DTC P0652, P0653 SENSOR POWER SUPPLY

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.
Diagnostic ProcedureEBS011CR
1. CHECK GROUND CONNECTIONS
1. Turn ignition switch OFF.
2. Loosen and retighten ground screws on the body. Refer to EC-1055, "
Ground Inspection" .
OK or NG
OK >> GO TO 2.
NG >> Repair or replace ground connections.

Specification data are reference values.
On Board Diagnosis LogicEBS011DQ
NOTE:

If DTC P1272 is displayed with DTC P0652 or P0653, first perform trouble diagnosis for DTC P0652
or P0653. Refer to EC-1240, "
DTC P0652, P0653 SENSOR POWER SUPPLY" .
DTC Confirmation ProcedureEBS011DR
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. Start engine and keep engine speed more than 4,000 rpm for at
least 5 seconds, then release the accelerator pedal.
4. If 1st trip DTC is detected, go to EC-1266, "
Diagnostic Proce-
dure" .

DTC P1273 FUEL PUMP

DTC P1273 FUEL PUMPPFP:16700
DescriptionEBS011DU
To control the amount of the fuel inhalation of the fuel pump, a plunger is built into the fuel pump. When the
amount of the fuel inhalation of fuel pump increases, the fuel raises the fuel exhalation pressure. As a result,
the fuel injection pressure is raised. When the load of the engine increases, the ECM sends a signal to the fuel
pump to raise the injection pressure.
CONSULT-II Reference Value in Data Monitor ModeEBS011DV
Specification data are reference values.
On Board Diagnosis LogicEBS011DX
NOTE:

If DTC P1273 is displayed with DTC P0652 or P0653, first perform trouble diagnosis for DTC P0652

DTC Confirmation ProcedureEBS011DY
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. Start engine and warm it up to normal operating temperature.
2. Select “DATA MONITOR” mode with CONSULT-II.
3. Keep engine speed more than 2,000 rpm for at least 10 sec-
onds.
