Diagnostic Procedure
EBS013GT
1.
CHECK ECM OUTPUT SIGNAL CIRCUIT FOR OPEN AND SHORT
1.
Turn ignition switch OFF.
2.
Disconnect ECM harness connector and fuel pump harness
connectors.
3.
Check harness continuity between ECM terminal 10 and fuel
pump terminal 1.
Refer to Wiring Diagram.
4.
Also check harness for short to ground and short to power.
OK or NG
OK
>> GO TO 2.
NG
>> Repair open circuit or short to ground or short to power
in harness or connectors.
2.
CHECK FUEL PUMP GROUND CIRCUIT FOR OPEN AND SHORT
1.
Check harness continuity between ECM terminal 29 and fuel pump terminal 2.
Refer to Wiring Diagram.
2.
Also check harness for short to ground and short to power.
OK or NG
OK
>> GO TO 3.
NG
>> Repair open circuit or short to ground or short to power in harness or connectors.
3.
CHECK FUEL RAIL PRESSURE SENSOR
Refer to
EC-1063, "Component Inspection"
.
OK or NG
OK
>> GO TO 4.
NG
>> Replace fuel rail.
4.
CHECK FUEL PUMP
Refer to
EC-1208, "Component Inspection"
.
OK or NG
OK
>> GO TO 6.
NG
>> GO TO 5.
5.
REPLACE FUEL PUMP
1.
Replace fuel pump.
2.
Perform Fuel Pump Learning Valve Clearing. Refer to
EC-956, "Fuel Pump Learning Value Clearing"
.
>> INSPECTION END

DTC P2135 APP SENSOR
PFP:18002
Description
EBS013GW
The accelerator pedal position sensor is installed on the upper end
of the accelerator pedal assembly. The sensors detect the accelera-
tor pedal position and sends a signal to the ECM. The ECM uses the
signal to determine the amount of fuel to be injected.
CONSULT-II Reference Value in Data Monitor Mode
EBS013GX
Specification data are reference values.
*: This signal is converted by ECM internally. Thus, it differs from ECM terminal voltage.
ECM Terminals and Reference Value
EBS013GY
Specification data are reference values and are measured between each terminal and ground.
CAUTION:
Do not use ECM ground terminals when measuring input/output voltage. Doing so may result in dam-
age to the ECM's transistor. Use a ground other than ECM terminals, such as the ground.
