P0087 FUEL PUMP
DTC LogicINFOID:0000000001162564
DTC DETECTION LOGIC
NOTE:
Conditions for applying the diagnostic procedure to the stored DTCs:
The DTC becomes present during the first 30 seconds after the engine starts.
 In low ambient temperature conditions, diagnostic can.t make difference between a normal long engine start
and abnormal long engine start. So, DTC must be take in account only if customer complains about too long
or impossible engine start not only in cold conditions but also and especially in warm conditions. If customer
complains only in cold conditions, root cause of the problem could elsewhere like low battery level, bad fuel
specification (too viscous fuel). This DTC could appear after fuel filter too.
Special notes:
Starting and engine operation difficult or impossible.

P0190 FRP SENSOR
P0190 FRP SENSOR
DescriptionINFOID:0000000001162592
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. The ECM uses the signal from fuel rail pressure sensor as a feedback signal.
