I'd send this to another group...but I don't know who is abominable and who
is not (know what I mean?) I've followed and contributed to this group for
some time and would prefer to ask the question here. Thanks in advance.
Please forgive me for asking about a Buick....but I need help with my
barber's Buick. I'm due for a haircut and this will be my third one without
an answer on his trouble. Over the Christmas holidays he told me he was
having trouble starting the engine cold. He had a buddy check it and found a
bad camshaft sensor....so replaced. But it is still reporting 26
(quad-driver) and the 41 cam sensor. I cleared the codes, started the
engine....and 26 and 41 returned. The engine runs good once started. It is a
91 Buick with 3.8 "C" engine. Do you think it is another bad cam sensor or
does the quad-driver in the PCM bad? Any help would be appreciated. Below is
a reminder of the code definitions.
26 Quad-Driver sense voltage shows a low voltage when battery voltage should
be present, or if the sense voltage shows battery voltage when a low voltage
should be present for at least 5 seconds when the engine was running.
41 Cam sensor signal was not received by PCM for the last 5 seconds while
engine was running.
