2、LE2006 Civic Technical Information GuideElectronic Fuel and Emission Control System - OverviewThe electronic fuel and emission control system of the 2006 Civic incorporates the following improvements: Enhanced system performance. Contributing factors are increased processing capacity of the CPU, hig
3、her ROM capacity, and optimized ETCS configuration. Additional torque management control items for maximum driving comfort and stability control. These include absorption of torque difference resulting from VTECs switching to the delayed intake valve closure mode and coordination with the vehicle st
4、ability assist (VSA) control. Highly precise intake airflow control. Mass air flow (MAF) is used in conjunction with a sensor for manifold absolute pressure (MAP) in order to improve idling operation control. Use of a linear air fuel (LAF) sensor together with an O2 sensor, PRISM (Prediction and Ide
5、ntification Sliding Mode) control consisting of cylinder-by-cylinder feedback control, and an MAF and MAP combination for more accurate estimation of intake airflow. This system provides highly precise air/fuel control for better fuel efficiency as well as lower emissions. Improved exhaust temperatu
6、re management control. This consists of engine firing control for quick engine warm-up and consequent earlier activation of the catalyzer located below the exhaust manifold. Improved temperature estimation accuracy of the O2 sensor element is another factor permitting earlier determination of cataly
7、zer activation. Exhaust gas recirculation control not only for lowering the exhaust temperature, but also takes increased advantage of the stoichiometric zone by improving fuel economy and NOx reduction. Advanced temperature management control applied to the catalyzer below the exhaust manifold. Opt

10、a pulsar plate that is secured with three bolts to a crankshaft weight inside the crankcase. Increased installation accuracy ensures that all misfire patterns are detectable. Since all misfire patterns are detected, the cylinder most damaging to the catalyzer can now be identified and its fuel suppl

Even after recovery from a failure, the MIL continu

If misfiring repeatedly occurs in another driving cycle, the MIL continuously flashes, fuel supply to the cylinder remains interrupted until the ignition switch is turned OFF, and the correspond
13、ing DTC is set. When the ignition switch is returned to ON in the next driving cycle, the MIL comes on indicating misfiring has occurred, and this state continues until the DTC is erased. If no other misfire occurs after a transient DTC has been set, the DTC is automatically erased from the memory a
