SOURCE: Engine Light/tighten fuel cap

Good Day,

Sounds like your fuel cap needs to be replaced, there is a rubber seal in there to which keeps fuel pressure up, when this seal goes bad you get a drop in pressure and your engine light will come on. Replace the cap with a new one. As far as your lighter ports that is probably due to a blown fuse and unrelated to the fuel cap issue.

Hope this helps

SOURCE: check engine light came on the day after refueling

Did you refuel while leaving the engine running? Have OBD scan done before light resets. Temporary errors are cancelled after a number of start cycles.

SOURCE: emission light on 2005 a4 cab comes on

Dear Dave, Audi 4A for us in Cyprus as Mechanics we say that is the car which feed you and your family, I mean is the car with lots of every little while remember to start a problem. Now as what you said for the emission light came on and then off and mechanic said there is nothing wrong ,believe him. Now is on! well ask your mechanic to lift the vehicle up and find the Oxygen sensor to remove it and clean the threads by means of grinder-brush and also using carb cleaner to clean the carbonated surface of it and back on. remember to put contact cleaner on the connector. Also ask him to remove and clean the throttle body . After to do the re settings ( ADAPTATIONS ). good luck.

Emissions System warning keeps coming on. Mechanic & muffler shop disagree.


Start with the first mechanic who replaced the battery and have them check the charging system. (Alternator) They should have done this when changing a battery, to rule that out as a problem in the first place. Explain the problems you have been having, as a bad charging system can cause all sorts of electronics problems and have them check the engine codes and have them explain what they are.
You could also go back to the muffler shop and tell them their sensor replacement did not fix the problem and have them correct their work.

My question is on my acura mdx 2003. The left front wheel was worked on and somehow the mechanic damaged the sensor there. I guess the abs sensor. This made the ABS, VSA,VTM-4 and a triangle light came on....


When you clear the codes and the problem has not been fix after 10 miles of driving the warnings return. I am sorry but I am not sure what is causing the indicator lights. Have you looked up all the remaining codes?

Error code p1457


P1457 ACURAP1457 ACURA - Evaporative Emissions Control System Leakage EVAP Canister System


0 Comments ' Add YoursPossible causes- Missing Fuel cap
- Incorrect fuel filler cap used
- Fuel filler cap remains open or fails to close
- Foreign matter caught in fuel filler caphelp.png Help with thisSymptoms- Engine Light ON (or Service Engine Soon Warning Light)
- Possible a noticeable fuel odor caused by the release of fuel vaporsP1457 ACURA DescriptionThe 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.

Check fuel cap light went on today. how do i fix it?


If you refueled your vehicle with the engine running, this is what caused the light to come on. Otherwise, your fuel cap may not be on correctly. Check your fuel cap and make sure it is installed correctly. Be sure that it "Clicks" when you tighten it. Then drive the car for a couple days and the light should go out on its own. If it does not go off in 2 or 3 days, then you need to have your evaporative emissions (fuel tank) system checked for leaks.

We just bought a 05 chevy equinox 2 days ago. Last night the "service engine"light came on. My husband went to check the oil and cant find the dip stick.


If you don't tighten the gas cap (make it click at least four times) when refueling it will turn the check engin light on. The dip stick is located in the front of the engine and is a yellow loop.

S40 Warning Lights


Faults can happen from day one, on. That is why there is a warning system.
If the warning light is on, you must access the computer system to access which fault code is present. Many different companies manufacture tools to do this from an inexpensive generic one from Launch Tech of China to the original factory unit made for Volvo by Balco. Depending on the fault code, the most common one that I see is caused by the fuel cap either installed incorrectly or not fully tightenned. Check your fuel cap and if it is not installed correctly or not fully tightenned, please re-install. If the fuel cap was the problem, the warning light will go off by itself in a few days.
