z
Measure the voltage between the APP
sensor connector D or F terminal (wiring
harness side) and the APP sensor connector
C or G terminal (wiring harness side)
z
Is the voltage between 4-6 V?
No
Repair if necessary. Then go to Step 12.

INSPECT FUNCTIONALITY OF APP
CIRCUITS
z
Are APP1, APP2 or APP3 out of range?
NOTE:
z
Use the voltage measurements from
Step 4.
Yes Go to the next Step.
No
Go to Step 11.
7
INSPECT FUNCTIONALITY OF APP
SENSOR
z
Turn the ignition switch off.
z
Disconnect the APP sensor connector.
z
Measure the resistance between the
following APP sensor terminals (APP
sensor component side).
{
E and D or F: 600-1,370 ohms
{
E and C or G: 720-1,660 ohms
{
E and H: 1,300-2,960 ohms
{
E and B: 1,250-2,860 ohms
{
H and D or F: 750-1,720 ohms
{
H and C or G: 660-1,520 ohms
{
H and B: 1,230-2,810 ohms
{
B and D or F: 710-1,640 ohms
{
B and C or G: 580-1,340 ohms
{
D or F and C or G: 200-470 ohms
z
Are all the resistances within
specifications?
Yes Go to next Step.
No
Replace the accelerator pedal. Then go to
Step 12.
8
INSPECT APP SENSOR SIGNAL CIRCUIT
FOR OPEN CIRCUIT
z
Disconnect the PCM connector.
z
Inspect for continuity between the
following terminals:
{
P2121: APP sensor terminal E and
Yes Go to the next step.
