Required Tool: 10mm Socket, 12V Power Source
04
Test Camshaft Position Sensor

Check 5V reference, ground, and 5V square-wave signal with lab scope or multimeter. on the Mazda MX-5 Miata equipped with 2.0L Skyactiv-G DOHC 16V (181HP / 6-Speed Manual).

Required Tool: Digital Multimeter or Oscilloscope
05
Inspect Timing Chain Tensioner & Marks

If sensor and VVT solenoid test good, remove valve cover to inspect timing chain slack and alignment marks. on the Mazda MX-5 Miata equipped with 2.0L Skyactiv-G DOHC 16V (181HP / 6-Speed Manual).
