FUEL SYSTEM
5.
Is the measured voltage within specification?
YES
▶ Go to "Component Inspection" procedure.
NO
▶ Repair open or contact resistance inharness, and go to "Verification of Vehicle Repair: procedure.
COMPONENT INSPECTION
E2BE8CB7
1.
Check TPS
1)
IG "OFF" and disconnect TPS connector.
2)
Measure resistance between terminals 7 and 6 of TPS connector.(Component side)
Specification : 2.7 ~ 4.1kΩ
1. TPS1 ground
2. TPS1 signal
3. TPS2 signal
4. TPS 1 Reference Voltage (+5V)

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.
NO
▶ Substitute with a known - good TPS and check for proper operation. If the problem is corrected, replace TPS
and go to "Verification of Vehicle Repair" procedure.
NOTE
There is a memory reset function on scantool that can erase optional parts automatically detected and memorized
by PCM. After testing PCM on the vehicle, use this function to reuse the PCM on the others
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

FUEL SYSTEM
DTC P0230 FUEL PUMP PRIMARY CIRCUIT
COMPONENT LOCATION
ECC8A902
Main Relay
Fuel Pump Relay
SCMF16254L
GENERAL DESCRIPTION
E6E9EF13
The ECM provides ground to one side of the coil in the fuel pump relay to control the fuel pump relay. The other side of the
fuel pump relay coil is connected to fuel pump relay, which activates when the ignition switch is ON. The ECM monitors
the control circuit between the fuel pump relay and the ECM. When the ignition switch is turned ON, the ECM energizes
the fuel pump relay, which sends power to the fuel pump.
DTC DESCRIPTION
E614D1F8
Checking fuel pump relay circuit continuously under detecting condition, if open or short in the circuit is detected, PCM
sets P0230.In addition, Take note that open circuit in Main Relay may cause this P0230 code.
※ In addition, Take note that open circuit in Main Relay may cause this P0230 code.
