is it all the codes or just the p0087 that you are worried about?

 

my problem with P0087 and p062D
because system too lean code does not affect

 

P062D-
Possible CausesSetting Conditions

• Fuel injector for driver injector assembly has failed
• Engine room No. 2 fuse in Junction Block has failed
• ECM has failed

Engine cranking; system voltage more than 8.50v and the ECM did not detect any Bank 1 INJ1 or INJ2 signals for 10 engine revolutions. The D-4S system has two fuel injection methods. One is the in-cylinder direct injection method that directly injects pressurized fuel into the combustion chamber. The other is the intake port injection method. The ECM determines which fuel injection method to use in accordance with the engine conditions. For the in-cylinder direction injection method, the 2 injector drivers (EDU) in the engine room operate the fuel injectors (for direction injection) at high speeds.

P0087 Possible Causes

• Fuel pressure regulator has failed
• Fuel pump has failed
• Fuel pipe problem (high pressure side fuel pump injector)
• Fuel pipe problem (fuel tank - high pressure side fuel pump)
• Fuel pressure sensor has failed
• High pressure side fuel pump has failed
• Fuel injector has failed
• Fuel pressure sensor connector is damaged (check pins for damage, moisture)
• Fuel relief valve has failed
• ECM has failed

Engine running; then after the ECM commanded the High Pressure Fuel Pump to open the spill valve, the ECM detected the difference in the actual and target fuel pressure was less than -5 MPa. The cylinder fuel injection method high-pressure fuel system consists of the spill control valve, pump plunger and check valve. The spill control valve adjusts the discharge amount of the high-pressure fuel. The pump plunger operated by the camshaft, pressurizes fuel and the check valve mechanically opens and closes the line to the fuel delivery pipe. The fuel pump (high pressure) is located) in the Bank 1 cylinder head cover. It is driven by the cam located at the rear end of the intake camshaft. When the plunger moves up and down by the camshaft rotations, it pressurizes the fuel.
