Thank you. Torrent P Code Symptoms The P code on a Pontiac Torrent will often be thrown if the fuel injection system is not operating properly. Here are the typical symptoms that something is wrong when you have code P Mileage- may or may not suffer depending on how much the air fuel mixture has changed.

Misfire — If the air fuel mixture has gotten too far from factory specs, this can cause the Torrent to misfire. This youtube video is a great resource for diagnosing the P trouble code in your Torrent. Vacuum Leaks — With the Pontiac Torrent, one of the most common cause for the P code to show is a vacuum leak. Vacuum leaks particularly at the intake manifold and the MAF sensor are the most common culprits.

With most vehicles, the most common cause for the P or P code to show is a vacuum leak. Take a look around and see if you can find the vacuum leak. If the engine is letting in unmetered air, the intake manifold leaking is a very high likelihood.

But, the leak can be anywhere. A good scan tool can help you determine if there is a vacuum leak as well. Fuel trim at idle will be greatly affected by a vacuum leak. But, as you rev the engine, the fuel trim should dip down to around 0 give or take a few points. The mass air flow sensor calculates the volume of air entering the engine. It will have a wiring harness plugged into it. The number one culprit when it comes to the MAF sensor going bad is dirty air. This typically happens when the air filter has a bad seal.

Another way they can stop working properly is if they get dirty from fuel vapor. Either way, the mover here is to clean it with a MAF sensor cleaner. The EGR system is designed to recycle exhaust gasses for cleaner emissions.
