    check your fuel cap o-ring seal. It is a black rubber looking seal that seals between the threaded portion of the cap and the top of the gas tank fill inlet. If the seal is cracked or missing, the tank won't pressurize properly (it will leak air through the bad seal) and your check engine light will come on. If the seal looks okay, make sure you are tightening the fuel cap properly after filling with gas. It should be tightened until you hear at least 3 "clicks". This ensures the o-ring seal is compressed enough to seal properly. You can probably drive your vehicle for some time in this condition but you will not be able to pass an emissions test unless you have the code erased. It usually takes two driving trips (at least) to reset the code so if you erase the code and have it immediately tested, you might just pass.

The dealer will be the only one with the ability to scan it properly. it is an enviromental issue, and is checked when you go to renew you plate sticker, at an e-test. so if you don't need an e-test anytime soon, it won't effect the running of the car.but it will have to be fixed befor your next e-test

I have a 2004 Jeep Wrangler. The Engine light came on. I had Auto Zone check the code for me. I don't remember the number, but they said that it was the Purge Valve. I had to buy the Purge Valve from...


Could be the P0445 - Evaporative Emission Control System Purge Control Valve Circuit Shorted
The EVAP canister purge volume control solenoid valve uses a ON/OFF duty to control the flow rate of fuel vapor from the EVAP canister. The EVAP canister purge volume control solenoid valve is moved by ON/OFF pulses from the ECM. The longer the ON pulse, the greater the amount of fuel vapor that will flow through the valve.

Symptoms
- Engine Light ON (or Service Engine Soon Warning Light)

Possible causes
- Damage harness or connectors to the Purge Control Valve
- The valve circuit is open or shorted
- EVAP canister purge volume control solenoid valve may be faulty

When is the code detected?
- An excessively high voltage signal is sent to ECM through the valve

Try to remember this code number for additional details. Hope this helps, keep us updated.

On my 2001 rodeo the check engine lite came on and the only code that came up is po440, can you tell me what this is


This alarm concerns the function of the EVAP SYSTEM. This system monitors vacuum correctness. If a sufficient vacuum level cannot be achieved, a large leak or a faulty EVAP canister purge solenoid is indicated. It can be caused for the following reasons:
1) Disconnected or faulty fuel tank pressure sensor
2) Missing or faulty fuel cap
3) Disconnected, damaged, pinched, or blocked EVAP purge line.
4) Disconnected or damaged EVAP vent hose.
5) Disconnected, damaged, pinched, or blocked fuel tank vapor line.
6) Disconnected or faulty EVAP canister purge solenoid.
7) Disconnected or faulty EVAP canister vent solenoid.
8) Damaged EVAP canister.
9) Leaking fuel sender O-ring.
10) Leaking fuel tank or fuel filler neck.

My engine light is on . I have a code # E-0455


The PCM monitors vacuum level via the fuel tank pressure sensor input. At an appropriate time, the EVAP purge solenoid and the EVAP vent solenoid are turned on, allowing engine vacuum to draw a small vacuum on the entire evaporative emission system. After the desired vacuum level has been achieved, the EVAP purge solenoid is turned off, sealing the system. A leak is detected by monitoring for a decrease in vacuum level over a given time period, all other variables remaining constant. A large leak in the system causes DTC P0445 to be set.

If the desired vacuum level cannot be achieved in the test described above, a large leak or a faulty EVAP purge solenoid is indicated. This can be caused by the following conditions:

*Disconnected or faulty fuel tank pressure sensor.

*Missing or faulty fuel cap.

*Disconnected, damaged, pinched, or blocked EVAP purge line.

*Disconnected or damaged EVAP vent hose.

*Disconnected, damaged, pinched, or blocked fuel tank vapor line.

*Disconnected or faulty EVAP canister solenoid.

*Disconnected or faulty EVAP vent solenoid.

*Open ignition feed circuit to the EVAP vent or purge solenoid.

*Damaged EVAP canister.

I have a 1997 Toyota 4Runner and the Malfunction Indicator Lamp came on today. I took it to Auto Zone for a free diagnostic test and it came back as P0441...Definition: Evaporative emission control system...


The cause of this problem is a faulty gas cap. It is not making a proper seal. Change the cap & reset light with ob11 code reader. There may possibly be a leak elsewhere but this is usually the case. Good luck!
