P0306 Engine Code Repair
Meaning of P0306 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 $240-$400 depending on the car, but that's usually the cost of parts because the labor is relatively simple.
P0306 Fault Symptoms :
- Check engine light comes on
- Engine stalling or misfiring
- Engine performance issues
- Car not starting
If one of these reasons for P0306 code is occuring now you should check P0306 repair processes.
Now don't ask yourself; What should you do with P0306 code ?
The solution is here :
P0306 Possible Solution:
Excessive air inflow can be caused by a vacuum leak, a dirty sensor or, an exhaust gas recirculation valve not closing properly. If the problem is not enough fuel, the culprit may be dirty injectors or fuel filters, a weak fuel pump or a leaky fuel pressure regulator. The lean fuel mix error may be accompanied by rough idling, engine misfires, hesitation during acceleration and overall poor engine performance.

Regarding the P0306 code, it would probably be worthwhile to carefully inspect the wire harness near the intake manifold bracket. This is done most easily from below the car in the area near the oil filter.
P0306 OBD-II Diagnostic Powertrain (P) Trouble Code DescriptionP0306 OBD-II Trouble Code When a misfire occurs, engine speed will fluctuate. If the engine speed fluctuates enough to cause the Crankshaft Position (CKP) sensor signal to vary, the Engine Control Module ( P0306 code.Main reason For P0306 CodeThe reason of P0306 OBD-II Engine Trouble Code is Manifold Absolute Pressure/Barometric Pressure Circuit High Input. |
P0306 DTCs may also be triggered by faults earlier down the line. For example, a dirty MAF sensor might be causing the car to overcompensate in its fuel-trim adjustments. As a result, oxygen sensors are likely to report fuel mixture problems.
