P0449 Engine Trouble Code

Meaning of P0449 engine trouble code is a kind of powertrain trouble code and theoretically you can drive for a few weeks or even months with a broken MAF sensor. You will notice a decrease in gas mileage and over time the car will eventually start stalling a lot. At a shop, the replacement cost is between $200-$300 depending on the car, but that's usually the cost of parts because the labor is relatively simple.

P0449 Fault Symptoms :

  1. Check engine light comes on
  2. Engine stalling or misfiring
  3. Engine performance issues
  4. Car not starting
If one of these reasons for P0449 code is occuring now you should check P0449 repair processes.
Now don't ask yourself; What should you do with P0449 code ?
The solution is here :

P0449 Possible Solution:

P0449 Engine

Gasoline engines use spark plugs to cause an explosion of fuel within the cylinder. In a properly timed engine, this explosion occurs at the proper moment to send the piston to the bottom of the cylinder and provide power to the drive shaft. If the plug wires are out of sequence, the explosion occurs at the wrong time. The improper timing of the explosion sometimes pushes the cylinder the wrong direction or interferes with the turning of the crank. As a result, the engine stutters or backfires, if it runs at all.

P0449 Code Meaning :

OBD-II Diagnostic Powertrain (P) Trouble Code For Engine Intake Valve Control Solenoid Circuit Low O2 Sensor Heater Circuit Malfunction Injection lump Fuel Metering Control 'B' High (Cam/Rotor/Injector) Reverse Input Circuit

The poor running symptoms are consistent with a MAP sensor malfunction. In addition, in some cases, a bad MAP sensor will not throw a code. Again, the ELD code likely represents a separate wiring issue.

P0449 OBD-II Diagnostic Powertrain (P) Trouble Code Description

P0449 OBD-II Trouble Code The Evaporative Emission System (EVAP) canister vent control valve is located on the EVAP canister and is used to seal the canister vent. This solenoid (the EVAP canister vent control valve) responds P0449 code.

Main reason For P0449 Code

The reason of P0449 OBD-II Engine Trouble Code is O2 Sensor Heater Circuit Malfunction.

P0449 DTC reports a sensor fault, replacement of the sensor is unlikely to resolve the underlying problem. The fault is most likely to be caused by the systems that the sensor is monitoring, but might even be caused by the wiring to the sensor itself.
