TOOL BRIEFING
Another service regeneration utilizing
the Ultra proved the repair and the
customer was back to work again. It's not
always a high-dollar specialty tool that
gets the job done but rather the right
tool for the job at hand, especially when
it comes to finicky sensors in sometimes
difficult-to-access locations. A small
investment leads to many headaches
saved down the road.
CASE STUDY 3: 2006 FORD
F-350 6.OL - EXTENDED
CRANK/LOW POWER/
INTERMITTENT STALLING
A customer brought this vehicle in with
a complaint of extended crank when
cold and hot as well as low power and
intermittent stalling. A visual inspection
while performing a full system scan with
my Autel Ultra showed major oil leaks
on the top end of the engine as well as a
loose air cleaner assembly. An aftermarket
oil filter cap (tall) was also noted during
this inspection - those of you familiar
with these engines will know that when
one mixes an aftermarket cap with an OE
style filter, issues arise due to lack of proper
compression of the anti-drain back valve in
the filter housing. The information gained
during a visual inspection can be invaluable
when diagnosing a vehicle and putting
together the pieces of the puzzle.
The full system scan reported multiple
DTCs including: P0274:E0 Injector
Circuit High, P0275:60 Cylinder
Contr ibut ion/Balance, P0279:E0
Cylinder 7 Injector Circuit Low, P0528:60
Cooling Fan Speed Sensor No Signal, and
P0470 Exhaust Pressure Sensor. A basic
analysis of the wiring diagrams to get reacquainted
with system layout led me to
the removal of the air cleaner and intake
tube for a further inspection. This revealed
rub-through damage to a main leg of the
wire harness as well as oil damage to the
insulation of the exhaust back pressure
(EBP) sensor harness (Figure 3). Repairs
were made to the wiring harness utilizing
Bluepoint PWC7A wire strippers and a
Milwaukee Tool 2488 cordless soldering
iron and testing continued.

The truck still exhibited a long crank
and low power complaint. Monitoring
scan data confirmed that the system was
struggling to meet the desired minimum
500 psi injection control pressure (ICP)
and that the injection pressure regulator
(IPR) duty cycle was running around 85
percent duty cycle (quite a far cry from
the normal 22 to 28 percent) indicating
either an IPR fault or a major oil leak.
As someone who prefers to gather as
much data with the least amount of effort,
I pulled out two tools to delve deeper
here. The first is an IPR controller, the
44 PTEN OCTOBER 2021 www.VehicleServicePros.com
OTC 6764, that allows me to manually
control the IPR as well as the appropriate
noid light (OTC Noid Light Kit 3054E)
to install into the IPR pigtail of the engine
harness (Figure 4). Scan tool bidirectional
control could be used on it's own
here as but would still requires confirmation
that the signal is reaching the IPR;
this method tests both the solenoid and
the harness/PCM (powertrain control
module) at the same time. The noid light
confirmed that the engine controller's
command was reaching the solenoid and
the IPR controller confirmed that
