well the past problems i have had with the engine have come back since the last post i did ( iac ohms test ) ....iac is fine
last night i removed all the sensors off the engine and went over each of them ...cleaned,meter tested . also during all this i had the batt disconnected all night to make sure the computer was blank when i re-install everything . put every thing back and started the truck and took it for a test drive around the subdivision .before i started this the cel came on then i did the removel of stuff .....going around the block i got another cel and so i figured i would do another code test and this is what i got ( useing " I " for explaining purposes.....
III III I III II IIIIIII III II IIIIIII , this is what i have come up with,
first code is 33 ( 1 is a spacer )
second code is 327 ( is displayed twice )
the only egr sensor i did not replace a year ago was the egr postion sensor .i meter tested it and got 33 ohms ( withen spec ) ,but the harness hada bad wire connector ...i figured that may have been my problems but i fixed it but no luck.
the codes point to the egr solinoid / dpfe module .i know that the dpfe gets it's signals from the exhaust then sends that info either to the pcm or directlly to the egr postion sensor it's self ( foot bone connected to the ankle bone ) .
the dpfe was replaced a year ago so it somewhat new but the egr solinoid is the one from the factory .i think i have read in another post that the dpfe module was notoriuos for going out could that be the source of the cel or is the egr solinoid( even tho it tested ok ) ,i was kinda confused on the test procedure in my haynes manual for the dpfe module .
any advice would be greatly appreciated ...........
edit : the numbers i typed under the " I 's " did not match up to them when i posted ( i deleted them to cut down on confusion )
