I have a error code 46 which is described as "right fuel metering." This same code was returned 17,000 miles ago, and the dealership replaced "a faulty speed sensor." I show that as code 17 but whatever. What do I do with error code 46? The guide says that this error has to do with "manifold absolute pressure sensor."

MAP sensor sets fuel and air mixture based on manifold vacuum. First check the vacuum line for leaks/cracks, if OK then replace the MAP sensor. Also spray an electronics cleaner on MAP connector.
