P0647 Engine Trouble Code

Meaning of P0647 engine trouble code is : 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.

P0647 Possible Solution:

P0647 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.

P0647 Code Meaning :

P 0 6 4 7
OBD-II Diagnostic Powertrain (P) Trouble Code For Engine Intake Valve Control Solenoid Circuit Low Fuel Temperature Sensor B Circuit Range/Performance Injection lump Fuel Metering Control 'B' High (Cam/Rotor/Injector) Shift/Timing Solenoid Malfunction/ 3-2 Shift Solenoid Circuit Electrical

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.

P0647 OBD-II Diagnostic Powertrain (P) Trouble Code Description

P0647 OBD-II Trouble Code A/C clutch relay may also be referred to as A/C compressor clutch relay. A/C clutch relay circuit is monitored when ignition is on and battery voltage is greater than 10.4 volts. P0647 code.

Reason For P0647 Code

The reason of P0647 OBD-II Engine Trouble Code is Fuel Temperature Sensor B Circuit Range/Performance.

P0647 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.
