0.84. Further, we determined that the ECU was commanding
the B1S1 wide-band sensor's heater at 100 percent all
the time, regardless of what the ECM data stream command
was. We advised the shop of our findings (replace ECM and
front lambda sensor) and returned the vehicle to them. A few
months later, the vehicle returned to us after the repair stating
that the O2 sensor monitor will not complete.
We began our analysis by verifying that our previous
recommendations were performed. A new ECM had been
installed and properly commissioned, and it appeared to have
a new B1S1, but that had also been replaced before the vehicle
visited us on the first trip. We began analysis and immediately
noticed that LTFT was running at about +24 percent
but there were no codes. We then proceeded to connect our
MoTeC LSU4 to the vehicle to sample the exhaust. What we
found was that although the ECM was indicating Lambda 1,
we were measuring 0.94.
We found that the B1S1 sensor was defective. We were
able to pull the video showing the previous results from the
first visit and share them with the shop (Figure 1). We found
that they had not replaced the B1S1 along with the ECU as
recommended which led to this problem.
Having the hard evidence backed up our findings and
went a long way toward smoothing out our relationship. In
our shop, we use shop-ware.com.
TRAINING
We subscribe to many services out there that provide us
with training opportunities and the ability to keep staff up
to date. We use Google Calendar which has a tie-in to Slack
(an internal messaging application all our staff members
subscribe to, and I'll cover more on this subject next) that
brings these notifications to the forefront for all to see. For
example, if we sign up for a webinar, we add it to the training
and education calendar in Google. As soon as this hits, the
Slack API pulls in the notice and lets everyone subscribed to
that channel know. Then on training day, the system delivers
another reminder ping so everyone has easy access to log in
