P017B Nsu Ro Diagnostic Trouble Code
P017B Nsu Ro code definition:
P017B is a kind of OBD-II Diagnostic P-Powertrain Diagnostic Trouble Code for Nsu Ro.
P017B Nsu Ro is described as Fuel Rail Pressure Sensor Circuit Malfunction. This code is strictly about the incoming signal from the FRP (fuel rail pressure) sensor falling below the calibrated limit for a certain period of time. Other serious codes may cause this code to pop up, and they may come with dangerous drivability issues that may expose you to safety risks and cause damage to the engine in the long run.
Symptoms
Symptoms of a P017B Nsu Ro diagnostic trouble code may include:
- Possible spark knock (detonation / pre-ignition)
- Poor fuel economy
- The engine oil will exhibit dilution from the ECUs attempts to increase engine temperature. Some vehicles advance the fuel injection timing slightly after top center to afterburn a small amount of fuel to increase exhaust temperatures. Some of this fuel enters the crankcase. When the ECU determines the necessity to regenerate the DPF, the service life of the oil be shortened significantly
- The light may stay on or light intermittently as the DPF regenerates. The engine will be sluggish on acceleration.
|
Possible Causes :
- An air leak forward of the DPF will change the sensor readings resulting in the code
- Rusty exhaust systems, cracked exhaust manifolds or damaged or missing gaskets or donuts will cause air leaks.
- Defective ECU strategies or components will prevent proper regeneration

Common Misdiagnoses
- Exhaust Gas Recirculation System Valve 1 Problem
- BBV Sensor Circuit Low Voltage Problem
- Transmission Engaged At High Throttle Angle Problem
- Cruise Inhibit Control Circuit Problem
- TFP Valve Position Switch-Drive Without Drive Ratio Problem
Repair Processes :
If the scan tool has that capability, and the scan tool can operate the IMRC valves, then the problem is either resolved and a simple code clearing is all that's left or a new PCM would be called for.
Find out what kind of system you have and verify that voltage to the fuel level sensor is present at the fuel pump wiring harness.
Process Tips
Diagnostic trouble code P017B Nsu Ro is not difficult to diagnose and repair. Thus, it always pays to have a qualified technician to look after your vehicle should this error code arise.
Diagnosing this code requires the engine to be in good running shape, without unmetered air entering the engine. If other codes that relates to misfiring condition, lean running or air entering the engine is present, then you must first fix those error codes before P017B Nsu Ro.
Fortunately, P017B Nsu Ro is a fairly common OBD code, meaning that it applies to all makes and models of vehicles made after 1996.
