Are you currently faced with a vehicle that exhibits an aggravating check engine light, and a p fault code that has left you in a state of confusion? Fortunately, the diagnosis and repair of many of the most common causes of a p fault code are relatively simple and can be handled by most avid DIY at home mechanics. Each of an engine's two halves is designated with a bank number, when speaking of v-configuration engines. This allows you to narrow down the portion of the engine where your problem has arisen, based on a given code. Therefore, in the case of trouble code p, bank 1 is displaying the characteristics of running too lean. Several factors can contribute to a p trouble code being set. Any issue, mechanically or electronically, that can cause stifled fuel delivery or unmetered air intake can lead to a lean condition. Some of the most common mechanical causes of a p error code are dirty or clogged fuel injectors, restricted fuel delivery supply or low fuel pressure, leaking vacuum lines or PCV hoses, cracked intake ductwork, and leaking intake gaskets. The most common of all p electrical-based faults are dirty or damaged MAF mass airflow sensors.

If it needs to be corrected more than that, the P code will be stored. If the air fuel mixture is slightly lean, you will often get no other symptoms from the P code other than the check engine light on your dashboard.
