The EVAP system consists of many parts, including but not limited to the gas cap, fuel lines, carbon canister, purge valve, and other hoses.

Fuel vapors are routed by hoses to a charcoal canister for storage. Later, when the engine is running a purge control valve opens allowing intake vacuum to siphon the fuel vapors into the engine. EVAP emission canister purge is contolled by a valve which allows engine vacuum to pull stored fuel vapors from fuel tank into the engine to be burned, rather than be vented to atmosphere.

A vacuum switch is used to detect when flow exists. If the PCM commands purge and sees that the switch is closed indicating no detected purge flow P Toyota is set.

I had the same codes with check engine and TCS dash lights a couple of months ago on my 4runner. My private mechanic checked them out then and guessed that I must have not put the gas cap on tight. He cleared them and I've run fine until yesterday. They came back again. Autozone read the codes - and - so I just made a service appointment for next week. Meanwhile, I filled up with gas, checked the gas cap, and wanted to try clearing the codes to see if they come back or not.

Autozone in NJ will not clear them they say they aren't allowed to. Two knowledgeable people also told me not to disconnect the battery because some other engine computer will lose memory of the fuel mixture and the car will run rough. And one other person advised to pull the EFI fuse, but that is not listed on my fuse box panel. So, I'm stuck, tooP indicates that there is an issue with the Evaporative Emissions System.

Gasoline in your gas tank and entering the tank does evaporate a little causing gas fumes, which harm the environment. The evap system essentially collects them, and routes them through the engine to be burned. A pressure sensor in the fuel tank lets the ecm the van's computer watch all the associated pressure changes.

When things don't change the way they should, the computer sets a code, or four P, P, P, P which are about as useful as a sliding door on a submarine, since they do NOT really help you pin down which bit is leaking or failed at all. Now your van is an environmental hazard, won't pass a smog inspection, and all the neighbors will laugh about you.

The codes are telling us that this system has stopped working or the sensor in the tank thinks so anyway.The evaporative emission control EVAP system prevents fuel vapors from escaping into the atmosphere.

When the vent control valve opens, the fuel vapors from the fuel tank travel through a vent line to the charcoal canister. The fuel vapors are then absorbed and stored by activated charcoal pellets in the charcoal canister. On the charcoal canister is a purge valve. When the purge valve is opened, the vacuum from the engine draws the fuel vapors out of the charcoal and into the engine intake manifold where it is then used as part of the air-fuel mixture needed for combustion within the cylinders of the engine.

However, when check engine light code P is set, the purge valve is not properly regulating the flow of the fuel vapors by allowing too much flow or too little flow.

Code P does not pose any serious danger to the driver or the vehicle and there are no drivability issues that may occur. However as the case with all Check Engine Light codes, it should be fixed as soon as possible to prevent any further damage to your vehicle.
