as far as i konw the TPWS system are standard on 04 and up LS....

whats the pressure after the car sat for an extended amount of time? on the early 04 ls , lexus had a TSIB regarding the TPWS and it involves the ABS/VSC ECU to be changed due to an updated software in the ecu for the tire light. you can probably bring the car back to the dealer and have them check your VIN and see if it falls in the replacement vin range. keep in mind the system takes up to 100 miles for it to initialize properly so tire pressures must be even and correct during the reinitialization time.

more so the ecu than the TPS, also it was bank specific so if its ecu related it will throw other codes and if its tps related it will be both banks..... I would check the OCV on bank 2 and go from there.

check for a seized caliper slide pin on the front calipers, most of the time the dust boot are left not covering the pin after a brake repair and over time this cause moisture and dirt to get into them and seize them in place, and it will cause you exact concern. Thanks for the reply I have since taken my car to the Lexus dealer and was told the calipers needed to be replace which I don't understand the car only has a little over 51,000 miles. This is my 3rd Lexus, I previously owned a 1995 and 1998 ES300 never had a problem sold the 1995 to a friend with 110,000 miles never had a problem but normal wear and tear my friend still owns the car and he is very happy. Desided to trade up for the GS300 but seems this was a bad choice. Personally they all great cars and i definally like the GS over the ES both in style and performance, thats just me.... :) Its a very common thing on the GS with the pins seized in place due to a misplaced boot. if you dont mind me asking, which dealer did you bring your car to? I took my car to Lexus of Rockville Centre in New York How do you like the service department ?

The vvt-i oil control valve needs to be checked for a possible malfunction along with the cam sensors, bank two is the one where the oil cap is located. if you are mechanically inclined you can remove the engine cover and see the oil control valve, it has a black connector and the valve body is gold in color it gets attached to the cylinder head with one 10 mm bolt, remove and pull it out, fairly easy to do. you can bench test it or just get it replaced......

You might want to check both of the cam sensors located on each sides of the cam sprocket and especially the crank sensor on the engine with an oscilloscope but a voltmeter can do also. its better to check the signal at the engine ecu to elimate all the possible wiring fault. also there are two igniters located around the master cylinder area which controls the primary ignition circuit and also confirms the ignition signal to the engien ecu. some rare cases they go bad, but i would not replace them with out checking the basics first Good luck ....

check under car where you shift linkage is attached to the neutral safety switch, make sure its aligned properly and not bend in anyway. if all ok than i would check the shifter console itself and make sure thats working properly and go from there....

theres a EGR position sensor on top of the EGR valve, make sure thats working properly with a volt meter and find the EGR VSV located on the VSV rail on top of the engine by the intake manifold and check the VSV operation, make sure theres vacuum going to the EGR modulator and out to the valve... i've seen a couple of the EGR position sensor malfunction that caused the same problem. Good luck

hey sorry to hear that.... but from what i know, the lexus/toyota vehicles uses something called a "floating type differential" on their rear wheel drive vehicles, which means the differential is mounted to the rear subframe via RUBBER bushings, i hate to say it but they all thump under the right conditions, very much like the driveshaft clunk you find on the GX and the LX. changing the bushings will probably mean the rear subframe gets changed and after that it will most definally return within a short period of time. i would still have the dealer double check your driveshaft play and make sure its within spec. and go from there....good luck

Theres a setting in your CBES( customized body electrical system.) feature that can enable the sunroof to open via the wireless remote. your car is mostl likely disabled. check with the dealer and have them access the CBES program and go into the settings and check.

there are two knock sensors, one for each bank. it might be the other one thats causing the light to come on. also you shoould have him check the harness that comes off the sensors, it gets connected to the main engine hearness around the thermostat housing area, just to be sure. Again this is based on the fact the engine is not knocking of course.. good luck Thanx so much for your feedback! i appreciate it! :D Anytime, good luck with the car. :)

its an issue with the 02 and up model ES.. the shifter console needs to be repalced. its an internal open in the console, when selsecting gears it does not output the proper voltage to signal the combination meter ecu to have the "D" indicator to be turned on.

if no one ever tried to gain access, then most likely the hard drive shorted, you can gain access to the disk its under the passenger seat and eject it from the hard drive and take a look to see if any scratches are present. if not the disk is ok to reuse but if there are visible scratches then the hard drive and the disk are going to need replacement. since its a o4 the parts should be in warranty if you can locate a lexus dealer around you. good luck...
