SOURCE: 2003 Pontiac Bonneville Interior lights dont work

There is another fuse box under the back seat that has the fuse for the interior lights. I have the same problem. I keep replacing fuses but they keep blowing. I don't know what to do.

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: 1998 Ford F150. windshield wipers,interior

check to see if you have corrosion in the fuse box or the GEM module, by removing the fuse box completely, disconnect the battery, take out the two screws and two 8mm bolts that hold the fuse box in, it will take some maneuvering to get it positioned right to disconnect the two wiring harnesses from the fuse box, they are bolted through the middle. Once removed, take the GEM module off the back of the fuse box and look for what would be something like the same corrosion you would see on your battery posts, usually one of these components is corroded and causing the problem, my buddy got a replacement fuse box for his from a wrecking yard for only 15 dollars, with all the fuses and relays. If you have this corrosion, then you probably have a windshield leak at the lower left hand corner of the windshield, it lets water drip onto the fuse box and GEM module. Hope this helps, let me know

The fuse for the fog lights could be in the Fuse Convenience Center under the dash or in the Engine Compartment. It is most likely a fuse, relay, or could be the Fog Light Switch. You need to test each one starting with the Fog Light Switch first,

Tag light is not working on 2002 Lexus GS300


I'm guessing you are referring to the license plate light. There are two bulbs. Pretty rare for both to go out at the same time. It could be the fuse. You can check if the fuse location by looking at your owners manual.

I think the license plate bulb is W5W LL. (Check to make sure). You can find the bulb a your local auto store, Walmart, Target, etc....
