Does this CAT pigtail have the metal clip that locks the connector in place or the plastic tabs on the side? For some silly reason I trust the metal ones more for this application. I cant tell you why but I do. If it really does not matter there is a Ford connector that will work on injectors, the IPR and the VGT actuator... let's see if I can dig the # up I knew we went over this before. Try 6e7z 12a690-da which is the last good number I found for the IPR connector which has the plastic side tabs but it works.

I shit you not! I took an ATX case, put an ASUS CUV40 motherboard - 133 Mhz bus, 733 Mhz Pentium 3 processor, 18gb hard drive, 520 Mb RAM and an ATI Radion 128 video, Soundblaster 16 sound card and a CD-RW drive. It has been slowing down with some of the newer applications I have in it now but it WORKS! I have an external hard drive I use to back up my data. Me thinks it is time to replace it before I start pushing my luck.

I was wondering what the typical life expectancy of a PC for most people. Considering that my main PC (the one I created and maintain the DTS site with) is now 10 years old the idea of replacing it has again crossed my mind. This is a machine that I built so actually it is just the computer itself that is that old. It started with a hand me down monitor, keyboard and mouse from the only complete system my wife and I have ever purchased. Since then all of that has been replaced I have added a second hard drive and a DVD burner. The only failure I have had to repair was the power converter. I Googled computer life expectancy and did some reading to discover that the typical average is 3 to 5 years. If you are an avid gamer the time is 1 to 2 years!

Done and done. (just in case it disappears)

Yes! The file attachment issue was fixed last week and tested.

These trucks can get pretty hairy when it comes to diagnosing anything that uses shared data and I was hoping you would find something simple. I had some early 2007 F750's that had harness issues. Getting help from CAT was easy, Ford had no information and Allison would not even talk to us because we are not an Allison service center. Harnesses? Tight? I changed 5 harnesses in affected trucks. They are not only tight but they use an obscene number of zip ties to secure them.

It would be great to hear more on this from an engineer that actually has the answer. It seems the more I go looking for answers the more questions I have. I had one additional thought for us to chew on. I have yet to see an IAT2 sensor that didn't have carbon packed around the thermistor and I question the impact of that carbon on the sensor's ability to react to temperature changes quickly or it's accuracy for that matter.

Cool! It has been a while since we have had a spirited technical discussion. It seems that there are indeed inconsistencies regarding descriptions of the function of the IAT2 sensor for 6.0L engines. I would even say there are some outright vague statements too. This supports Bruce's point about manuals. I have listed the most relevant ones I have found thus far. I am sure there are more. Only the OBD System Operation manual mentions EGR in relation to IAT2 - cooler efficiency to be exact. There are other monitors and sensor checks requiring a valid IAT2 signal however. Here are some printed statements regarding IAT2: 2003 PCED 6.0L [*]The IAT2 sensor is located in the intake manifold. The sensor provides a manifold air temperature signal to the powertrain control module (PCM). 2007 PCED 6.0L [*]The IAT2 sensor is located in the intake manifold. The sensor provides a manifold air temperature signal to the PCM. The PCM uses the IAT2 signal to control timing and fuel rate during cold starts and provide an input to the cold idle kicker. 2003 MY OBD System Operation Summary for 6.0L Diesel Engine [*]Typical Intake Air Temperature 2 Rationality Check Entry Conditions: P0096 - initial Oil Temperature (EOT) is less than 40 deg C. . [*]Typical Intake Air Temperature 2 Rationality Check Malfunctions Thresholds: P0096 - When the change in Intake Air Temperature 2 (IAT2) is less than specified (5 deg C), the drive cycle increment counter advances. 2007 MY OBD System Operation Summary for 6.0L Diesel Engine- [*]Typical Exhaust Gas Recirculation (EGR) Cooler Efficiency Monitor Thresholds: P2457 – Fault sets if IAT2 > 85 deg .C (F series), > 95 deg. C (E series) 2003.25 6.0L Coffee Table Book [*]The primary function of the IAT2 sensor is to provide a feedback signal to the PCM indicating manifold air temperature. . [*]The PCM monitors the IAT2 signal to determine if the temperature is satisfactory. . [*]During engine operation, if the PCM recognizes that the IAT2 signal is lower or higher than the expected value it will set a Diagnostic Trouble Code (DTC) and illuminate the amber malfunction indicator lamp on the dash. MY OPINION is that IAT2 has no direct role in EGR operation, control or (feedback relative to control.) You have an EGR position sensor providing direct EGR valve position feedback and the EBP, MAF and MAP sensors are used to calculate the EGR flow rate and for concern detection. MY EXPERIENCE has been that I have never had a concern with the IAT2 or and EGR concern where diagnostic tests so much as mention IAT2. As mentioned, I have been taught that using IAT2 data can help identify an EGR efficiency concern using data logger. In fact, I have diagnosed a few CLOGGED EGR cooler/ports that had no DTC's in memory and only one failed the IDS-EGR test because it was totally blocked. The others kept spitting pebble-sized pieces of carbon into the valve hanging them up. I am willing to learn more...

This product is something your used car dept. could benefit from. These days with used cars being more valuable than ever clearing up those headlights can make an okay used car sparkle a little not to mention passing inspection. In NJ you can fail DMV inspection if the lenses are too funky. I would guess that most other states are similar, no?

I can see how you might come to that conclusion Clark however the IAT-2 sensor has no correlation with EGR operation other than it's reading "can" be used but a technician to verify that EGR is flowing during a road test. Under load with EGR flowing you could expect to see a 100* increase when the EGR valve is opened. According to the PCED the PCM uses the IAT-2 signal to control timing and fuel rate during cold starts and to provide an input to the cold idle kicker. I recall asking an engineer about this sensor back when we took note that these sensors coke up who confirmed this information. It's failure or contamination has no effect on EGR flow nor will it cause an EGR cooler to overheat or cause coolant to boil in the EGR cooler.

Sorry for your loss Larry - When my dad passed he had been dealing with the worsening effects of emphysema and constant respiratory infections for the better part of two years. He finally got to a point where I believe he decided he had enough and stopped taking his medications and passed soon after. It sounds strange but some people are able to accept death and deal with it on their terms. For me it was easier to take that way I suppose. Sounds like our Mum had her terms as well. Peace be with you my friend.

FSE'w would be correct. I thought that sounded odd.

Yep. But let us hope these things hold together. Bosch will be the injector supplier too...

I got similar info from my FSE and the conversation began with labor times being much lower compared to the 6.4L. To add to your list the valve covers and the intake manifolds are integrated and the oil cooler is externally mounted on the block. The odd thing was he said "they" were not sure who was making the transmission. Not sure exactly what that meant considering the engine is slated for production in 6 months or less. What trans is in the test mules?

I am sure we all do Bruce but I personally haven't got much in the way of notes as far as these specific circuits are concerned. As a side note, (no pun intended) I think any good tech is thinking about what he is testing and what he expects to see and why. I will try to keep this on the fore-front of my mind as I go about my work... Unfortunately my dealership does not have the BOB adapters for these PCM's and taking actual readings off of the circuits is difficult to say the least when trying to back probe the connectors as I am sure you well know. Shit, scoping the CMP and CKP sensors has been a freaking circus act every time I need to do so. I have asked for the tool in the past but it still has not appeared on my workbench and with things the way they are at the moment it doesn't look like I will be seeing it any time soon. I am very surprised it is not an Essential Service Tool.

Another fine example of union intervention keeping things from getting done. Fred, what town was this anyway?

I apologize for bringing this back on-topic but did anybody ever find out if there are translated versions of these documents?

Does that mean we can't get rippin drunk, stick roman candles in out butts and light them off? Not that I would do that of course. Happy Dependence Day!

Thanx fellas! I don't know what is going on with my parts dept. on this one. I saw the picture for the converter and it showed the nuts but did not have any number or label for them to get a part #

Anyone have the part number for Torqshift torque converter nuts? Any year will likely do but this is a 2007 LCF if it matters.

Personally I think ALL diesel claims are being reviewed at this time.

$80 is still a lot cheaper than new lamp assemblies. My dealer started selling those a month ago too. I haven't done any but I watched the demo and it actually turned a foggy lens clear and shiny
