Specification data are reference values and are measured between each terminal and ground.
Pulse signal is measured by CONSULT-II.
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.

DTC P1275 FUEL PUMP
Diagnostic ProcedureEBS0124L
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 2.
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 1.
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-1471, "
Component Inspection" .
OK or NG
OK >> GO TO 4.
NG >> Replace fuel rail.
4. CHECK FUEL PUMP
Refer to EC-1623, "
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-1370, "
Fuel Pump Learning Value Clearing" .
>>INSPECTION END
6. CHECK INTERMITTENT INCIDENT
Refer to EC-1414, "
TROUBLE DIAGNOSIS FOR INTERMITTENT INCIDENT" .

DTC P2135 APP SENSOR
DTC P2135 APP SENSORPFP:18002
DescriptionEBS0124O
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 ModeEBS0124P
Specification data are reference values.
*: These signals are converted by ECM internally. Thus, these differ from ECM terminals voltage.
On Board Diagnosis LogicEBS0124R
The MI will not light up for this self-diagnosis.
NOTE:
If DTC P2135 is displayed with DTC P0642 or P0643, first perform trouble diagnosis for DTC P0642
or P0643. Refer to EC-1575, "
DTC P0642, P0643 SENSOR POWER SUPPLY" .
If DTC P2135 is displayed with DTC P0652 or P0653, first perform trouble diagnosis for DTC P0652
or P0653. Refer to EC-1579, "
DTC P0652, P0653 SENSOR POWER SUPPLY" .
DTC Confirmation ProcedureEBS0124S
NOTE:
If DTC Confirmation Procedure has been previously conducted, always turn ignition switch OFF and wait at
least 10 seconds before conducting the next test.
WITH CONSULT-II
1. Turn ignition switch ON.
2. Select “DATA MONITOR” mode with CONSULT-II.
3. Wait at least 5 seconds.
4. Depress accelerator pedal slowly spending 5 seconds, and then
release it slowly spending 5 seconds.
5. If DTC is detected, go to EC-1628, "
Diagnostic Procedure" .
