B013B Mitsubishi Eclipse Iii Diagnostic Trouble Code

B013B Mitsubishi Eclipse Iii code definition:
B013B is a kind of OBD-II Diagnostic B-Body Diagnostic Trouble Code for Mitsubishi Eclipse Iii.

B013B Mitsubishi Eclipse Iii 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. The spark should have a light tan color. If the sensor probe comes with white and chalky parts, this means it has been lagging between switching phases, and should be replaced.

Symptoms

Symptoms of a B013B Mitsubishi Eclipse Iii diagnostic trouble code may include:
  • Poor fuel economy
  • Possible spark knock (detonation / pre-ignition)
  • Misfire
  • The light may stay on or light intermittently as the DPF regenerates. The engine will be sluggish on acceleration.
Place of B013B in engine

Possible Causes :

  • Low fuel pressure caused by a clogged filter, failing fuel pump, failed fuel pressure regulator or clogged or leaking injectors.
  • Low fuel pressure caused by a clogged filter, failing fuel pump, failed fuel pressure regulator or clogged or leaking injectors.
  • A large vacuum leak would cause a massive amount of un-metered air to enter the intake manifold resulting in an overly lean mixture.

Common Misdiagnoses

  1. Control Module Throttle Actuator Position Performance Problem
  2. Air Conditioning (A/C) Clutch Feedback Circuit High Voltage Problem
  3. Cruise Vehicle Speed/Set Speed Difference Too High Problem
  4. Kick-Down Switch Failed Short Problem
  5. Park/Neutral Postion (PNP) Switch Circuit Engine Torque Signal Circuit Problem

Repair Processes :

Look for damage to the tank indicating impact that may have damaged the fuel pump or sender. Use the DVOM to test resistance and continuity on all system circuits if actuator and sensor resistance levels are in compliance with manufacturer's specifications.

Process Tips

Diagnostic trouble code B013B Mitsubishi Eclipse Iii 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 B013B Mitsubishi Eclipse Iii.

Fortunately, B013B Mitsubishi Eclipse Iii is a fairly common OBD code, meaning that it applies to all makes and models of vehicles made after 1996.
