Oxygen Sensor Heater (Service Code 67) (DTC P0030)
Oxygen Sensor Heater Removal/Installation
  The oxygen sensor heater is built in the oxygen sensor.
So, the heater itself can not be removed. Remove the oxy-
gen sensor (see Oxygen Sensor Removal(16-112)).
Oxygen Sensor Heater Resistance Inspection
• Turn the ignition switch off.
• Disconnect:
  Open  the clamp [A].
• Oxygen Sensor Lead Connector [B]

• Connect  a digital meter [A] to the oxygen sensor lead con-
  nector [B].
• Measure the oxygen sensor heater resistance.
  Oxygen Sensor Heaters Resistance
    Connections: W lead [C] ←→ W lead [D]
    Standard: 13  18 Ω
  If the reading is out of the standard, replace the sensor.
  If the reading is within the standard, check the power
  source voltage (see Oxygen Sensor Heater Power
  Source Voltage Inspection(17-80)).
