Possible triggers for the OBD P0171 Pontiac code
Code P0171 Pontiac could mean that one or more of the following have occurred: The MAF (Mass Air Flow) sensor is flawed or faulty. Note: The use of “oil” filters can cause MAF to be contaminated if the filter is filled with oil. There is also a problem with some vehicles as MAF sensors produce silicone components that are used to protect passengers. There may be an outflow of water at the end of the MAF sensor.
The possible answers are as follows: In most cases, just cleaning up the MAF device is tricky. Refer to your workbook where it is if you need help. I find it best to get rid of them and clean them with an electric cleaner or brake cleaner. Make sure you are careful not to damage the MAF sensor, and make sure it is dry before resetting? Monitor all vacuums and PCVs, instead if necessary?
