What are the error codes for fuel rail sensors?
Two common error codes relating to Fuel Rail Sensors on a CRD that may be logged are: P0193 – Fuel Rail Sensor circuit high input. The PCM has detected that the fuel pressure is not within the predetermined range. P0087 – Fuel Rail Pressure too low. Generally, a problem with the fuel delivery system that causes the pressure to be too low.
How does a fuel rail pressure sensor work?
The Fuel Rail Pressure (FRP) sensor is a diaphragm strain gauge device in which resistance changes with pressure. The electrical resistance of a strain gauge increases as pressure increases, and the resistance decreases as the pressure decreases.
What is the DTC code for fuel rail pressure?
DTC P0193 is defined as Fuel Rail Pressure Sensor High Input. What are the common causes of code P0193 ? Depending on year, make, and model, DTC P0193 may have number of causes.
How much does it cost to repair fuel rail sensor?
The auto repair labor rates vary widely across the country, and even within the same city. Most auto repairs shops charge between $75 and $150 per hour. The Fuel Rail Pressure (FRP) sensor is a diaphragm strain gauge device in which resistance changes with pressure.
What is the diagnostic code for fuel rail pressure sensor?
P0193 is a diagnostic trouble code (DTC) for “Fuel Rail Pressure Sensor Circuit High Input”. This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation.
How much does a fuel rail sensor cost?
Most auto repairs shops charge between $75 and $150 per hour. The Fuel Rail Pressure (FRP) sensor is a diaphragm strain gauge device in which resistance changes with pressure. The electrical resistance of a strain gauge increases as pressure increases, and the resistance decreases as the pressure decreases.
What does error code p0193 mean on fuel rail sensor?
Error Code P0193: Fuel Rail Pressure Sensor A Circuit High. Error Code P0193 is described as Fuel Rail Pressure Sensor Circuit High Input. Meaning, the PCM (powertrain control module, also known as ECM or engine control module) has determined that the fuel pressure is outside the predetermined range of the vehicle’s manufacturer.
How does the FRP sensor on the fuel rail work?
The FRP sensor measures the pressure difference between the fuel rail and atmospheric pressure. The FRP sensor nominal output varies between 0.5 and 4.5 volts, with 0.5 volts corresponding to 0 MPa (0 psi) gauge and 4.5 volts corresponding to 26 MPa (3771 psi) gauge.
