Boost Sensor Ground Check
- Using an ohmmeter, check for continuity between ground and Black wire at boost sensor 4-pin connector. See IDENTIFYING BOOST SENSOR 4-PIN CONNECTOR illustration. Boost sensor connector is located at turbo boost sensor, near center of firewall.
- If continuity exists between Black wire at boost sensor connector and ground, replace boost sensor. If continuity does not exist between Black wire at boost sensor connector wire and ground, repair Black wire between boost sensor and ground.
