STEP 10. Check for harness damage between engine
coolant temperature sensor connector B-11 terminal 2 and
ECM connector C-60 terminal 92 <M/T> or PCM connector
C-54 terminal 57 <A/T>.
Q: Is the harness wire in good condition?

YES : Replace the ECM or PCM. Then go to Step 14.
NO : Repair it. Then go to Step 14.

STEP 11. Check the engine coolant temperature sensor.
(1) Disconnect the engine coolant temperature sensor

connector B-11

(2) Remove the engine coolant temperature sensor.
(3) With the temperature sensing portion of engine coolant

temperature sensor immersed in hot water, check
resistance.

Q: Is the resistance at the standard value?

YES : Go to Step 12.
NO : Replace the engine coolant temperature sensor. Then

go to Step 14.

STEP 12. Check connector C-60 at ECM <M/T> or
connector C-54 at PCM <A/T> for damage.
Q: Is the connector in good condition?

YES : Go to Step 13.
NO : Repair or replace it. Refer to GROUP 00E, Harness

Connector Inspection (

P.00E-2

). Then go to Step 14.

STEP 13. Check for harness damage between engine
coolant temperature sensor connector B-11 terminal 1 and
ECM connector C-60 terminal 83 <M/T> or PCM connector
C-54 terminal 44 <A/T>.
Q: Is the harness wire in good condition?

YES : Replace the ECM or PCM. Then go to Step 14.
NO : Repair it. Then go to Step 14.

STEP 14. Test the OBD-II drive cycle.
(1) Carry out a test drive with the drive cycle pattern. Refer to,

Procedure 6

−

Other Monitor (

P.13A-5

).

(2) Check the diagnostic trouble code (DTC).

Q: Is the DTC P0117 is output?

YES : Retry the troubleshooting.
NO : The inspection is complete.

DTC P0121: Throttle Position Circuit Range/Performance Problem

CIRCUIT OPERATION

•

A 5-volt power supply is applied on the TPS
power terminal (terminal 4) from the ECM
(terminal 81) <M/T> or PCM (terminal 46) <A/T>.
The ground terminal (terminal 1) is grounded with
ECM (terminal 92) <M/T> or PCM (terminal 57)
<A/T>.

•

When the throttle valve shaft is turned from the
idle position to the fully opened position, the
resistor between the TPS output terminal
(terminal 3) and ground terminal will increase
according to the rotation.
