DTC #33,34 "Air outlet damper position sensor circuit". Code 33 "Short to ground or power source circuit in air outlet damper position sensor circuit. This sensor detects the position of the air outlet damper and sends the appropriate signals to the air donditioning control assembly. The position sensor is built into the air outlet servomotor assembly. If you need a flow chart Pm me (it may take me some time to respond) with your E-mail and I will send you a PDF file.

I would look at the coil first.

When you buy a key for the older (93) lexus cars. You get one key and a ROM (read oy memory) chip. To replace the key you remove the old ROM chip and install the new one that comes with the key. No programing.

The "catch" is that thay are NOT LEXUS wheels. Thay are aftermarket. We put wheels like those (with the same "L" logo) on all the time.

I have been toying with removing the mast ant assy and useing (a) the ant out of a toyota solara conv. Or (B) useing a glass mounted ant and smothing the hole in the fender.

I would not recomend doint this for the reason that most of the time when we try to "fool" one of the networked systems it dosent work. The Nv will not understand why the GPS has the car moving but there is no speed input. I'm shure that it will kick a NAV code. Now There is a slpice (4E) at the center dash and junction block (above the glove box) with 2 white/red wires. These are your speed input wires. If not there on the right side of the dash/dash support there is a conector (IG1). It is a 18 pin conector with white/red wires in pin 8 and 18. Pin 8 is for the NAV Ecu and pin 18 is for the Amp.

The "NAV" and "Handsfree" system is all controled by Navigation ECU and a few others. The Bluetooth controls are programed in to it and there is no way that I know of to change it. (my prius customers ask the same thing) Sorry.

That's it.

It's in the junction block on the Left kick panel. The block is in a "p" shape, the horn relay is at the top right then the next row below it is the turn signal flasher and the seat heater relay (if equped). hope this helps.

Blue/Gray smoke is normaly Oil. It could be valve stem seals or you may have pulled a little oil past the rings with a little carbon tha broke off on the hard run. keep checking your oil.

Check to see if anything was unpluged down around the shifter. There is a shift lock control switch that workes with the shift lock ECU. The shift lock ECU controls the Key interlock solenoid on the ignition switch. The shift lock control switch will be a 3 wire conector, Green, Green/White and Green/Red. The interlock solenoid is a 2 wire conector, Blue and White/Black. The shift lock solenoid is down there by the shifter to and it is a 2 wire conector, Light blue and Light blue/Red. Hope this helps

There is a oil seal around the spark plug hole on the valve cover on the 1UZ-FE (V8) I would check around the puddle to see if there is a trail of oil from one of the holes.

What year is your SC400???

First off, 2k for a headgasket is a little much. As for a 2jz-gte of a 1jz-gte swap there is nothing to keep this from hapening on one of them. I have worked for toyota for 9 years and one of my techs has for 25 years and this is the one week point on the I6 toyota motors. From before the 5mz-fe and the landcruiser this has always been a prolbem. Some pepole are using metel headgaskets to fix this. I have talked to techs that are torqueing the heads down to 100ft with out any prolbems. My head kit is sitting and waiting for mine to pop.

Most Toyota's dont have a interference motors. Some of the VVTI and VVTI-L motors are but not the older ones. If it's stock the 2JZ-GE and 2JZ-GTE are NOT interference motors.

The "cat's" burn off HC and CO (un-burned fuel) from the motor. The O2 sensores change from 0v to 5v with the amount of HC (un-burned fuel) in the exhaust passing over them. The ECU reads the O2 sensors and leans out or richnes up the fuel mix to the engine. With Toyota/Lexus the readings that the ECU recives is with a "cat". If the "cat" is missing or damaged it will kick a DTC (diagnostics trouble code) and turn on the "check engin light".
