EC-652 < COMPONENT DIAGNOSIS > [VK56DE] P0137, P0157 HO2S2 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-III 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. 7. Keep vehicle at idling for 10 minutes, then check voltage. Or check the voltage when coasting from 80 km/h (50 MPH) in the D position. 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. 8. If NG, replace heated oxygen sensor 2. 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).
