INTRODUCTION
This Bulletin provides inspection and repair procedures for intake and exhaust camshaft
position-related and/or engine misfire DTCs for the FA and FB engine-equipped models listed
above. The camshaft position sensor (CPS) clearance may be out of specification causing
these condition(s) and one or more of the DTCs listed above to set. In addition to a Check
Engine light coming on, there may or may not be customer concerns of rough idle, extended
cranking or no start.
NOTES:
• This Service Bulletin will replace Bulletin numbers 11-100-11R, 11-122-12,
11-124-12R and 11-125-12.
• Read this Bulletin completely before starting any repairs as service procedures
have changed.
• An exhaust cam position sensor clearance out of specification will NOT cause a
startability issue.

•

Digital Caliper with depth attachment or 1” Depth Micrometer

•

If you do not have a depth attachment or a 1” Depth Micrometer, use a flat washer,
(outside diameter 25.5mm, inside diameter 11.1mm, 7.72mm thick) or equivalent.
The purpose of the flat washer is to provide a surface for the caliper to rest on while
making the sensor clearance measurements.

SERVICE PROCEDURE / INFORMATION
The Service Procedure of this Bulletin will have 2 sections, one for the intake cam position
sensors and a second for the exhaust.
Check the waveforms of the applicable sensor (intake and / or exhaust) using the Pulse/
Analog Box, SDI Box and the oscilloscope function of the SSMIII. For detailed information
and operating instructions, refer to the applicable Service Manual or the Subaru Diagnostic
System (SDS) SSMIII User Guide. Click on “Help” at the top of the SSMIII Main Menu
screen for the User Guide and additional helpful information.
When diagnosing an extended crank and / or a no start condition as outlined in this Bulletin,
check the wave forms of the crank position and cam position sensors as follows:
•

For FA and FB NA engines: Crank Position and Intake Cam Position (left & right)

•

For FA Turbo engine: Crank Position along with Intake and Exhaust Cam Position
(left & right)

IMPORTANT: When back-probing the ECM connectors to attach oscilloscope leads,
refer to the wiring schematic for the specific DTC being diagnosed in the applicable Service
Manual for proper connector and pin terminal locations.
Understanding the Relationships between the Crank and Camshaft Position Sensors
When setting up your oscilloscope to check Camshaft Position Sensor data, also select the
Crankshaft Position Sensor data to help your understanding. It is important to arrange your
selections in the order shown in the following screen shot examples. The Crank sensor
data will make it easier to establish the firing order and identify cam sensor waveform
inconsistencies. Example 1 on the next page is a perfectly normal pattern for all 3 sensors.
Let’s look at some specifics of the data which will help you determine a “good” pattern versus
a “bad” one.
Looking at the crank signal on page 4, you will see the difference between what we will call
“1’s” (a single spike) and “2’s” (a double spike). This helps establish the engine’s firing
order and what the corresponding cam sensor data should look like. The ECM looks for
the “Edges” of the cam position sensor voltage drops to be within specified time “Window”
parameters. The chart below Example 1 on the next page will help bring this all together.
(Range was set to 250 msec / div. so the crank signal would be easier to understand here.)
