Component Test

IMPORTANT: You must perform the Circuit/System Testing before proceeding with the Component Testing.
  1. Turn ON the ignition with the engine OFF, and remove the affected sensor.
  2. Install a 3A fused jumper wire between the 5-volt reference terminal of the sensor and 5-volt reference.
  3. Install a jumper wire between the low reference terminal of the sensor and ground.
  4. Install a jumper wire at the signal terminal sensor.
  5. Connect a DMM between the jumper wire from terminal of the sensor and ground.
  6. Install the J 35555  to the sensor vacuum port. Slowly apply vacuum to the sensor while monitoring the voltage on the DMM. The voltage should vary between 0-5.2 volts, without any spikes or dropouts.
    • If the voltage is not within the specified range or is erratic, replace the affected sensor.
