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..

P1193 error code car wants to stall when stopping and accelerating


P1193 = Detected engine speed below 470 RPM. There are several possible causes/components which can contribute to this drivability issue. ELECTRONIC THROTTLE SYSTEM (ETS). In most cases, an ETS related DTC will set in pairs of codes. The first code denotes the related system or component. The second code is for the specific fault detected.
There was also probably P1191 - limp home

For this issue, on frequent occations I've found the throttle position sensor (TPS) (potentiometer) had bad spots in it and subsequently sending erratice signals to the ETS Control Module (additionally, the throttle body and plate had carbon buildup inteferring with the intake air flow. Also check for air leaks (intake air hoses, vacuum lines & tubes for cracks/leaking). Clean the throttle body & plate. Bench test the TPS. You also have an APS (Accelerator Position Sensor) located on the RH side engine compartment near the firwall next to the strut tower. These are the initial components to check/examine. Replace as needed.

Year 2001 XG300 P0115, P1159, P1191, P1193, P0115


P0115 - Engine Coolant Temp Sensr - open/short
P1159 - Variable Intake Motor Malfunction

P1191/P1193 Limp Home Valve - Low RPM

First, clean the throttle body and check for anything which might obstruct AIR FLOW to it.

The P1159 is the Variable Intake Motor Malfunction. this motor is either 'OPEN'... or 'CLOSED' position. It is located on/in the intake manifold (plenum) and is only opened when cruising... it is closed at idle. If it sticks 'OPEN' is can cause drivability issues.
