5		No	Go to the next step.
6	PURPOSE: AIR CLEANER ELEMENT Remove the air cleaner element with the engine is running. (See AIR CLEANER ELEMENT REMOVAL/INSTALLATION [VIN Y] .) Does the engine speed increase?	Yes	Inspect the air cleaner element. (See AIR CLEANER ELEMENT INSPECTION [VIN Y] .) If there is any malfunction: Clean or replace the air cleaner element, then go to Step 13. (See AIR CLEANER ELEMENT REMOVAL/INSTALLATION [VIN Y] .) If there is no malfunction: Go to the next step.
6		No	Go to the next step.
7	PURPOSE: DETERMINE INTEGRITY OF MAP SENSOR Reconnect all disconnected connectors. Inspect the MAP sensor. (See MANIFOLD ABSOLUTE PRESSURE (MAP) SENSOR INSPECTION [VIN Y] .) Is there any malfunction?	Yes	Replace the MAP sensor/IAT sensor No. 2, then go to Step 13. (See MANIFOLD ABSOLUTE PRESSURE (MAP) SENSOR/INTAKE AIR TEMPERATURE (IAT) SENSOR NO. 2 REMOVAL/INSTALLATION [VIN Y] .)
7		No	Go to the next step.
8	PURPOSE: DETERMINE INTEGRITY OF ELECTRIC VARIABLE VALVE TIMING DRIVER Inspect the electric variable valve timing driver. (See ELECTRIC VARIABLE VALVE TIMING MOTOR/DRIVER INSPECTION [VIN Y] .) Is there any malfunction?	Yes	Replace the electric variable valve timing motor/driver, then go to Step 13. (See ELECTRIC VARIABLE VALVE TIMING MOTOR/DRIVER REMOVAL/INSTALLATION [VIN Y] .)
8		No	Go to the next step.
9	PURPOSE: DETERMINE INTEGRITY OF ELECTRIC VARIABLE VALVE TIMING MOTOR Inspect the electric variable valve timing motor. (See ELECTRIC VARIABLE VALVE TIMING MOTOR/DRIVER INSPECTION [VIN Y] .) Is there any malfunction?	Yes	Replace the electric variable valve timing motor/driver, then go to Step 13. (See ELECTRIC VARIABLE VALVE TIMING MOTOR/DRIVER REMOVAL/INSTALLATION [VIN Y] .)
9		No	Go to the next step.
10	PURPOSE: DETERMINE INTEGRITY OF ELECTRIC VARIABLE VALVE TIMING ACTUATOR Inspect the electric variable valve timing actuator. (See ELECTRIC VARIABLE VALVE TIMING ACTUATOR INSPECTION [VIN Y] .) Is there any malfunction?	Yes	Replace the electric variable valve timing actuator, then go to Step 13. (See ELECTRIC VARIABLE VALVE TIMING ACTUATOR, HYDRAULIC VARIABLE VALVE TIMING ACTUATOR REMOVAL/INSTALLATION [VIN Y] .)
10		No	Go to the next step.
11	PURPOSE: DETERMINE INTEGRITY OF OCV Inspect the OCV. (See OIL CONTROL VALVE (OCV) INSPECTION [VIN Y] .) Is there any malfunction?	Yes	Replace the OCV, then go to Step 13. (See OIL CONTROL VALVE (OCV) REMOVAL/INSTALLATION [VIN Y] .)
11		No	Go to the next step.
12	PURPOSE: DETERMINE INTEGRITY OF A/F SENSOR Inspect the A/F sensor. (See AIR FUEL RATIO (A/F) SENSOR INSPECTION [VIN Y] .) Is there any malfunction?	Yes	Replace the A/F sensor, then go to the next step. (See AIR FUEL RATIO (A/F) SENSOR REMOVAL/INSTALLATION [VIN Y] .)
12		No	Go to the next step.
13	PURPOSE: VERIFICATION OF VEHICLE REPAIR COMPLETION Always reconnect all disconnected connectors. Clear the DTC from the PCM memory using the M-MDS. (See CLEARING DTC .)
