What Does P0149 Mean? OBD-II Code Decreased engine performance is defined as a Fuel Timing Error The engine control module (PCM) uses a Fuel Rail Pressure Sensor to determine the amount of fuel going to the injectors. If the PCM does not see that the commanded pressure is equal to the actual pressure, the PCM will set code P0149. engine code P0149P0149 fixobd P0149dtc P0149obd code P0149obd2 P0149P0149 car codediagnostic code P0149car code P0149check engine code P0149fehlercode P0149P0149 fiatcodigo P0149codigo falla P0149P0149 kody b??dówcodigo de falla P0149 What are the common causes of P0149 ? Depending on year, make, and model, DTC P0149 may have number of causes. Here are some of the most common. Fuel Timing Solenoid – Failure of the solenoid is the most common problem experienced by drivers. It is usually held in by 2 or 3 bolts and sealed by a couple of o-rings. The part may be available separately from the fuel pump assembly, though it may require rewiring from the controller or ECM to the new solenoid. Mis-Timing – If crankshaft / fuel-pump correlation is off by even one tooth, this will cause fuel timing problems that the ECM cannot compensate for. What are the symptoms of P0149 ? Assuming that the vehicle will start, inconsistencies in fuel pump timing can result in engine damage. A stored code P0149 should be considered severe. Symptoms of a P0149 code may include: No start condition Diminished engine performance Additional fuel system codes Intense fuel odor The vehicle may enter imp-in mode Excessive smoke from exhaust How do you troubleshoot P0149 ? If all testing has passed so far yet you still have the same code, check your scan tool and see if it can open and close the IMRC valve. Look for missing ground strap or a rusty ground where the fuel tank is grounded to the frame. Check for damage to the wiring harness connector. Replace the oxygen sensor that is downstream from the catalytic converter on the side of the engine that does not contain cylinder #1. Also, if a oxygen sensor code stating "heater circuit malfunction" the sensor has most probably failed.
