CHECK INTERMITTENT INCIDENT GI-37, "Intermittent Incident" . >> INSPECTION END Component Inspection INFOID:0000000007358574 HEATED OXYGEN SENSOR 2 With CONSULT 1. Turn ignition switch ON and select “DATA MONITOR” mode with CONSULT. with CONSULT. 7. Check “HO2S2 (B1)/(B2)” at idle speed when adjusting “FUEL INJECTION” to ± 25%. “HO2S2 (B1)/(B2)” should be above 0.58 V at least once when the “FUEL INJECTION” is + 25%. “HO2S2 (B1)/(B2)” should be below 0.18 V at least once when the “FUEL INJECTION” is − 25%. CAUTION: • Discard any heated oxygen sensor which has been dropped from a height of more than 0.5 m (19.7 in) onto a hard surface such as a concrete floor; use a new one. • Before installing new heated oxygen sensor, clean exhaust system threads using Oxygen Sensor Thread Cleaner [Commercial service tool (J-43897-18 or J-43897-12)] and approved Anti-seize Lubri- cant (Commercial service tool). Without CONSULT 1. Start engine and warm it up to the normal operating temperature. nal] and ground. 6. Check the voltage when revving up to 4,000 rpm under no load at least 10 times. (Depress and release accelerator pedal as soon as possible.) The voltage should be above 0.58 V at least once during this procedure. The voltage should be below 0.18 V at least once during this procedure. If the voltage can be confirmed at step 6, step 7 is not nec- essary. JMBIA0605GB PBIB2054E August 2012 2012 Pathfinder |
