ON-VEHICLE SERVICE TSB Revision MULTIPORT FUEL INJECTION (MFI) 13A-893 <Right bank heated oxygen sensor (front)> 2 S reading. If values are unsatisfactory, or if a scan tool is not available, (1) Disconnect the heated oxygen sensor connector and connect special tool MD998464 to the connector on the (2) Make sure that there is continuity [4.5 − 8.0 ohms at 20°C (68 °F)] between terminal No. 1 (red clip of special tool) and terminal No. 3 (blue clip of special tool) on the heated (3) If there is no continuity, replace the heated oxygen sensor. (4) Warm up the engine until engine coolant is 80 °C (176°F) or higher. (5) Perform a tracing for 5 minutes or more with the engine speed of 4,500 r/min. (6) Connect a digital voltage meter between terminal No. 2 (black clip of special tool) and terminal No. 4 (white clip of 2. While repeatedly revving the engine, measure the heated oxygen sensor output voltage. Standard value: CAUTION • Be very careful when connecting the jumper wire; incorrect connection can damage the oxygen sensor. • Be careful the heater is broken when voltage of beyond 8 volts is applied to the oxygen sensor heater. NOTE: If the sufficiently high temperature (of approximate ° C or more) is not reached although the oxygen sensor is normal, the output voltage would be possibly low although ENGINE HEATED REMARKS When revving 0.6 − 1.0 volt If you make the − 1.0 volt.
