P1151 Engine Trouble Code
Meaning of P1151 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.
P1151 Fault Symptoms :
If one of these reasons for P1151 code is occuring now you should check P1151 repair processes.
Now don't ask yourself; What should you do with P1151 code ?
The solution is here :
P1151 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.
P1151 Code Meaning :
|OBD-II Diagnostic Powertrain (P) Trouble Code For Engine||Fuel And Air Metering||Fuel Rail/System Pressure - Too High||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.
P1151 OBD-II Diagnostic Powertrain (P) Trouble Code DescriptionP1151 OBD-II Trouble Code Lack Of HO2S21 Switch - Sensor Indicates Lean is one of the definitions for the P1151; however your vehicles manufacturer may have a different definition for the P1151 code. Please check below for you P1151 code.
