Boost Sensor Output Check No. 2

  1. 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.
  2. 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.
