Boost Sensor Ground Check
- Using an ohmmeter, check for continuity between ground and Black wire at boost sensor 4-pin connector. See Figure . Boost valve connector is located at turbo boost sensor near center of firewall.
- Observe ohmmeter reading. 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 valve connector wire and ground, repair Black wire between boost sensor and ground.
