DTC P0123 THROTTLE/PEDAL POSITION SENSOR/SWITCH "A" CIRCUIT
HIGH INPUT
COMPONENT LOCATION
E34BDD3C
Refer to DTC P0122.
GENERAL DESCRIPTION
EC220AC2
Refer to DTC P0122.
DTC DESCRIPTION
ED5835FD
Checking output signals from TPS1 every 8.5 sec. under detecting condition, if an output signal is above 4.75V for more
than 0.1 sec., PCM sets P0123. MIL(Malfunction Indication Lamp) turns on when the malfunction lasts till consecutive 2
driving cycle.

SIGNAL CIRCUIT INSPECTION
E3E9DEDF
1.
Check voltgae
1)
IG "OFF" and disconnect TPS connector.
2)
IG "ON" and ENG "OFF"
3)
Measure voltage between terminal 2 of TPS harness connector and chassis ground.
Specification : Approx. 5V
4)
Is the measured voltage within specification?
YES
▶ Go to "Check short to battery in harness" as follows.
NO
▶ Go to "Check open in harness" as follows.
2.
Check open in harness
1)
IG "OFF" and disconnect TPS connector and PCM connector.
2)
Measure resistance between terminal 2 of TPS harness connector and terminal C30-B (48) of PCM harness
connector.
Specification : Below 1Ω
3)
Is the measured resistance within specification?
YES
▶ Go to "Ground Circuit Inspection" procedure.
NO
▶ Repair open in harness, and go to "Verification of Vehicle Repair" procedure.
3.
Check short to battery in harness
1)
IG "OFF" and disconnect TPS connector and PCM connector.
2)
Measure resistance between terminals 4 and 2 of TPS harness connector.
3)
Measure resistance between terminals 7 and 2 of TPS harness connector.
4)
Measure resistance between terminals 5 and 2 of TPS harness connector.
5)
Measure resistance between terminals 8 and 2 of TPS harness connector.
Specification : Infinite
6)
Is the measured resistance within specification?
YES

FUEL SYSTEM
▶ Go to "Ground circuit inspection " procedure.
NO
▶ Repair short to battery in harness, and go to "Verification of Vehicle Repair" procedure.
GROUND CIRCUIT INSPECTION
E0E47490
1.
IG "OFF" and disconnect TPS connector.
2.
IG "ON" and ENG "OFF"
3.
Measure voltage between terminal 4 of TPS harness connector and chassis ground.
4.
Measure voltage between terminals 4 and 1 of TPS harness connector.
Specification : Voltage difference between measurement "A" and "B" is below 200mV.
5.
Is the measured voltage within specification?
YES
▶ Go to "Component inspection" procedure.
NO
▶ Repair open or contact resistance in harness, and go to "Verification of Vehicle Repair" procedure.

3)
Is the measured resistance within specification?
YES
▶ Substitute with a known - good PCM and check for proper operation. If the problem is corrected, replace PCM
and go to "Verification of Vehicle Repair" procedure.
DTC TROUBLESHOOTING PROCEDURES
FLA -237
NO
▶ Substitute with a known - good ECT motor & TPS and check for proper operation. If the problem is corrected,
replace ECT motor & TPS and go to "Verification of Vehicle Repair" procedure.
CAUTION
Procedure of ETS Initialization
1.
Erase the trouble codes on PCM
2.
Turn the ignition key off and keep this condition until the main relay is turned off.(It will takes 10sec.)
3.
Turn ignition key on more than 1second to record the throttle motor position on the EEPROM
