The first and last code are your start and stop so you can ignore them the P1130 and P1150 are your two front oxygen sensors( pre cats ) bank one and two. Depending on your millage it sounds like it is time for a little maintence. Normally they should be changed at or around 60,000 kms

You can disconnect your battery for a short period of time, 5-10 minutes should do it. There is no guarantee that the check engine light will not come back on in time, but it will make it go away at least temporarily.If you go to Autozone, 99% of the time they will hook up a code reader and diagnose your problem. It may be a minor and/or inexpensive fix. Please vote appropriately and leave feedback. I hope this helps and good luck.

Your 306 code means you have a misfire on cylender 6. That may be the cause of the po 125. Inspecdt the coil, spark plug wire, and spark plug on cylender 6. With the age of the car I would replace all 3 items. If you want know how to test all 3 I can tell you process of elimination is the way to do it. Do you know how to find cylender 6

P1457 HONDA - Evaporative Emissions Control System Leakage EVAP Canister Systemxicon.jpghttp://engine-codes.com/p1457_honda.htmlForum CodePossible causes- Missing Fuel cap
- Incorrect fuel filler cap used
- Fuel filler cap remains open or fails to close
- Foreign matter caught in fuel filler cap There is a Honda factory service bulletin with information on how to diagnose the P1456 on the following Honda models:
1998 Honda Accord
1999 Honda Accord
2000 Honda Accord
1998-2000 Honda Accord
symptoms- Engine Light ON (or Service Engine Soon Warning Light)
- Possible a noticeable fuel odor caused by the release of fuel vaporsP1457 HONDA Description The evaporative emission (EVAP) control system stores fuel vapor from the fuel tank in the EVAP canister temporarily to prevent it from escaping to the atmosphere and to enable it to be drawn into the engine by intake manifold vacuum and burned. In addition, the onboard refueling vapor recovery system (ORVR) stores fuel vapor generated when refueling in the EVAP canister.

The EVAP control system leak detection method improves the accuracy and frequency of the detection by determining faulty components and vapor leakage for each part. The EVAP control system (from the purge valve to the fuel tank) is divided into two parts. One is the "EVAP Canister Side" (from the EVAP two way valve to the purge valve) and the other is the "Tank Side" (from the EVAP two way valve to the fuel tank). There is 0.04 inch leak detection and 0.02 inch leak detection. If the 0.04 inch leak detection results are OK, the 0.02 inch leak detection runs. The P1457 code is detected when the EVAP system has a very small leak.

P0107 HONDA Description The Manifold Absolute Pressure sensor provides instantaneous manifold pressure information to the engine's Engine Control Module. The data is used to calculate air density and determine the engine's air mass flow rate, which in turn determines the required fuel metering for optimum combustion. A fuel-injected engine may alternately use a Mass Air Flow sensor to detect the intake airflow. A typical configuration employs one or the other, but seldom both.


In some vehicles the absolute pressure sensor is built into ECM.

2002 Hyundai XG350 Error Codes P1191, p1193 & P0446


Error codes P1191/P1193 are a paired code indicating the Electronic Throttle Sensor (ETS) had detected engine RPM's of less than 470, resulting in a potential "limp home" mode. Technical Service Bulletin #06-36-003 identified several differing possible causes, ranging from a faulty ETS -to- loose connectors -to- carbon buildup around the throttle body. Error codes P300/P302/P304 are misfire in cylinders 2 and 3. Have your fuel injection system cleaned out with a machine and replace your spark plugs. Error code P0455 indicates a large fuel vapor leak. This code can be caused by the following things:An actual fuel vapor leak, either through a hose or other damaged vapor system component, or via a loose, incorrectly installed, or missing fuel cap. A stuck closed purge control valve, which, during the self-test, will produce fuel tank pressure readings exactly the same as a vapor leak. A close valve that does not seal properly, allowing air to be sucked into the fuel vapor system during the self-test. Blockage in the line to the fuel tank pressure sensor, causing it to not see variations in tank pressure.


That is taken from Michael on fixya. I google the codes and that came up..

Check engine light came on went to auto zone said it was gas cap. Bought new gas cap. reset engine light. two days later check engine light is back on. what next?


Hi, if the code was P0455, there are other possible reasons. The computer fuel tank pressure sensor has detected a leak which could also be in the vapor canister, or the hose from the canister to the purge valve, or the purge valve itself may be leaking. Please inspect the system for these leaks. I may be able to provide some pics of these parts if you tell me your model, year, and engine info.

Evaporative Emission Control System Leak Detected (no purge flow or large leak)
What does that mean? This indicates a fuel vapor leak or lack of purge flow in the EVAP control system. It means a large leak has been detected. 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 p0455 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)
  • Other leak or damaged piece in EVAP system
Possible Solutions With a p0455, 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, and/or
  • Inspect the EVAP system for cuts/holes in tubes/hoses (you may hear a vacuum noise or smell fuel), repair if necessary

What is evaporation control system malfuction mean? The code is P0440


Hi, the computer has sensed through the fuel tank pressure sensor that the vapor cannister is not evacuating properly. I have pasted details on the EVAP system below. Check the purge valve on top of the engine as shown below (#1 in picture). Make sure the electrical connector is on the valve, that the wires are not damaged, and check the hose for kinks. If all looks good, I recommend you replace the valve. A new valve is $23 at autozone. Please let me know if you have more questions and thanks for using FixYa.

Description & Operation
EVAP Canister
The canister is filled with carbon pellets used to absorb and store fuel vapors. Fuel vapor is stored in the canister until the control module determines that the vapor can be consumed in the normal combustion process.
EVAP Control System
The evaporative emission (EVAP) control system limits fuel vapors from escaping into the atmosphere. Fuel tank vapors are allowed to move from the fuel tank, due to pressure in the tank, through the vapor pipe, into the EVAP canister. Carbon in the canister absorbs and stores the fuel vapors. Excess pressure is vented through the vent line and EVAP vent solenoid to atmosphere.
The EVAP canister stores the fuel vapors until the engine is able to use them. At an appropriate time, the control module will command the EVAP purge solenoid ON, open, allowing engine vacuum to be applied to the EVAP canister. With the EVAP vent solenoid OFF, open, fresh air will be drawn through the solenoid and vent line to the EVAP canister. Fresh air is drawn through the canister, pulling fuel vapors from the carbon.
The air/fuel vapor mixture continues through the EVAP purge pipe and EVAP purge solenoid into the intake manifold to be consumed during normal combustion. The control module uses several tests to determine if the EVAP system is leaking.
The EVAP system consists of the following components:
EVAP Purge Solenoid
The EVAP purge solenoid controls the flow of vapors from the EVAP system to the intake manifold. This normally closed solenoid is pulse width modulated (PWM) by the control module to precisely control the flow of fuel vapor to the engine. The solenoid will also be opened during some portions of the EVAP testing, allowing engine vacuum to enter the EVAP system.
EVAP Service Port
The EVAP service port is located in the EVAP purge pipe between the EVAP purge solenoid and the EVAP canister. The service port is identified by a green colored cap.
EVAP Vent Solenoid
The EVAP vent solenoid controls fresh airflow into the EVAP canister. The solenoid is normally open. The control module will command the solenoid closed during some EVAP tests, allowing the system to be tested for leaks.
Fuel Tank Pressure Sensor
The FTP sensor measures the difference between the pressure or vacuum in the fuel tank and outside air pressure. The control module provides a 5-volt reference and a ground to the FTP sensor. The FTP sensor provides a signal voltage back to the control module that can vary between 0.1-4.9 volts. As FTP increases, FTP sensor voltage decreases, high pressure = low voltage. As FTP decreases, FTP voltage increases, low pressure or vacuum = high voltage.

Strong fuel odor coming from left front fender by air filter ,also a lot of pressure build up in tank when you remove cap kmkaren56.@bellsouth.net


If the check engine light is on, take the car to an autoparts store and have them use a scan tool to retrieve any fault codes stored in the computer. Most autopart stores offer this service at no charge. There could be a problem with the evaportative emission control system. There is a charcoal cannister that stores gas vapors and when conditions are right, a purge valve opens and the vapors are used in the combustion process. The cannister can get full of vapors and if the valve/solenoid is bad, it cannot purge itself of the vapors. Also integral to the system is the gas cap. A faulty gas cap can cause problems within this system. I am not saying that the evap system is the cause, but the pressure build up in the tank makes me suspicious. Get the codes read and it will help narrow things down for you. Sure hope this helped and best wishes.

Check engine light code PO442


You likely won't notice any drivability problems. P0442 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.

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.

Good luck and hope this helps

  • Charcoal canister is clogged, loaded with fuel or with moisture
  • Fuel filler cap missing, loose (not tightened) or the wrong part
  • Fuel tank over-fill check valve cracked or damaged
  • Fuel tank seal leaking, fuel tank cracked or damaged/leaking
  • Fuel vapor hoses/tubes blocked or restricted, or fuel vapor control valve tube or fuel vapor vent valve assembly blocked
  • Vacuum hose or tubing cracked, damaged or disconnected
  • Vapor Pressure sensor incorrectly installed
  • PCM has failed
onepx.gif Engine started cold (ECT sensor signal less 86�F), engine runtime over 20 minutes in closed loop, vehicle driven to a speed of 55-60 mph, and the PCM detected the fuel tank pressure indicated the same value as the atmospheric pressure in the EVAP Monitor test.
This code sets in 2 Trip(s).First I would try making sure the gas cap is tight. You need to give it 2 trips before it may reset. The other choice would be to replace it, Cheaper than spending money on a professional.
