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.

Visit http://www.obd-codes.com/trouble_codes/ and
for the codes you have.
So the 171 and 174 indicate lean fuel/air, the 1191 and 1193 indicate the car is in limp home mode. And 1632 is a traction control issue.
The lean mixture might be as simple as a plugged fuel filter, or as complex as trouble with the injectors, the throttle position sensor, fuel pressure regulator, or fuel pump. How long since you replaced the fuel filter? If it has been close to or beyond the recommended interval this is a cheap ($20 for the part) and fairly easy thing to try.
The lean fuel/air could be the cause of the limp home mode.
The 1632 code is a traction control system malfunction. Could be an intermittent issue or occurred because the engine is operating erratically. With this code the car should still run fine, but the TCS won't work properly.

SOURCE: I have the engine check
Welcome to FIxYa.com The P0401 code is Insufficient Flow Exhaust Gas Recirculation System. I would clear the codes first and run engine for two min and re-check codes. Write to me of the findings and we will go from there. Regards, Lee Davidian A Four Thumbs up ^^^^
is appreciated for answering your question. Thank you, Lee
Description of codes are:
P01600 - Serial cable malfunction-- check connection,
Po115-Coolant sensor-indicates a open or short-circuit in the engine coolant temperature sensor circuit.
The code is set when the engien computer detects less than the requested amount of EGR flow when the engine is hot and is under load.
What usually sets the code is an inoperative EGR valve, or a carbon clogged port under the EGR valve.
On your engine, the EGR valve is vacuum operated, and there is a little computer-controlled EGR solenodi valve in the vacuum hose that detemines how much vacuum the EGR valve gets. If this solenoid is bad, or there is a vacuum leak in one of the hoses, the EGR valve won't open when it should setting the code.
Since the dealer already cleaned the EGR valve tube, I would suspect your problem is likely due to a bad EGR solenoid valve or a leaky vacuum hose to the EGR valve.
Here is the EGR solenoid valve part number and list price:
P/N 3946038750 $40.59

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..
