MULTIPORT FUEL INJECTION (MFI) DIAGNOSIS TSB Revision MULTIPORT FUEL INJECTION (MFI) <2.4L ENGINE> 13A-459 CAMSHAFT POSITION SENSOR AND Required Special Tools: connect the test harness special tool (MB991348) in 2. Connect the oscilloscope probe to camshaft position sensor connector terminal 5. 3. Disconnect the crankshaft position sensor connector, and connect the test harness special tool (MD998478) in 4. Connect the oscilloscope probe to crankshaft position sensor connector terminal 2 (black clip of special tool). Alternate method (Test harness not available) <M/T> 1. Connect the oscilloscope probe to ECM terminal 50. (Check the camshaft position sensor signal wave pattern.) 2. Connect the oscilloscope probe to ECM terminal 43. (Check the crankshaft position sensor signal wave pattern.) <A/T> 1. Connect the oscilloscope probe to PCM terminal 56. (Check the camshaft position sensor signal wave pattern.) 2. Connect the oscilloscope probe to PCM terminal 45. (Check the crankshaft position sensor signal wave pattern.)
