Component Testing

IMPORTANT: You must perform the Circuit/System Testing before proceeding with the Component Testing.
  1. Ignition OFF, remove the MAP sensor.
  2. Install a 3-amp fused jumper wire between the 5-volt reference circuit terminal C of the sensor and 5 volts.
  3. Install a jumper wire between the low reference circuit terminal A of the sensor and ground.
  4. Install the J 35555  to the MAP sensor vacuum fitting. Slowly apply vacuum to the sensor while monitoring the voltage between the signal terminal B and the low reference terminal A. The voltage should vary between 4.9-0.2 volts without any spikes or dropouts.
    • If the voltage is not within the specified range or is erratic, replace the MAP sensor.
