- Incorrect fuel filler cap used
- Fuel filler cap remains open or fails to close
- Foreign matter caught in fuel filler cap
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.
Hi richard mokgwasa, I want to help you with your problem, but I need more information from you. Can you please add details in the comment box?
the petrol only leaks during refuelling at the petrol station. about a liter comes out and then it stops after few minutes. after it stops i drive off and its ok, no leakage it did it for the first time when i was putting full tank and i thought its because its full. and the second and third time s i was just putting half tank. i use unleaded 95 but once a while when the garage doesnt have i will put small amounts of 93 unleaded. fuel consumption is also high.
