FIXED !! Replace throttle body assy and has been working great for a month.My wife is happy.
-
Called a mechanic I know at Lexus.Went thru what I had done replacing the tps.He said when that code comes up the replace the throttle body assy.Its preset at the factory and cost $1261.I called parts masters and a used one is $300. plus shipping.Any thoughts?
-
Pulled the TPS out again and checked the resistance to the old unit and both read the same.I am only getting 4.7 volts where it supposed to be 5vdc.Possible loose connection?Just drove back from the shop and running fine.Go figure.....Where does that 5 vdc come from? Thanks for your help! Tim

Thanks for the pdf !There is a slot on the TPS to move it a little.Replaced the batt in feb for a intermittent VSC light.Seems like half the systems run thre that circuit.The LS 400 has 185,000 miles and the engine is so quiet you can hardly hear it.Great vehicle !
-
Replaced the position sensor assy.I also had a P1120 code but that is gone now.Put it on a Snap On code reader and P1121 indicates a volt fault.Intermittent Vsc/check eng fault.Checked the connections and everything looks good.Any ideas ??

Finally had a bulb on right front go out .... How do you get to it.

Hello,check your cig/assy fuses.Had that happen to me on my 1999 ls 400.Go figure!!

Experienced same intermittent problem with 99 LS.Loose connection in dash ?Try banging on top of dash and see if it pops up.Good luck!!

It's that time !Any ideas on where to purchase a set? They are $60. on special order thru Auto Zone.Looks like they just snap on.

The LS 400 is a chill out car.Set the cruse and let it run.The nearest car is the 1970 Mercedes 300 SEL 6.3,what a rocket.

..................fixed !! Ended up being the cig lighter 15a fuse,go figure.

Batt had loose connection which caused console indicators to flash.Fixed batt but think surge caused fuse somewhere to blow.Checked gauge and panel fuses which are ok.The car runs great but dash is black!Any ideas......Tim
