B2051 Engine Trouble Code
Meaning of B2051 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.
B2051 Possible Solution:
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.
B2051 Code Meaning :
|OBD-II Diagnostic Body (B) Trouble Code For Engine||Fuel And Air Metering (Injector Circuit Malfunctions Only)||Ambient Air Temperature Sensor Circuit Low||Cylinder 1 Injector Circuit Low||Crankshaft Position Sensor A Circuit Low Input|
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.
B2051 OBD-II Diagnostic Body (B) Trouble Code DescriptionB2051 engine trouble code is about Crankshaft Position Sensor A Circuit Low Input.
Reason For B2051 CodeThe reason of B2051 OBD-II Engine Trouble Code is Ambient Air Temperature Sensor Circuit Low.
B2051 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.
