Where can a transmission temperature sensor be mounted on a 1999 manual powerstroke transmission? What is the part number for an applicable sensor that will work?
View 2 RepliesI 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.
How does one get to the top mounting bolts to engine? Are special tools required? Is there an access plate?
View 6 RepliesAs my truck stands it has OEM automatic locking hubs with a selector for auto or lock. So, why would some one buy manual locking hubs and cap off the ESOF vacuum line when the OEM ones perform the same function by being auto or locked?
I hope this makes sense because if I felt I wanted to go to manual style locking hubs, I think I could simply cap off the vacuum line and then switch the hub to lock if I wanted 4x4 because the electric switch inside the truck is actually what engages the transfer case and puts the truck into 4x4.
Is this thinking/theory correct or am I missing something here?
Ok, I am looking to update to the square style mirrors with turn signals (nothing else) is this possible and is the wiring for my E99 already in place or would I need to add any thing else? Here is a link to the mirror set I am looking at :
99 15 Ford F250 Rear View Tow Towing Mirror Manual with Functional Signal Pair
Is what I am wanting to do possible, I know I could wire in the auto folding style with the stupid add a fuse crap and a button (easy enough)... or these...(power fold). [URL] ....
I know this is going to sounds lame, my wife can't turn them, they have cover over it that has to be unscrewed to get at 'em. It would be nice to shift in and out "on the fly" as weather condition change.
Is it a difficult change?
My truck has a bit of an interesting trait. Unless it's just about freezing, my transmission is just about always at operating temperature. If it's 50*F outside and I start the truck, the Trans temp is smack dab in the middle. If it's 30*F outside it starts just a little above cold then is "warmed up" when I drive it down my short street block, which ain't right.
All the rest of the time, it's always reading middle of the bar temperature. My old 5.4L never did this. My 7.3L does. Best I can tell is it's a fault in the temperature sensor for the transmission. I don't have a scan gauge yet to get the readings but will be getting one. Just need to know where the sensor is at so I can have a starting point.
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 am intrigued by this engine and it's cold start issues so I am trying things out to see what works. If I plug it in it starts like summertime. If it's as cold as 30* out I run the glow plugs for two minutes and it starts without much effort and once running purrs like a kitten, no chug a lug, no romping, little smoke. When it gets down into the 20's I run the glow plugs for two two minute cycles, a little more cranking time but starts same as above. Down to 18* and I cycle the glow plugs twice for two minutes and it cranks, tries to start but won't. Key off, back on for two more minutes and it starts right up like a warm summer day. It hasn't been colder than 18* here this year so this is the end of my report for now. I haven't taken the time to check the glow plugs which is on my list but this summer it'll get done.
View 14 RepliesI have a 2000 F250, 300k. Starts beautifully when cold, takes 10 seconds of cranking when at Operating Temperature. Did the injectors and plugs in September, kept doing it and now that it's summer it's getting harder and harder to start. Just replaced the ipr, still doing it. Gonna do an overdue oil change tonight or tomorrow, I'm hopeing that will improve it. I can understand 3 or 4 sec of cranking, but not 10. Truck hads no drivability issues whatsoever. Will an ICP fix it? Change to a heavy-duty 20w-50? (Last oil change was delo 15w-40) The code reader that I have is really basic, and only shows me RPM and map.
View 14 Replies5 months ago I brought a f250 7.3 2000 model the car i always wanted and to take a trip around australia but I am having problems with the 4r100 transmission that was rebuilt before i purchased the truck
The problem and checks. Truck taking of in 3rd can manual select 2nd but not 1st
Getting Codes P0715 , P0717 changed turbine speed sensor checked wiring to pcm all ok codes still coming up
Put truck on scanner and found TSS reading when manually in 2nd but not in park neutral or drive
Removed PTO cover to check gear turning that the TSS reads from with the truck up on stands the gear only turns in 2nd when in park neutral or drive it is stopped verifing what the scanner is seeing the scanner also see the gear changes but the transmission is not changing ...
P0073 Ambient air temperature sensor circuit high. Preliminary inspection, right outside mirror badly damaged/broken. Guess where the sensor is?
View 6 RepliesI 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...
My check engine light popped on for me a couple days ago. P2043-reductant temperature sensor range/performance. Truck still runs like a raped ape, no change in driveability. Just over 21k miles. No "speed limited to 55" messages or anything else. Basically no change in the truck other than the light.
View 12 Repliesi have a 99 f250 7.3 powerstroke. the cam sensor was acting up. that what the scan tool said. i replaced the cam position sensor yesterday, and the truck is still acting up. the motor hitches and will shut off randomly. it tripped the check engine light, and the code is the "cam position sensor" once the truck is warmed up and shut down for like 10 minutes the sensor will not act up anymore. if i just start the truck and run it, even once it is up to tempature it will act up. but if i shut the truck down for about 10 minutes, it goes away. is there something else that could be causing this?
View 14 RepliesI have an new to me 1999 4x4 F350 that I was giving a good once over today on the front end since it wanders a little bit. but anyways I didnt see a abs sensor wire on the front. the plugs are there behind the inner fender well and it looks like there is a plug when the sensor should go in the wheel bearing. was 2 wheel abs an option on these trucks? is there anything else this changes front end wise?
View 14 RepliesI have a 2002 F-250 7.3L with 175,000 miles and it died on me July 30th. Here were the symptoms when it died:
Engine was sluggish at standard RPM about 1300-1500 going about 45 MPH, so I stepped on the gas and it seemed to go away. About another 5 miles down the road and starting from a stop, the same thing started happening. The entire truck seemed like it was going to shake itself apart and with the peddle at half throttle it revved to 3500 rpm and didn't shift into 2nd gear until after about 5 seconds at that RPM. After it jerked into 2nd gear the engine dropped back down to about 1000 RPM and started shaking violently again. At this point I managed to make it to a shopping center and then as soon as I let off the gas (still shaking), the engine dropped to 500 RPM and after about 15-30 seconds shut off. When I got the truck home I managed to start it one more time but it shortly stalled after about 15-30 seconds, again it was hovering around 500 RPM and still shaking badly.
Here is what happens when I try to start it:
From 0-2 seconds, truck goes through a normal cranking rhythm and sound.
From 2-10 seconds, it slowly tries to start itself back up but it sounds like it is only firing on a few cylinders, I'm guessing maybe 2-3.
I stopped after 10 seconds in fear of burning out the starter or killing the batteries.
Troubleshooting:
Removing the connection to the ICP sensor, something I read that might at least let me start the truck, which is how I found the oil on the connection itself. I also noticed a little bit of what looks like oil on the some of the wiring harnesses in the surrounding area. I also checked the fuel bowl and it is filled with fuel.
Possible solutions?:
From what I have read on the forums I am guessing that it has something to do with the ICP or the IPR sensors. I also believe that it is a sensor related issue considering that the truck won't even start. I am completely off track. I am going to start working on it full stride this weekend. I have been vehicle-less since the 30th so I'm trying to get this fixed asap. I don't have any codes, I am going to try to get a coder this weekend.
I am doing some maintenance and trying to replace my EBP tube and sensor. I luckily have the dual alternator package, so getting the tube in and out has been a pain to say the least. I can't for the life of me get the tube back into place. As always, a 20 minute job is taking me 2 days.
View 14 RepliesI cannot locate a picture of where the manual 4wd shifter mounts up to the transmission.
I am finishing up 4wd'ing my F550, but am not exactly sure how the shifter bolts up. Can someone take their boot and bezel off and take a couple photos of how the shifter mounts to the 5R100W by any chanc?
What is the average temp the transmission runs at? Wondering because it slipped the other day and the fluid smelt like it was burnt almost. Wanting to monitor it on my scan gauge and just try to ride it out as long as possible..
View 14 RepliesNoticed a while back that the plug for what I assume is the air intake temp sensor is looped. I assume because I can't find the sensor anywhere. how critical is the sensor? The new S&B has a hole for it so it's either gonna need a new sensor or a plug. The local autozone has one for 16.99.
