Fig. Fig. 2: Backprobe terminals 2 and 3 as shown; touch the tip with a screwdriver, and then quickly pull away while measuring voltage

  1. Remove the sensor from the engine.
  2. Inspect the sensor tip. If damage to the tip is evident, replace the sensor.
  3. Plug in the sensor, but do not install it .
  4. Backprobe terminals 2 and 3 with a voltmeter. Using a screwdriver, touch it against the sensor core.

The voltmeter should read approximately 5 volts.

  1. Slowly pull the screwdriver away; the meter should remain at 5 volts.
  2. Touch the sensor core with the screwdriver; then quickly draw it away. The voltage should drop to approximately 0 volts.
  3. If the sensor does not respond accordingly, the sensor may be faulty.

REF Sensor

Fig. Fig. 4: Measure the resistance between the two terminals to check for proper operation

  1. Measure the resistance between the two terminals on the sensor.
  2. Resistance between the terminals should be approximately 470-570 ohms @ 68°F (20°C).
