INTRODUCTION
If you encounter a customer complaint that the engine is difficult to start, the camshaft
position sensor air gap may be out of specification. This is caused by an irregular stamping of
the camshaft position sensor plate. To remedy the condition, a shim will need to be added to
the Bank I (right hand) camshaft position sensor to bring the air gap into specification.

!NOTE: DTCs P0341 and P0346 are applicable to 2013MYvehicles only.

PART INFORMATION
• Shim Kit Part Number 10130AA060 contains 8 shims, 0.1 - 0.8mm.

Note: The individual part numbers are listed as a reference only, and can not be ordered.
• Camshaft Position Sensor 0-Ring Part Number 13099AA050 (replace if necessary).
