ENGINE GENERAL INFORMATION AND DIAGNOSIS (H27 ENGINE) 6-1-23
FAIL SAFE OPERATION
• Injector drive time (fuel injection volume) is determined according to
throttle valve opening and engine speed.
• EGR valve stops.
• Air flow of IAC valve is limited.
Each control is performed on the basis of 22.1°C intake air temp.
• Each control except 4-A/T is performed on the basis of 29.9°C engine
coolant temp.
• 4-A/T control is performed assuming 31°C (engine warmed up) or
higher after 15 min. from engine start.
• Each control except 4-A/T is performed on the basis of 124.5° throttle
valve opening.
• 4-A/T control is performed on the basis of 0° throttle valve opening.
Air flow of IAC valve is limited.
Each control is performed based on 760 mmHg barometric pressure.
A/T control is performed in priority order of L, 2, N, D, R and P.
A/T control is performed by using signal from VSS.
• A/T control using 3rd gear is performed when D range, 1st, or 2nd
gear is used.
• TCC solenoid OFF
• A/T control using 4th gear is performed when D range, 2nd or 3rd
gear is used.
• When both shift solenoids A (#1) and B (#2) failed simultaneously,
A/T control using 4th gear is always performed in D range.
• TCC solenoid OFF
TCC (Lock-up) solenoid OFF
