Give us the Evap Code you got or Google
the code for a cause & solution

There are Vent Solenoids
Pressure Solenoids
Purge Valve
Canister
& more along with lots of hoses--need the codes
to start a diagnoses

Testimonial: "I WAS TOLD BY ONE SERVICEMAN THAT THE CODE INDICATED THE CANISTER AND IT WOULD NOT HURT TO DRIVE IT THAT WAY BUT IT WOULD PROBABLY COST 500 BUCKS TO FIX IT. SO WHAT DO I DO NOW. I DON'T HAVE 500 BUCKS TO FIX A STUPID BAD SENSOR."

To know what it exactly is, you need a code scanner hooked to it.
If there is an autozone near you, go there, tell them the engine light is on and you need the code, takes about 30 seconds. They don't charge, where other places do. Without that code you'll be replacing things you don't need to. There is other sensors in the emission system other than the 02 sensors.

I would send the car for a smoke test for the emissions leak...Find out where the leak is comming from..Repair it..Reset the codes, then do a drive cycle and see what happens...

Your sensor went off because it overknocked.
Try using a different type of fuel with a higher octane.
Erase the code and use the better gas. if it comes back then we will worry about replacing it.

What does code PO453 mean


the evaporative emission system (EVAP) control system pressure sensor has sent high voltage to the ecm or engine control module and triggered this code either the purge valve located under the car by the gas tank has gone bad, or the charcoal canister has become gas soaked and is pressurizing from gas fumes, or the sensor or wires have shorted , there is also a secondary valve located und the cover of the intake that should also be checked for shorts that can trigger this code but usually it is the one under the car that goes out 9 out of 10 times it is from fuel being burped into the evap canister or charcoal canister from the gas tank which is caused from overfilling the tank or mid day heat of 90 or better with a full tank

My 2001 saturn is trying to turn over and start but wont check engine light code p0452


P0452 Saturn Fuel Tank Pressure Sensor Circuit Low Voltage
"P0452 - Evaporative Emission Control System Pressure Sensor Low Input. Evaporative Emission Control System Pressure Sensor Low Input indicates a low voltage problem in the Fuel Tankicon1.png Pressure Sensor (FTPS). What the fuel FTP sensor does is convert fuel tank absolute pressure into electrical signals and inputs the signal to the ECM/PCM, (Computer).
First thing to do is make sure the gas cap is good and tightened properly. Then check the vacuumicon1.png lines and wiring at the FTPS (Location-Fuel Tank) to be sure they are good, clean and tight.
Barring a wiringicon1.png problem it can be a bad FTPS or PCM.
"
I copied this blog on the code p0452. So, check gas cap, check vacuum lines from fuel tank and trace the lines making sure there is no break. check wire plug on the fuel tank pressure sensor.

Gas cap light and check engine light on 2001 ford taurus ses


Sorry, but there is no "sensor at the fuel cap". Therefore, there is no code that says "sensor at the fuel cap". There is, however, a Diagnostic Test Code (DTC) That indicates a possible problem with the fuel cap.
(HINT: When you want information on codes, it is usually wise to include the code number that you are getting - that way, it can be looked up, instead of GUESSING at what the problem is from a code description that some generic code reader is telling you..)
DTC P0457 is defined by SAE J2012 as "Evaporative Emission System Leak Detected (fuel cap loose/off)"

At this point, I am ASSUMING this is the code you got.

This DTC is set when the Powertrain Control Module (PCM) detects that there is an in-tank pressure drop that is more than 7in. H2O within 30 seconds directly after refueling, or there is excessive purge (fuel Vapor) flow more than .06 lbs. per minute. Possible causes are:
> Fuel filler cap not installed after refueling
> Fuel filler cap loose or cross-threaded

There are other malfunctions that can also cause this code to set, but it will be accompanied by other codes indicating other possible failures.
If there are no other Evaporative Emissions System codes present, then there is most likely a problem with the way your fuel cap was put on the last time you got fuel.

Check your fuel cap and make sure it is on correctly and is tight.

My 2005 Jeep Liberty Limited only has 84000 miles and the check engine light came on. What does this code mean? The gas cap doesnt seem like it get very tight.


Hi Katherine:
P0456 - Evaporative Emissions System - Small leak detected
The Powertrain Control Module (PCM) at different times performs various tests on the EVAP system. OBD II Enhanced EVAP systems are in place to keep fuel tank vapors from venting into the atmosphere, and instead purges them into the engine to be burned. Regular pressure tests are conducted by the PCM to monitor the sealed system for leaks. The PCM monitors the EVAP system pressure by watching the fuel tank pressure (FTP) sensor. When the sensor indicates a small leak in the EVAP system, this code is set.

Potential Symptoms: there will likely be no noticeable symptoms other than the Malfunction Indicator Lamp (MIL). This is because the EVAP system is a closed system and only controls fuel tank vapors, not engine management.

Causes: Usually this P0456 code is caused by an incorrect or faulty gas cap. Filling the fuel tank with the engine running could conceivable cause this code as well or if the cap wasn't properly tightened. Any of the following could also be the cause:
A small leak in any of the EVAP hoses or fuel tank hoses
A small leak in the purge valve or vent valve
The EVAP Canister may be leaking

Possible Solutions: first, using a scan tool activate the vent solenoid, sealing the system. Then monitor the fuel tank pressure (FTP) sensor. If the system is sealing properly, the number will stay consistent. If is isn't, the pressure sensor will show that as well. If the system slowly leaks, use a smoke machine and watch for smoke exiting the system at any EVAP component. Any where there is smoke exiting the system, that is the faulty component. Do not pressurize the EVAP system with air pressure. Doing so can damage the purge and vent solenoids in the system.

Hope this helps; also keep in mind that your feedback is important and I will appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day.

Engine scan codes are P0442, P0456 , can you please help me with these codes


P0442 - Evaporative Emission Control System Leak Detected (small leak)
This indicates a fuel vapor leak in the EVAP control system. It means a very small leak has been detected. In fact, the leak can be from a hole as small as 0.04" in diameter. The (EVAP) emission control system prevents the escape of fuel vapors from a vehicle's fuel system. 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.

Symptoms: You likely won't notice any drivability problems.

Causes: A code P0442 most likely means one or more of the following has happened:
A loose or improperly affixed gas cap
A non-conforming gas cap (i.e. not factory/original brand)
A small leak/hole in a fuel vapor hose/tube
Other small leak in EVAP system
Faulty vent o-ring seal

Possible Solutions: With a P0442, the most common repair is to:
Remove and reinstall the gas cap, clear the codes, and drive for a day and see if the codes come back.
Otherwise, replace the gas cap, or
Inspect the EVAP system for cuts/holes in tubes/hoses

P0440 - Evaporative Emission (EVAP) System


evaporative emission (EVAP) system has a large leak.
Check the gas cap or vent valve. these are the most common problems.


The Powertrain Control Module (PCM) at different times performs various tests on the EVAP system. OBD II Enhanced EVAP systems are in place to keep fuel tank vapors from venting into the atmosphere, and instead purges them into the engine to be burned.

When the sensor indicates a small leak in the EVAP system, this code is set.


Here are some additional causes.

* A small leak in any of the EVAP hoses or fuel tank hoses
* A small leak in the purge valve or vent valve
* The EVAP Canister may be leaking

Code 455 with low fuel level indicator light flashing comes on in my mercedes e 420


you have a leak in the fuel evaporative emission system. The fuel light flashes when the gas tank and system is not sealed, and the purge control cant **** vacuum or hold vacuum in the tank. Usually its the gas cap not sealing the tank correctly, the "activated charcoal canister shut off valve" wont completely close the system, or the "purge control valve" under the hood isnt opening/pulsing correctly enough for the engine manifold vacuum to create the vacuum in the gas tank
