and no heat, so I kept shutting it down. After about 5x of this, the heat worked and the upper hose got hot and all was right with the world. SO I drove it home. Coolant is new, flushed about a month ago and was running great since then. Thermostat is new. Do I have a blockage somewhere? Water pump bad?

When I purchased my truck 1999 F350 about 5 years ago, I was told it was on its third transmission since the awesome 7.3 diesel engine has 200,000 miles on it. At first I noticed that going up a hill with the truck empty would cause the tranny temp gauge to climb to 250 degrees F. Nowadays when I tow my boat or carry my camper, the temp gauge pegs over 250 and the overdrive light flashes steadily when I do any hill climbs. I have had the fluid flushed several times, and I have a large fan powered oil cooler too. I also recently noticed that the tranny heated up when the truck is just idling in place.
I just got back from burning man and during the 800 mile round trip the overdrive light started flashing at least 6 times and the temp gauge read over 210 the whole time, with it pegging over 250 during hill climbs. No fluid boiled out but I am very concerned that damage is being done.
Is it possible there is a clog in a line somehwere restricting the flow of oil? Or should I replace the tranny?

Ok so here here goes I have a 1999 f250 super duty with 5.4 triton it seems to be over heating but the gage stays in the normal operating temperature range. I just changed the water pump. Could it be the thermostat and Would it hurt to remove the thermostat until I can get one...

I replaced the sensor on top of the water pump and the gauge still doesn't work. I tested the gauge by unplugging and grounding out the wire and the gauge goes all the way up. What I can try next. I didn't get a Motorcraft sensor so I'm going to go get one of those tomorrow hoping the duralast wasn't correct even though it looked 98 percent identical to the original. 7.3 lite diesel.

2003 f250 5.4 86000 miles. When I start the truck, "especially after it sits a day or more" it starts to fast "Rushes". Like the gas pedal is all the way to the floor. I have taken it to the Ford dealer and they say they can find nothing wrong. They say all fords start up fast but I know this cannot be right. If I start it and let it run awhile then start it again it starts much slower. It only rushes like that a second or two and slows down. Today I noticed that when it started all the gauges pegged out. The speed indicator went up past 100mph sitting still in park. Then they all dropped down to zero then back to where they should be.

My F250 with V10 has developed an overheating problem. While driving, the temp gauge suddenly shoots to max, and the truck goes into limp mode. Turning off the truck and ignition, waiting a few minutes, and all seems to be well again - sometimes for only a minute, sometimes for several days. No steam leaking, the water in the reservoir seems to be normal temperature, the radiator is not overly hot, and the AC keeps on blowing ice cold. Me thinks it is not really overheating, it just thinks it is. So where to start? Change the temp sensor first, or the thermostat? It seems the hoses are fairly firm, I don't believe they are collapsing from suction.

The truck I'm working on is a 2003 f550 with a 6.0, and 382000 kilometers. My service truck died on me couple days ago, while running. As I rolled to a stop, I noticed that my temp gauge on the dash dropped to cold. (Truck was hot). Tried starting, and I have a crank, no start situation.
After towing it to my shop at work, I hooked it up to my scanner, and found that the pcm will not communicate with the scanner (otc genisis). I have no injector buzz with key on, wait to start light comes on for an abnormally long time. I have 48.3 volts on the ficm,(4 screw), and haven't been able to find any chafed wires as of yet.

So a couple weeks back I'm on expressway home and I look down and and temp gauge is pegged out overheating I immediately pulled off and shut it down and towed to a buddy of mine's shop he flushed it filled it up w antifreeze and checked for leaks and couldn't find one. I drove it for about a week and got out to for a quick stop , Ex parked on a slight decline and came out to prolly half gallon of coolant on the ground..I limped it to my buddies shop as it was not running hot .. he has checked it out but can't find any leaks, even after having it run 30 or so minutes..

I keep getting this v0100 code in my tuner. Says lost communication with pcm/ecm? Bit truck doesnt die. Still runs but the rpms goes way higher before turbo kicks in?? What keeps causing this? Also my cluster gauge keeps shutting off and on so the cluster is going out. I will be replacing it. Do these two problems go hand in hand?

2001 f250 5.4L v8. Engine temp seems really low. The gauge is reading barely above the cold in normal range. The heater is only blowing out 75 degree air at the warmest. It gets to its normal temperature with in 15 minutes even when its real cold out. I live in Minnesota and its been a really cold winter so having hot heat would be nice. I just bought this truck at the beginning of the winter. Whats going on?

Driving my 2003 today seen the "check gages" light on and the trans temp gage pegged on hot. CRAP, tranny time! look at the edge evo and it reads trans temp as -60F ???. Plugged in the torque pro and it reads 8,240F. At that point I figure its PROBABLY not that hot. Let it sit for a while and back to normal. Watch trans temp on torque pro as I drive it and everything is fine till it gets to about 150, then it jumps to 60F, then 30F, the 8240F. The cooler lines and trans pan are both feel normal. Picked up a new temp sender on my way home.

I have a 2000 Accent GL with the 1.3
I was driving home with a known overheating problem, when the temp gauge pegged and a heard a distinct rattling. I knew right away what happened. as I pulled over the engine stopped turning. I opened up the hood, and my suspicions were confirmed. I blew a headgasket. I went back into the car to call AAA, and I heard a loud POP!! the radiator blew from the heat and pressure.
after it got home and cooled down I tried cranking it over and it has NO comression. it just spins.
should I take the time and money to replace the headgasket, or should I just get a junkyard motor?
I know I need a new MAF. I had a "multiplicative fuel system running lean" code for a LONG time. I regrettably assume this is what caused the failure in the first place.

I have had the truck sitting for almost 2 weeks now and live in the Midwest. It is about 35F outside today and finally got to drive it. When I started the truck and let it warm up for about 3 minutes I backed out and started driving. in total the engine ran 6- 8 minutes and the transmission temp moved off cold but the engine was still reading cold. Is this normal in this truck? Mine is a 5.4 gasser with the 3.73 rear.
