What are the symptoms of a p2191 engine code?
Troubleshooting steps may vary depending upon manufacturer, type of fuel system, type of mass airflow sensor (MAF) and wire colors and type of air/fuel ratio sensor/oxygen sensor (AFR/O2) and wire colors. Symptoms of a P2191 engine code may include: Potential causes for this code to set are: Faulty air/fuel ratio sensor/oxygen sensor (AFR/O2)
Can a vacuum leak cause a misfire code?
It will also often result in misfire trouble codes, like the P0300 trouble code. When your car is misfiring on one specific engine, it is usually caused by a vacuum leak around the intake manifold gasket. If you have misfires on all cylinders, it can be a vacuum leak anywhere around the intake manifold.
What causes a vacuum leak on a DTC p2191?
Depending on year, make, and model, DTC P2191 may have number of causes. Here are some of the most common. Vacuum leaks are the most common problem we have encountered. Loose or broken vacuum hoses and intake leaks are common. Plastic intake gaskets on certain vehicles have been known to crack, leading to vacuum leaks.
What to do if your fuel pump code is p0174?
Here are some possible solutions to correct error code P0174: Inspect and fix the vacuum leaks Check the mass airflow sensor and have it replaced or serviced Replace the fuel pump Check the dirty fuel filter Replace a faulty oxygen sensor Inspect and replace PCV valve

What to do if your engine has a p0171 code?
Now, if the above oxygen (O2) sensor test confirms that they are OK, now you can confidently conclude that the engine has a vacuum leak and that this vacuum leak is the one causing the P0171 and/or P0174 diagnostic trouble code (s). Suggested Test 1: With the engine cold, visually and physically check all vacuum hoses.
