Pick-Up Coil Resistance Check

  1. Disconnect distributor connector from wiring harness. Connect ohmmeter leads to distributor connector terminals that mate with Orange and Purple wires of control module connector. Measure resistance of pick-up coil then reconnect distributor connector to wiring harness.
  2. On rear wheel drive models, resistance should be 400-1, 000 ohms. On front wheel drive models, resistance should be 650-1, 300 ohms. If resistance is within this range, pick-up coil is OK. If resistance is not within specified range, replace pick-up coil assembly.
