Code 33: Vehicle Speed Sensor No. 2

NOTE: Refer to illustration for ECU connector and terminal identification. See Figure .
  1. Remove instrument cluster assembly. Measure resistance between connector terminals No. 11 and 8 of combination meter while rotating speedometer cable rotor with screwdriver. See Fig 1 . If resistance switches from greater than one megohm to less than 10 ohms (4 times per revolution), go to next step. If resistance does not switch as indicated, replace combination meter.
  2. Turn ignition off. Disconnect ECU connector. Measure resistance between ECU connector E29, terminal No. 4 and instrument cluster connector terminal No. 8. See Fig 2 . Less than 10 ohms should be present. Measure resistance between instrument cluster connector terminal No. 4 and ground. At least one megohm should be present. If resistances are as specified, repair or replace harness connector. If resistances are not to specification, go to next step.
  3. Measure resistance between instrument cluster connector terminal No. 8 and ground. If resistance is not at least one megohm, repair or replace harness connector. If resistance is not to specification, repair ECU harness connector or replace ECU.
