Power Transistor (1.6L & 2.0L)

  1. Disconnect connector from power transistor. To check power transistor for cylinders No. 1 and 4, apply 1.5 volts between power transistor terminals No. 3 (negative) and No. 4 (positive). See Fig 1 .
  2. Using analog ohmmeter, check continuity between terminals No. 3 and 5. With voltage applied to terminal No. 4, continuity should exist. With voltage removed from terminal No. 4, continuity should not exist.
  3. To check power transistor for cylinders No. 2 and 3, apply 1.5 volts between power transistor terminals No. 2 (positive) and No. 3 (negative). Using an analog voltmeter, check for continuity between terminals No. 1 and 3. With voltage applied to terminal No. 2, continuity should exist. With voltage removed from terminal No. 2, continuity should not exist.
