Check exhaust gas sensor. • Run engine at approximately 2,000 rpm after warm-up. • Conduct "MIXTURE RATIO" test with "FUNCTION TEST" showing on display or proceed as follows: • Select "EXH GAS SEN" with "DATA MONITOR" showing on display. • Run engine at 2,000 rpm under no load after warm-up. Check to ensure display alternately shows "LEAN" and "RICH" at least 5 times within 10 seconds. RICH→LEAN→RICH→LEAN→RICH... (← 1 time → ← 2 times →) • Set body-side diagnostic connector (inside fuse box) in "Exhaust gas sensor monitor" mode. (Refer to "Self-Diagnosis".) • Run engine at 2,000 rpm under no load after warm-up. • Check to ensure RED L.E.D. on E.C.U. flashes at least 5 times within 10 seconds.
