LP5 - Boost Pressure Switch Inspection

Perform Boost Pressure Switch Inspection:

^ Key "OFF".

^ Disconnect the boost pressure switch connector.

^ Apply 71.8-79.8 kPa (10.4-11.6 psi) to the boost pressure switch.

^ Measure the resistance between the terminals of the boost pressure switch.

^ Is the resistance less than 5 ohms between the boost pressure switch terminals with air pressure applied, and greater than 10,000 ohms between the terminals with no air pressure applied?

YES -- Go to LP6. LP6 - Boost Pressure Switch Ground

NO -- Replace the boost pressure switch.
