id010245100300
• The detection condition of the following DTC has been changed from 2007MY. P2004 Variable tumble shutter valve stuck open • PCM monitors variable tumble shutter valve position using variable tumble shutter valve switch. If PCM turns the variable tumble solenoid valve on but variable tumble shutter valve position still remain open (variable tumble shutter valve switch off), PCM determines that variable tumble shutter valve has been stuck open. P2006 Variable tumble shutter valve stuck closed • PCM monitors variable tumble shutter valve position using variable tumble shutter valve switch. If variable tumble turns variable tumble solenoid valve off but variable tumble shutter valve position still remain close (variable tumble shutter valve position sensor on), PCM determines that variable tumble shutter valve has been stuck closed. P2009 Variable tumble solenoid valve circuit low input • The PCM monitors variable tumble solenoid valve control signal. If the PCM turns variable tumble solenoid valve off but voltage still remains low, the PCM determines that variable tumble solenoid valve circuit has a malfunction. P2010 Variable tumble solenoid valve circuit high input • The PCM monitors the variable tumble solenoid valve control signal. If the PCM turns variable tumble solenoid valve on but the voltage still remains high, the PCM determines that the variable tumble solenoid valve circuit has a malfunction.

ON-BOARD DIAGNOSTIC [LF] KOEO/KOER SELF-TEST [LF]
id010245100400
• The self-test function consists of the KOEO (Key On Engine Off) self-test, performed when the ignition switch is turned to the ON position and the engine is stopped; and the KOER (Key On Engine Running) self-test, performed when idling. If a malfunction is detected when either self-test is executed, a DTC is displayed on the Mazda Modular Diagnostic System (M-MDS). Using the self-test function, the present malfunction or a successful repair is readily confirmed. Refer to the self-test function table for the corresponding DTCs. KOEO (Key ON, Engine Off) Self-test • The KOEO self-test is a powertrain control system self-diagnosis, performed when the ignition switch is turned to the ON position and the engine is stopped. A KOEO self-test begins when the connected Mazda Modular Diagnostic System (M-MDS) sends an execute command to the PCM. • As the KOEO self-test is performed, the PCM performs the inspection for set DTCs and if a malfunction is detected the DTC is displayed on the Mazda Modular Diagnostic System (M-MDS). KOER (Key ON, Engine Running) Self-test • The KOER self-test is a powertrain control system self-diagnosis, performed when the ignition switch is turned to the ON position and the engine is idling. A KOER self-test begins when the connected Mazda Modular Diagnostic System (M-MDS) sends an execute command to the PCM. • As the KOER self-test is performed, the PCM performs the inspection for set DTCs and if a malfunction is detected the DTC is displayed on the Mazda Modular Diagnostic System (M-MDS).

AT • The variable tumble system functions to lower emissions at cold-engine start. • At cold-engine start, the variable tumble system increases intake airflow speed by closing the shutter valve and narrowing the intake passage. As a result, the air-fuel mixture quality from the injector is improved. Additionally, the creation of a powerful air tumble in the combustion chamber promotes the atomization of the air-fuel mixture. Due to this, exhaust emission efficiency is improved. • For the variable tumble control, refer to CONTROL SYSTEM, Variable Tumble Control. (See 01-40-8 VARIABLE TUMBLE CONTROL OUTLINE [LF].) (See 01-40-8 VARIABLE TUMBLE CONTROL BLOCK DIAGRAM [LF].) (See 01-40-9 VARIABLE TUMBLE CONTROL OPERATION [LF].)

AT Engine speed less than 3,750 rpm and engine coolant temperature less than 63 °C {145 °F} (variable tumble shutter valve is closed) • Intake manifold vacuum is applied to the variable tumble shutter valve actuator by the operation of the variable tumble solenoid valve, closing the variable tumble shutter valve. At this time, the VARIABLE TUMBLE SHUTTER VALVE CLOSED intake passage is narrower than normal, increasing intake airflow speed and also creating a powerful air tumble in the combustion chamber.

AT Construction • Mainly composed of the solenoid coil, spring, and plunger. Operation Energized • The solenoid coil magnetizes, pulling the plunger. The passage between A and B ports opens due to the plunger being pulled, and intake manifold vacuum is applied to the actuator. Not energized • The intake manifold vacuum passage is blocked, and the passage between ports B and C opens, depressurizing the actuator. ENERGIZED

Operation conditions • When all of the following conditions are met, the PCM energizes the coil of variable tumble solenoid valve. As a result, negative pressure is introduced to the diaphragm chamber of the variable tumble shutter valve actuator, pulling the actuator rod and closing the variable tumble shutter valve. — Engine speed less than 3,750 rpm — Engine coolant temperature less than 63 °C {145 °F} — Throttle valve opening angle is at the specified value or less (changes according to engine speed) Inhibition conditions • When a DTC for the ECT sensor or TP sensor has been stored, the variable tumble control is inhibited and the variable tumble shutter valve is constantly open.

Description When the ignition switch is turned to the ON position, the main relay turns on. The drive-by-wire control calculates the optimum target throttle valve opening angle at all ranges of engine speeds and controls the throttle valve actuator. Supplies power to the drive-by-wire control. Switches energization of the variable shutter valve actuator according to engine speed to enhance the inertia charging effect. At cold engine start, the following effects occur due to the closing of the variable tumble control for improved cold engine emission performance. • Improved intake airflow speed near injectors • Strong air tumble occurs in the combustion changer, promoting vaporization mixture of intake air and fuel Changes the intake valve timing according to engine operation conditions to improve engine output, fuel economy and exhaust emission performance. Performs optimum fuel injection according to engine operation conditions. Performs energization of the fuel pump relay only when the engine is running (operates fuel pump) to improve stability and durability. Controls ignition to optimum timing according to engine operation conditions. An appropriate amount of evaporative gas is fed into the dynamic chamber by the driving of the purge solenoid valve according to the engine operation conditions to ensure driveability and prevent release of fuel vapor gas into the atmosphere. Adjusts the EGR to the optimum opening angle according to engine operation conditions. Based on the control of the front and rear HO2S heater, a stabilized oxygen concentration is detected even at low exhaust gas temperature and feedback control of fuel injection even during cold engine start is made possible for improved cold temperature emission performance. The current application (energize/non-energize) to the A/C relay (magnetic clutch) is controlled according to the engine operation conditions to prevent deterioration of engine performance, damage to the engine, and deterioration of the A/C function. Through cooling of the radiator and condenser by operation of the cooling fan according to vehicle conditions, engine reliability and cooling performance have been improved. Theft deterrence has been improved by controlling energization to the starter relay according to an engine stop request signal from the immobilizer system. Generator output is optimized according to the engine operation and electrical load conditions, ensuring idling stability and anti-load performance. Used for communication with the EHPAS control module, ABS HU/CM, instrument cluster and DLC-2.
