Power Transistor

1994 Hyundai Sonata Base, 3.0 TSECTION Power Transistor
  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 (positive lead) and No. 5 (negative lead). 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 analog voltmeter, check for continuity between terminals No. 1 (negative lead) and No. 3 (positive lead). With voltage applied to terminal No. 2, continuity should exist. With voltage removed from terminal No. 2, continuity should not exist.

When to See a Mechanic

Stop DIY work and contact a certified mechanic immediately if any of the following apply:

  • • You smell fuel, burning insulation, or see smoke.
  • • Brakes feel soft, pull hard to one side, or make grinding noises.
  • • The engine overheats, stalls repeatedly, or misfires under load.
  • • You are missing required tools, torque specs, or safe lifting equipment.
  • • You are not confident in the next step or safety outcome.
