Using GST
INSPECTION (USING VOLTMETER)
Standard Value
1. Disconnect the oxygen sensor connector, and measure the resistance between terminal 3 and terminal 4.
NOTE: Before checking, warm up the engine until the engine coolant temperature reaches 80 to 95 °C (176 to 205 °F).
2. Apply battery voltage directly between terminal 3 and terminal 4.
NOTE: Be careful when applying the voltage. Damage will result if the terminals are incorrect or are short circuited.
3. Connect a digital-type voltmeter between terminal 1 and terminal 2.
4. While repeatedly racing the engine, measure the oxygen sensor output voltage.
5. If there is a problem, there may be an oxygen sensor malfunction.
