Component Testing

WARNING: This page is about a different variant/trim than selected.
NOTE: You must perform the Circuit/System Testing in order to verify the integrity of the MAP sensor circuits before proceeding with the Component Testing.
  1. Turn ON the ignition, with the engine OFF, and remove the B74 MAP sensor.
  2. Install a 3 A fused jumper wire between the 5 V reference circuit terminal 1 and the corresponding terminal of the B74 MAP sensor.
  3. Install a jumper wire between the low reference circuit terminal 2 of the MAP sensor and ground.
  4. Install a jumper wire at the B74 MAP sensor signal circuit terminal 3.
  5. Connect a DMM between the jumper wire from the B74 MAP sensor signal circuit terminal 3 and ground.
  6. Install the J 35555:  Metal Mityvac to the B74 MAP sensor vacuum port. Slowly apply vacuum to the sensor while observing the voltage on the DMM. The voltage should vary between 0-5.2 V without any spikes or dropouts.
    • If the voltage is not within the specified range or is erratic, replace the B74 MAP sensor.
