DTC P0192, P0193 FRP SENSOR

DTC P0192, P0193 FRP SENSORPFP:16638
DescriptionEBS011ZK
The fuel rail pressure (FRP) sensor is placed to the fuel rail. It measures the fuel pressure in the fuel rail. The
sensor sends voltage signal to the ECM. As the pressure increases, the voltage rises.
The ECM controls the fuel pressure in the fuel rail by the inlet throttling device. The ECM uses the signal from
fuel rail pressure sensor as a feedback signal.

The MI will not light up for these self-diagnoses.
NOTE:

If DTC P0192 or P0193 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" .

Overall Function CheckEBS01209
Use this procedure to check the overall function of the cooling fan. During this check, a DTC might not be con-
firmed.
WARNING:

Never remove the radiator cap when the engine is hot. Serious burns could be caused by high
pressure fluid escaping from the radiator.

Wrap a thick cloth around cap. Carefully remove the cap by turning it a quarter turn to allow built-
up pressure to escape. Then turn the cap all the way off.
WITH CONSULT-II
1. Check the coolant level in the reservoir tank and radiator.
Allow engine to cool before checking coolant level.
If the coolant level in the reservoir tank and/or radiator is below
the proper range, skip the following steps and go to EC-1484,
"Diagnostic Procedure" .
2. Confirm whether customer filled the coolant or not. If customer
filled the coolant, skip the following steps and go to EC-1484,
"Diagnostic Procedure" .
3. Turn ignition switch ON.
4. Perform “COOLING FAN” in “ACTIVE TEST” mode with CON-
SULT-II.
5. If the results are NG, go to EC-1484, "
Diagnostic Procedure" .
WITHOUT CONSULT-II
1. Check the coolant level in the reservoir tank and radiator.

2. Confirm whether customer filled the coolant or not. If customer
filled the coolant, skip the following steps and go to EC-1484,

3. Start engine.
Be careful not to overheat engine.
4. Set temperature control lever to full cold position.
5. Turn air conditioner switch ON.
6. Turn blower fan switch ON.
7. Run engine at idle for a few minutes with air conditioner operating.
Be careful not to overheat engine.

DTC P0628, P0629 FUEL PUMPPFP:16700
DescriptionEBS0122C
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 increases, the fuel pump 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.
