Question about 2002 Hyundai XG350
Car runs and drives perfectly. Timing Belt & Water pump were replaced approximately 1000 miles ago but doubt this would be related. The vehicle currently has 102,000 miles on it. The check engine light recently illuminated and two local autoparts stores both read the same three codes, p1191, p1193 & p0446. The only issue I have experienced with this car is that occasionally the instrument panel and headlights appear to slightly dim and brighten for no apparent reason. Both while running the air conditioning and when not. Any direction or advice will be greatly appreciated. Thank you.
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..
