Boost Sensor Output Check No. 2
- Using a voltmeter, check for 2-3 volts on Light Green/Yellow wire at boost sensor 4-pin connector. See IDENTIFYING BOOST SENSOR 4-PIN CONNECTOR illustration. Boost sensor 4-pin connector is located at turbo boost sensor, near center of firewall.
- Observe voltmeter reading. If voltage reads 2.5 volts, go to BOOST GAUGE CHECK. If voltage does not read 2.5 volts, repair Light Green/Red wire between gauges and boost sensor.
