Test 14: Air Temperature Sensor

  1. Check electrical connections on sensor. Use L-Jetronic test 4 to check Air Temperature Sensor values. If values are incorrect, remove connector from sensor and attach volt/ohmmeter. Check resistance between terminals 22 and 6 and compare with table. See AIR TEMP. SENSOR RESISTANCE SPECIFICATIONS  table.
  2. If resistance values are correct, trace sensor circuit and repair wiring. If values are incorrect, replace Air Flow Sensor.
