Keith Browning Posted April 24, 2006 Share Posted April 24, 2006 No big deal, it's a 2002 F-250 with a 7.3L DIT. ICP sensor is leaking oil. The sensor was replaced with a F6TZ-9F838-A part number. The truck left and came back surging and stalling, the tech is not sure what to do. I Look at it, a bunch of ICP codes, checked the sensor for biased readings and the KOEO value was 0.60 Volts! I looked at the sensor and he installed a 6.0L sensor... by looks. The Ford parts hotline says the number is good. The tech hotline says its good. It is the wrong sensor. Anyone run into this? I ordered another in hopes that it was labeled or packed wrong. Quote Link to comment Share on other sites More sharing options...
ktmlew Posted April 25, 2006 Share Posted April 25, 2006 They supposedly use the same sensor since last fall? Quote Link to comment Share on other sites More sharing options...
Keith Browning Posted April 25, 2006 Author Share Posted April 25, 2006 Thanx for the reply, I need as many clues as I can get. I will have another sensor tomorrow. If it comes in the same I will still install it thinking the one in the truck is biased... seriously biased! Quote Link to comment Share on other sites More sharing options...
ktmlew Posted April 25, 2006 Share Posted April 25, 2006 I installed one of the "6.0L" sensors in a 7.3, worked fine. I did have to loosen the lift bracket and shift it's position slightly for clearance. I went back to parts and verified the part # before I put it in...

Keith Browning Posted April 26, 2006 Author Share Posted April 26, 2006 Apparently you and Ford are correct about the sensors superseding. It goes to show how few of those fail on the 7.3L in comparison with the 6.0L. At least for me. Here is what I determined. The tech who repaired the HPOP outlet o-rings and the broken ICP sensor did what most of us might have done, he cleaned up the engine after the repair. I always do. Anyway, he sprayed the engine with a concentrated soap we use for de-greasing and cleaning the floors or used Simple Green and hosed it all down. The customer requested this as well. I found the NEW sensor had fresh corrosion on one of the pins and the connector looked discolored as well. Apparently some soap and water got in the connector and the resulting corrosion and resistance created a biased sensor reading. I replaced the sensor and installed a harness repair pigtail/connector. Runs well again. So... /forums/images/%%GRAEMLIN_URL%%/wink.gif I learned that the sensors are superseded and my tech learned that sometimes WE can cause problems even while doing "the right thing." I have gotten water in that sensor before too but it showed up immediately for me. Live and learn! Quote Link to comment Share on other sites More sharing options...
