Component Inspection

■ Accelerator Pedal Rod Inspection 

1. Verify that the accelerator pedal operate freely without binding between full closed and wide open position by operating the accelerator pedal.
2. Check for poor carpet fit under the accelerator controls pedal.
3. Repair or replace as necessary and go to "VERIFICATION OF VEHICLE REPAIR " procedure. If OK, go to next step below.

■ Accelerator Pedal Voltage Inspection 

1. Connect APS connector.
2. IG "ON".
3. Check sensor data (Fig 1).

4. Data Analysis

   Condition		GDS Sensor Data
   		APS 1	APS 2
   G Key "ON" & Engine "OFF"	"Output voltages of APS 1 and APS 2 are in proportion to accelerating. APS 2 output voltage is half of APS 1 output voltage."
   	Release a pedal fully	0.58~0.93V	0.29~0.47V
   	Depress a pedal fully	3.85~4.35V	1.93~2.18V

5. Is data in accordance with "Data Analysis"?

   YES 

   • Check for poor connection between PCM and component: backed out terminal, improper mating, broken locks or poor terminal to wire connection. Repair as necessary and go to "VERIFICATION OF VEHICLE REPAIR " procedure.

   NO 

   • Substitute with a known-good component and check for proper operation. If the problem is corrected, replace component and then go to "VERIFICATION OF VEHICLE REPAIR " procedure.
