Boost Gauge Check
- Disconnect boost gauge sensor connector. Boost valve connector is located at turbo boost sensor near center of firewall.
- Place jumper wire between Yellow/Blue wire at instrument cluster 8-pin connector and Light Green/Red wire at instrument cluster 18-pin connector. See Figure and Fig 1 . Instrument cluster 8-pin and 18-pin connectors are located on right side of dash, near steering column.
- Observe boost gauge reading. If boost gauge reads full scale, replace boost sensor. If boost gauge does not read full scale, replace boost gauge.
