Ford 7.3L Power Stroke (1999-2003) :: 2002 F350 - Outside Temperature Gauge Reading Wrong
Aug 11, 2009
I have an 02 f350 7.3 power stroke...Yesterday I noticed the outside temp was reading wrong,it was jumping from 67 to 86 to 92 back to 67..Temp was prob around 90 with high humidity and my a/c was on..So I got to where I was going and when I restarted my truck to go home the fuel gauge dropped to empty(I just fueled the day before) and fuel light came on and outside temp still wrong on the overhead digital display...Are these two things related???
Stopped the truck restarted it and fuel reads correctly again....Went out today and fuel light back on and on empty...Outside temp wrong again,a/c is on .....I disconnected the batteries when I got home to "reset the system"if there is such thing, fuel gauge working but outside temp wrong..?? Where is the outside temp sensor ?could condensation be running onto the sensor and throwing off my temp gauge? Just strange that both these things happened at the same time......I don't think its a fuse or they wouldn't work at all. I should mention all the other gauges work correctly...

2000 7.3 EOT read 272* with engine cold new Ford sensor only getting 3.95 volts at sensor plug and at the 42 pin connector from PCM should be 5 volts, dropping 1 Volt some where I disconnected all the sensors that share this voltage IAT, EBV, ICP, IPR, MAP no change. I left the EOT unplugged and the truck runs good I'll run it like this.

I have stock 02 F350 7.3 with 74,000 miles ... Today i looked down and noticed my RPM gauge sitting there at 0 ... It was working just fine yesterday. I figured before i go digging around looking for the issue id see what is causing it not to read ..

Just bought this 1999 7.3 drove it a couple days now and got to walmart today. shut it off to go inside and came back out. turned on key waited for wait to start to go off. cranked the motor over but it didnt fire. i tried it again and nothing. oil is full, oil pressure is good while cranking. no rpm reading on gauge while cranking. no check engine light. batteries are literally brand new two weeks ago. Cam sensor?

I've had an ongoing issue with my fuel gauge reading incorrectly, and now I'm trying to fix it! Basically, it will change all over the place while I'm driving (not erratically, but definitely moves occasionally). I recently fixed my overhead display, but the "miles to empty" display doesn't seem to be very consistent. It will read 450 miles to empty, and then the next time I look at it, it will have dropped 100 miles or something (after minimal driving).
So I'm wondering where I need to begin looking to fix this problem. I've replaced the dash cluster using Circuit Board Medics, so I'm fairly confident that's not the issue. I've read that it can be the fuel pump or the fuel tank sender, but how to check if these are actually the problem or how much time it will take. Luckily, I've never run out of fuel and been stranded, but I need to fix this or it's only a matter of time!

Basically my coolant temperature gauge either reads as the hottest it can be, or the coldest. It doesn't jump around a whole bunch, but it's always all the way to one end or the other. From what I've read there seems to be a lot of different temperature sensors, so I get a little confused with all of the abbreviations, but I'm fairly certain I checked the correct one, next to the thermostat housing.
Using a multimeter I checked the resistance of the sensor, and it was around 600 ohms about 30 minutes after it had been driven. I'm not sure if this is where it should be or not, but it was rising as the truck cooled off.
Anyway, I'm not sure if I just tested the sensor incorrectly or if there could be another issue. A friend of mine suggested that the thermostat may have gotten stuck or something, but it doesn't seem like the gauge would switch at all if that were the case. What I should check to try and fix this.

I have a 2005 v6 ford mustang and lately the rpm and the gas gauge have been misreading. At first the it was the gas gauge that was reading off then the rpm gauge soon after. However, sometimes the rpm gauge will be working right but my gas gauge is just completely wrong. The other two gauges are working just fine( temperature & speedometer) ...

I have a 2002 f350 that has had cold starting issues since I bought it. I have replaced the glow plugs twice, the glow plug solenoid four times. When I put a new solenoid on it it works fine for a short time. I know the solenoids are bad because I get battery voltage on one side and nothing on the other. If I jump the solenoid with a jumper wire I can get the truck to start. I thought I was getting bad solenoids but I have recently tested the activation circuit and am getting constant power there. I.e. It never shuts off. I think this is what is causing the solenoids to burn up. From the tracing of wiring diagrams I have done, the only thing before the solenoid is the Pcm. So now to the question,
1) What controls the activation of the Glow plugs? Is there a temperature sensor or something before the Pcm.
2) Is this a case of my Pcm going out on me? I am a mechanic in the army so I have a decent understanding of mechanics.
However I am at a loss for these systems.

My issue I'm having - 2002 F350 7.3L has an 8 inch bds lift with 37/13.50 tires. I realize these tires are big but... while driving 100kms/hr or 60 miles per hour and I hit the gas the truck barely wants to move (without pulling a load). Thought maybe a turbo but I have no mechanical skills so here I am!
2nd issue, there's a bullydog chip in that truck when I bought it. he said he always ran it on extreme. I found it puffs way to much black when on extreme and on performance it seems a lot better so that's where I have it?.
3rd issue, the transmission gauge on the dash goes into red when climbing up hills ( I live in the rocky mountains so a lot!) but the bullydog chip says the tranny is only at its hottest 140C? I don't believe that's to hot but I do believe my truck is derating a little while the tranny gauge on the dash is in the red? is there any quick fixes out there for these issues.

I have a 2002 F350 4wd with the 7.3. I was driving the truck and all of a sudden it was running like crap. the engine light was on. after a minute or so the engine light goes off and the truck is running fine. then again starts running like crap. I am close to the house so I limp it home. runs like crap.... will barley climb small hills. engine light is on. get home turn it off... next day... starts up and runs great for 10 - 15 min. engine light comes back on... runs like crap.... my neighbor says "It's the crank position sensor" I replace it.... runs great for a month.... now it's doing the same thing......

I have a 2002 f350 dually with a 7.3 and 197k. At 186k it died while driving and I had it towed home. As soon as the tow truck dropped it the truck fired right up like nothing was wrong. Then it died again 2 days later. I replaced the cps, but the fix was replacing the icp and pigtail. Now it is doing the same thing again. It died on my wife while driving yesterday, i had it towed to the dealership I work at and it started and ran for about 2 hours with no issues.
I hooked up the factory IDS and had a diesel tech look at it with me. The oil pressure, injector circuit and injectors, and IPR all look good. The batteries were a little weak so i replaced both of them. I drove it home yesterday, about 10 miles, and drove it around town today. Then i tried to jump start my 96 bronco and after about 10 minutes of running it sort of hick uped then 5 minutes later it died and would not start. I let it set for 30 minutes and it started and died after about a minute.

2002 F350 7.3 intermittently wont start after I've shut it off, it runs fine but sometimes won't start when it's (warm)? Wait hour or more and it starts right up.
Is there something I can look for before I bring it to a mechanic?
Just to clarify I am a gal with little wrenching skills but I can look at videos and follow directions if it's not too involved.

2002 F 350 7.3 4x4
Aftermarket gauge will climb to 250 after around town driving of an hour or so or multiple trips within the hour. Not towing. 160,000 miles on odometer. Changed trans fluid at 40,000 mile intervals. Most recently about 1500 miles ago. Most recent change using Mark K's method. Was getting fluid from rear port when I changed fluid. Blew out oil cooler and there did not seem to be a blockage as flow was sufficient.
Still overheating according to autometer trans gauge in test port. No codes retrieved using auto-ingenuity also O/ D light is not flashing. Would like to run torque converter slip test using AE according to wooden things method but TC slip desired and transmission gear ratio is not available under that name in live data meter. AE just updated to most recent version.
I purchased a new tranny oil bypass and will install soon. Also purchased a new 6.0 cooler to replace stocker but am hesitant to install if tranny is failing because I am concerned that the new cooler will just get some blockage from a potentially failing transmission and I will be buying a new cooler along with a BTS rebuild.

I'm trying to figure out what axle I have on a 2002 f350 single wheel 4x4 so I can order a replacement seal. So this morning I got to work and noticed that am oily guild was dripping from the front of my rear differential where the drive shaft hooks into it. I figure it the seal, so when I went to look up the repair kit they list several different axle options because of gearing, what axle I have as there wasn't a in owners manual with the truck. Who can I find out what axle I have so I can buy the repair kit for it...

I finally got my 02 F350 running again after replacing the Fried PCM, but during some additional shop prep work, I discovered that the engine dies when you use the horn button, it will start right up afterwards so no permanent damage, but, Where to start? I have Forscan and a cable so I can get into the PCM but I need to know where to look or what PIDS I should be watching during troubleshooting.

I have an 02 F350 7.3 ... I just installed my glowshift tripple gauge pillar set. I have an EGT, Boost and fuel pressure gauge ... I followed all the constructions on installing them. The boost is working just fine and the EGT was too, but after a while the needle started going back and forth and the red warning light what blinking and then it just sat at 0 with the warning light on and stay that way. My fuel pressure gauge is connected to a sensore i put in my fuel filter housing, my fuel pressure gayge right from the start stayed at 30 psi with the red warning light on and just stays there .... Also the buttons to change the color and set the peak on the EGT gauge are sticking for some reason and staying down and aren't letting me change the color ...

I have a 2002 f350 7.3. It was running fine 2 days ago. After I put some diesel in it my water in fuel light came on. I drained the water out and took all the fuel out and put fresh diesel in it. It starts up fine and idles okay but when I try to drive it it looses all power and acts like it's starving for fuel and almost dies. It was smoking white smoke for a little bit even after I took all the water out but now it's black. What it could be.

I'm new to diesels and I've got a 2002 F-350 w/7.3L 224K miles. I've had it for about a year and had no problems. Burned a little oil, about a quart every 1000 miles or so, but in the last two weeks it's gone through the roof. I have gone through roughly 12 quarts in 300 miles. I see a lot of blue smoke at start up, and it's being harder and harder to start in the cold. From what I've read it could be several different things, and I plan on doing the CCV delete and changing the orings on the injectors just for good measure. Is there anything else that I might check as well, or am I completely off base on what it might be?

I just changed u-joints and the carrier bearing on the rear driveshaft. I now have a "howl" somewhere back there. The noise starts around 30mph and goes away around 40mph. There no vibration associated with it. The sound goes away after driving for 15-20 minutes.
I double check all my marks on the driveshaft to make sure I put it in the way it came out. I put it up on jack stands and ran it up to speed but couldn't replicate the sound that way.
The truck is a 2002 F350 7.3ltr DRW.....
