SERVICE BULLETIN
APPLICABILITY:	2013MY Legacy and Outback Models
Equipped With 2.5L FB Engine
NUMBER:
DATE:

SUBJECT: D
 ifficulty Starting, Rough Idle, Cam Position or
Misfire DTCs
DTCs P0340, 341, 345 or 346, P0301, 302, 303 or 304
INTRODUCTION
This bulletin will provide an inspection and repair procedure for camshaft position-related and/or
engine misfire DTCs for 2.5L FB engine-equipped 2013MY Legacy and Outback models. 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. The camshaft position sensor clearance may be out of specification
causing these condition(s) and one or more of the DTCs to set.
PART INFORMATION
•
Repair Part Set - 8 Shims/Spacers, p.n. 10130AA060, contains 8 cam position sensor shims,
0.1 to 0.8mm in thickness.
•
Camshaft position sensor o-ring, p.n. 13099AA050 (one time use item - lubricate prior to use).
NOTE: The part numbers shown below are for reference only and cannot be ordered individually.
If a shim is required, the shim kit must be ordered.

SPECIAL TOOLS REQUIRED
•
Pulse/Analog Box, SDI Box and SSMIII						
•
Digital Caliper with depth attachment
•
Flat washer, outside diameter 25.5mm, inside diameter 11.1mm, 7.72mm thick (or equivalent
size. The purpose of the flat washer is to provide a surface for the caliper to rest on while
making the measurements. NOTE: If you have the depth attachment for your digital caliper,
the washer will not be needed.
SERVICE PROCEDURE / INFORMATION
Check the waveforms of the camshaft position sensor using the Pulse/Analog Box, SDI Box and the
oscilloscope function of the SSMIII. For detailed information and instructions, refer to the applicable
Service Manual, SSMIII User’s Guide and Subaru Diagnostic System (SDS). The “Help” function
will allow you to access the tutorial information if needed.
IMPORTANT: When back-probing the ECM connectors to attach the oscilloscope leads, refer to
the wiring schematic for the specific DTC being diagnosed in the applicable Service Manual for
proper connector and terminal locations.

If an abnormal pattern is verified similar to those shown in the illustration above, measure the
clearance between the end of the camshaft position sensor and the sensor plate using the following
procedure. If the oscilloscope pattern is normal, refer to the applicable Service Manual for
additional troubleshooting and diagnostic procedures.
The specified clearance is 1.3 +/- .05mm (1.25 to 1.35mm or .049” to .053”).
•
Record radio station presets (and navigation system favorites if applicable).
•
Disconnect the negative battery cable.
•
Remove the camshaft position sensor from the timing chain cover using the procedure in the
applicable Service Manual.

MEASUREMENTS:
A= Top surface of the timing chain cover to camshaft sensor plate					
B= Camshaft Position Sensor mating surface to the bottom of the sensor
NOTE: When measuring “A”, make sure you are measuring to the outside diameter or “top” of the
sensor plate and not to the bottom of a notch as shown below. Be sure to record all measurements.

IMPORTANT: When using the flat washer, make sure the washer is fully seated on the machined
surface of the timing cover or your measurements will not be accurate.
1. Take a measurement and record the reading
2. Using the breaker bar and 22mm socket, place the socket on the crankshaft pulley bolt and rotate
the engine clockwise approximately 70°. CAUTION: Do not rotate the engine counter-clockwise
as doing so may loosen the crankshaft pulley bolt. If the engine is accidentally turned counterclockwise, make sure the crankshaft pulley bolt is re-torqued to proper specifications.
3. Take a second measurement and record the reading.
4. Rotate the engine clockwise approximately 70° again.
5. Take a third measurement and record the reading.
6. Use the smallest of the three measurements for the “A” value of your shim thickness calculation.

When taking measurement “B”, use a flat steel ruler or equivalent.
Measure the camshaft position sensor mating surface (the area that sits flush on the timing chain
cover) to the bottom of the sensor and record measurement.
IMPORTANT: Be sure to account for the thickness of the flat washer when performing your
calculations to determine the required shim thickness.
The specified clearance is 1.3 +/- .05mm (1.25 to 1.35mm or .049” to .053”).
Example calculation (the 1.72mm thickness of the flat washer is subtracted from “A” measurement):
A= Top surface of the timing chain cover to camshaft sensor plate					
B= Camshaft Position Sensor mating surface to the bottom of the sensor
A) 25.42 – 1.72 = 23.70
A = 23.70
B = 22.58
A – B = 1.12 (clearance)
In this example a 0.2 shim is required.

After the correct shim is selected:
•
Replace the camshaft position sensor o-ring (one time use item - lubricate prior to use).
•
Reinstall the camshaft position sensor and shim.
•
Torque the sensor’s retaining bolt to 6.4 Nm (4.7 ft. lbs. or 56.4 inch-pounds).
•
Reconnect the sensor’s engine wiring harness connector.
•
Reset the radio station presets (and navigation system favorites if applicable).
•
Road test the vehicle to confirm the repairs are complete.
