Apparently, the most common cause is a loose gas tank cap. It has to be tightened until it clicks. Other, more serious faults can cause this indication, but the loose cap issue is widespread. Hopefully, that's all it is in your case!

SOURCE: 98 lexus gs300 codes p1120 p1121

I wanted to start a thread specifically about failures within the throttle body concerning the GS300 (1998 in my case)

My symptons were:
VSC, VSC OFF, and ENGINE Lights would come on, followed by my car going into Limp Mode, where only that last 25% (if that) of the throttle would respond (basically have to floor the pedal to even move at all).

During the mornings, or when the engine was COLD, the throttle operated normal...then once the car warmed up, usually at about 10 mins, the problem would start...it happened intermitantly at first...1 or 2 days over the course of a week, then it became more consitent, until last week it became a daily problem.

The first part I tried was the Throttle Position sensor, which is on the front side of the throttle body, and the easiest thing to replace...this didnt help at all. $300 part from Lexus, $80 part from RockAuto.com (exacly same part toyota OEM)

THE PART THAT FIXED THE PROBLEM:
===========================================
"Idle Valve Motor", which is the larger electrical object next to the TPS on my 98 GS300. Problem is solved.

The Codes I got were P1120 and P1121 - Accelerator Sensor problem. However it wasnt really the Accelerator Sensor, it was indeed to actual electrical Motor that controls the opening of the Butterfly valve inside the Throttle body.

I found the problem by good old trouble shooting, and using an ohm meter to see if the throttle electric motor was getting elev, I found that the elec motor just to the left of the TPS was basically freaking out and shutting down. The Accelerator Pedal Sensor is on the Back-side of the throttle body where the throttle cable connects to, and has a spring on it. It was fine.

GS300's are indeed "drive by wire" concerning the throttle...the cable triggers the Accel Pedal Sensor, which sends a signal to the ECU, the ECU then sends power to the Idel Valve Elec Motor (next to the TPS), which opens and closes the mechanical butterfly valve, then the TPS sensor detects how far the elec motor is actually opening the butterfly valve...its a closed-loop feed-back system, meaning any failure in any sensor will cause the entire systm to fail.

The throttle cable apparently is ONLY there to allow the fail-safe of having that last 10-25% throttle when the electronic system fails...there is a gearbox inside the throtle body which allows the tail end of the throttle to manually engage the butterfly valve...the rest of the time, the butterfly valve is 100% opened and closed via the idle control motor.

SOURCE: Lexus 2004 Sedan. 3 lights on at the same time:

there are many different components to these systems that can cause the lights to come on. if you have the vehicle scanned by an experienced tech with the proper tools he will be able to pinpoint your problem and tell you what it will take to fix it. diagnostic fee is usually one hour of labor.

SOURCE: VSC warning light and check engine code 786 on

The codes points to a shift solenoid issue, Only hands on will be able to fix this. Get the code cleared if the car seems to run fine and see if it comes back. You could have an intermittant issue now but if you do feel a shift issue then you will need to have it addressed at a shop

Hy.I'm Adrian.I have a lexus is250 from 2006 and I just changed the battery and apear the VSC CHEK LIGHT and ENGINE LIGHT.and a c1201 and p2118 error codes.please someone can help with some suggestin


Code P2118 throttle control motor is set when voltage to the motor gets below 4 volts, so perhaps this was set with old dead battery. code C1201 is a vague engine control code, and the VSC vehicle stability code is set anytime you hook up a scan tool other that the dealer's special unit. You must reset the zero point calibration for this to go away. Use your scan tool to erase all codes to see if any come back. This will not turn off the VSC light, however. Follow below procedure to reset zero point calibration.

Zero Point Calibration - "VSC" and "VSC Off" Lights - 2002 SC430 - SOLVED
________________________________________
Friends,
For the benefit of any 2002 Lexus SC430 owners, I'll post the following item dealing with "Zero Point Calibration".
After hours of troubleshooting, I came to the hypothesis that the instructions MIGHT be different from 2002 - 2005 and 2006 - 2010 models. Below are the instructions I followed and WORKED on my 2002 SC430.
If you receive the "VSC" and "VSC Off" lights on the dashboard after a visit to a mechanic (often an independent mechanic using non-Lexus ODBII equipment), this means your "Zero Point Calibration" has been erroneously reset by a non-Lexus specific ODBII tool. This might especially happen if your state requires state inspection via ODBII, and you take your Lexus to a no-name place (like a Jiffy Lube or something). Follow the steps described in Post #6 in this thread to resolve this issue:
http://www.clublexus.com/forums/gs-2...d-vsc-off.html
Note that where you see a reference to a tool called the "SST 09843--18040", substitute that "tool" for a simple jumper cable (such as a short speaker wire) or a paperclip.
Here is the relevant excerpt from the above thread:
"The solution consists of approximately 15 step .
NOTE:While performing the Zero Point Calibration, do not tilt, move or shake the vehicle.
The vehicle must remain in a stationary condition throughout the entire process.
Be sure to perform the procedure on a level surface with an inclination of less than 1%.
Explanation of symbols:
SST (4-inch wire)
DLC3 (OBD-II connector under the dash)
TS (on the top row,pin number 3)
CG (on the bottom row,pin number 5)
(See picture below)
1. Ensure the shift lever is in the ''P'' range.
2. Turn the ignition switch Off.
3. Using SST 09843--18040, repeat a cycle of short and open between terminals Ts and
CG of DLC3 4 times or more within 8 seconds (refer to the specific vehicle EWD for
TS and CG pin location in the DLC3).
4. Turn the ignition switch ON, do not start.
5. Verify that the VSC indicator light is lit indicating the recorded zero point is erased.
6. Turn the ignition switch OFF.
7. Be sure the terminals Ts and CG of DLC3 are disconnected.
8. Turn the ignition switch ON, do not start.
9. Check that the VSC warning light goes off about 15 seconds after the ignition switch
is turned ON.
10. After ensuring that the VSC warning light remains OFF for 2 seconds, turn the ignition
switch OFF.
11. Connect terminals Ts and CG of DLC3 using SST 09843--18040.
12. Turn the ignition switch ON, do not start.
13. After turning the ignition switch ON, check that the VSC warning light is lit for about
4 seconds and then starts quick blinking at 0.13 second intervals.
14. After ensuring the blinking of the VSC warning light for 2 seconds, turn the ignition
switch OFF.
15. Remove the SST from terminals Ts and CG of DLC3.
16. Drive the vehicle for at least 5 minutes to confirm Zero Point Calibration is complete."

VSC/ Check Engine Light


My 2000 Lexus GS 400 just had the VSC/VSC off light and the check engine light come on. I would have to push the accelarator peddle all the way down to get it to go. Took it to the Toyota dealer and the code pulled up as the Throttle Position Sensor was out. Purchased one and having it put in. Will update if this fixes the problem.
