NOTE:  Before you troubleshoot, review the general troubleshooting information - Refer to: HOW TO TROUBLESHOOT THE FUEL AND EMISSIONS SYSTEMS or How to Troubleshoot the CVT System(CVT) .

DTCs

1. Clutch pedal position switch installation check:

   - 1. Turn the vehicle to the OFF (LOCK) mode.

   - 2. Check clutch pedal position switches A/C, and B/D installation.

   Is it damaged or loose?

   YES 

   Repair or replace the faulty clutch pedal position switch .

   NO 

   Go to step 2.

2. Clutch pedal position switch signal check:

   - 1. Turn the vehicle to the ON mode.

   - 2. Check CLUTCH PEDAL POSITION SWITCH A, A (C), and D in the DATA LIST with the HDS.

   Signal	Current conditions
   	Values	Unit
   CLUTCH PEDAL POSITION SWITCH A
   CLUTCH PEDAL POSITION SWITCH A (C)
   CLUTCH PEDAL POSITION SWITCH D

   - 3. Press the clutch pedal slowly, and check the value (OPEN or CLOSE) change timing of CLUTCH PEDAL POSITION SWITCH A, A (C), and D, and compare them to the following table.

   CLUTCH PEDAL POSITION SWITCH	Clutch Pedal Release	(slowly pressed)	(slowly pressed)	(slowly pressed)	Clutch Pedal Fully Pressed
   A	OPEN	OPEN	OPEN	CLOSE	CLOSE
   A (C)	OPEN	OPEN	CLOSE	CLOSE	CLOSE
   D	CLOSE	OPEN	OPEN	OPEN	OPEN

   Is the change timing same as the table?

   All signal same as table

   Intermittent failure, the system is OK at this time. Check for poor connections or loose terminals at clutch pedal position switches A/C, B/D, and the PCM. If the freeze data/on-board snapshot of this DTC is recorded, try to reproduce the failure under the same conditions with the freeze data/on-board snapshot.
