HIGH TENSION WIRE RESISTANCE

Note. High tension lead resistance specification 2.0L Tribute is not available from manufacturer.

Mazda6 (2.3L)

High tension wire resistance should measure

  1. Cylinder No. 1 - 5900-13,600 ohms
  2. Cylinder No. 2 - 4900-11,500 ohms
  3. Cylinder No. 3 - 3800-8900 ohms
  4. Cylinder No. 4 - 3600-8500 ohms

Miata

Miata uses coil on plug configuration on cylinders No. 2 and 4. High tension lead for cylinder No. 1 should measure 5000-13,000 ohms. High tension lead for cylinder No. 3 should measure 1500-4000 ohms.

Protege & Protege5

Protege & Protege5 uses coil on plug configuration on cylinders No. 2 and 4. High tension lead for cylinder No. 1 should measure 5600-12,100 ohms. High tension lead for cylinder No. 3 should measure 1900-4000 ohms.
