EC-862 [QG (WITHOUT EURO-OBD)] HO2S2 (M/T MODELS) Specification data are reference values and are measured between each terminal and ground. CAUTION: Do not use ECM ground terminals when measuring input/output voltage. Doing so may result in dam- Diagnostic Procedure EBS00R2L 1. CHECK OVERALL FUNCTION-I 1. Start engine and warm it up to the normal operating temperature. 2. Turn ignition switch “OFF” and wait at least 10 seconds. 3. Start engine and keep the engine speed between 3,500 and 4,000 rpm for at least one minute under no 4. Let engine idle for one minute. 5. Set voltmeter probes between ECM terminal 16 (HO2S2 signal) and ground. 6. Check the voltage while revving up to 4,000 rpm under no load OK or NG OK >> INSPECTION END NG >> GO TO 2. 2. CHECK OVERALL FUNCTION-II Keep engine at idle for 10 minutes, then check the voltage between OK or NG OK >> INSPECTION END NG >> GO TO 3. TER- MINAL NO.
