A few seconds after ignition switch is turned from OFF to ON: Approx. 294 kPa (2.94 bar, 3.0 kg/cm2, 43 psi)

CHECK EXHAUST GAS SENSOR. (MODELS WITH CATALYZER ONLY) 1. See 'M/R F/C MNT' in 'DATA MONITOR' mode. 2. Maintaining engine at 2,000 rpm under no-load (with engine warmed up sufficiently), check to make sure that the monitor fluctuates between 'LEAN' and 'RICH' more than 5 times during 10 seconds. RICH->LEAN->RICH-> 1 time 2 times LEAN->RICH....... — OR — 1. Set 'Exhaust gas sensor monitor' in the self-diagnostic Mode II. (See page EF & EC-412.) 2. Maintaining engine at 2,000 rpm under no load, check that the RED L.E.D. on the E.C.U. or the check engine light on the instrument panel goes ON and OFF more than 5 times during 10 seconds.
