Question about Kia Sportage

Emission control system

Vehicle smells of gasoline, inside and out when operating. No visible signs of fuel leaking. Seems to be just vapors. A repair shop gave up looking for a solution.

    Interesting to note. But what is the solution? Replace the fuel tank? Is it really the fuel tank or connection to the fuel tank?

  • davegml Dec 31, 2013

    Yes, new tank. I've not done one myself but we've had a couple through our workshop. On both occasions they ended up at the dealer with the customer "talking" to them.

SOURCE: gasoline smell off and on

Have them check EGR tubes, and any hoses, or tubes running to the exhaust. My guess is ones leaking while driving & getting drawn up into the incoming air at the cowl.

SOURCE: smell gasoline after turning off the engine. 2006

I had this Problem on my S-10 it was a bad fuel injector, the problem was when i looked for the leak it would evaporate quickly, use a flash light and look at each of your fuel injectors as soon as you turn of the car. If you do it yourself it is an easy fix, mine cost 12 dollars and about an hour to replace.

Evertime I start my 2000 alero oldsmobile I smell gas, any reasons why?


Usually, it's fuel vapor from an emissions hose you are smelling.If there are no visible signs of a fuel leak---damp or wet at the injectors, connections, fuel filter, then I would suggest a smoke check to find the emissions leak

Hi,

P0455 = Evaporative Emission Control System Leak Detected (gross 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
All the best

Strong gas smell in vehicle


Take it seriously! Gasoline as a liquid is not flammable but the vapors are! Have it serviced and diagnosed by a professional unless you are mechanically inclined. If you were mechanically inclined I would assume that your question would have been more specific. Gas vapors can come from multiple sources. The seals/gaskets on the inlet. The vapor emission filter. Broken gas line. Bad air fuel mixture. Leaking fuel rail. Damage in-line fuel filter. Etc.

Trouble code shows po452 which is the evap


P0452 Evap.Emission System-Pressure Sensor Low Input

The evaporative emission control system prevents hydrocarbon vapors from escaping from the fuel tank into the atmosphere where they could form photochemical smog. Gasoline vapors are collected in the charcoal canister. The Fuel Tank Pressure Sensor (FTPS) is an integral part of the evaporative monitoring system. The PCM monitors the FTPS signal to detect vacuum decay and excess vacuum. The FTPS measures the difference between the air pressure inside the fuel tank and outside air pressure to check the purge control solenoid valve operation and for leak detection in the evaporative emission control system by monitoring pressure and vacuum levels in the fuel tank during the purge control solenoid valve operating cycles.
