code 44

[cotton]

have a code 44 : understand what it is but would like to
eliminate a few basic items: voltage chks ok on the o2 sensors
good fuel pressure; where do go from here: basic problem is
idle: ecm out in calif but they say they cant get a 44 code to read
on the ecm: car is 1992 vette lt1 new owner: been sitting in a
repair shop for last 45 days?? would like to thanks again member
sending me to python injectors // real nice folks. oem ecm has been
on back order for 75 days??

: voltage chks ok on the o2 sensors

As in when logged it shows moving voltage from 0.1 - 0.9V on both O2 sensors?

update/reply

spoke with python a few mins ago and they say a resistor is bad
on the left side o2 sensor??(they are chking and repairing)
garage says I also have a bad ebcm/which needs replacing
I thought when you read a code such as 44(lean??)you had like
a set procedure that you could follow to eliminate and isolate
problem: from what I am reading it appears it can be a lot of
different things___________again thank you for responding
I appreciate it hope to return the favor after I relearn the
shade tree program

People say stuff that means alot, till the sound stops. In other words, means nothing. Get down there, and get them to SHOW you the multimeter hooked up, and shows a resistor that's NOT showing specification current flowing through it.

Ditto for the EBTCM module. Tell them you're from Missouri - that's the 'Show Me' state. Show me the testS that proves bad EBTCM. Note the BOLD 'S', because more than one test is necessary to confirm this UH HUH...

First, clear all codes. See procedure here Then go closed loop (fully warmed up, and do the paper clip gig, found here.

Post back up on it...

pulled out the fsm tonight and put down my regular mind candy
have some values and chk points now: thank you-- will respond
shortly after follow up chks: it appears it can be something as
simple as a ground.??
thanks for your help
