STEP 4. Check connector C-58 at ECM <M/T> or connector 
C-55 at PCM <A/T> for damage.
Q: Is the connector in good condition?

YES : Go to Step 5.
NO :  Repair or replace it. Refer to GROUP 00E, Harness 

Connector Inspection 

P.00E-2

. Then go to Step 11.

STEP 5. Check for open circuit and short circuit to ground 
between throttle position sensor connector B-07 (terminal 
No. 4) and ECM connector C-58 (terminal No. 42) <M/T> or 
PCM connector C-55 (terminal No. 46) <A/T>.
Q: Is the harness wire in good condition?

YES : Replace the ECM or PCM. Then go to Step 11.
NO :  Repair it. Then go to Step 11.

STEP 6. Check the throttle position sensor.
(1) Disconnect the connector B-07.

(2) Measure the resistance between throttle position sensor 

side connector terminal No. 1 and No. 4.

Standard value: 3.5 

− 6.5 kΩ

(3) Measure resistance between the throttle position sensor 

side connector terminal No. 1 and No. 3.

(4) Move the throttle valve from the idle position to the full-open 

position.

• Resistance should change smoothly in proportion to the 

opening angle of the throttle valve.

Q: Is the resistance between 3.5 and 6.5 k

Ω?

YES : Go to Step 7.
NO :  Replace the throttle position sensor. Refer to 

P.13B-1117

, Throttle Body. Then go to Step 11.

STEP 7. Check connector C-58, C-62 at ECM <M/T> or 
connector C-55, C-59 at PCM <A/T> for damage.
Q: Is the connector in good condition?

YES : Go to Step 8.
NO :  Repair or replace it. Refer to GROUP 00E, Harness
