Hi All,

Right...got myself a 2000 Lexus is200 se (2000)

A day after I got it, the Engine light came on and the TRC light started flashing. The car started idling low and rocking slightly, almost like it was missfiring. Instinct told me it was a coil pack so I tested them all (all fine) I even swapped all of my step fathers coil packs over as he also has is200 se but made no difference.

I have done a fair few things to it and it just isn't making a difference. I clear the faults and the lights come on again :megaangry:

The list of things I have done so far are as follows...

1. Full Service (inc: plugs, oil flush, all filters etc)
2. Took throttle body apart and cleaned it all, tightened up throttle cable as was sightly loose - Still slightly lumpy

The only thing I can think it is now is the 'oil control valve' or 'camshaft oil control valve' (what ever you call it)

Can anyone help as Im rapidly loosing the will to live now. Anyone having the same issue or can give any advice would be great.

Diagnostic machine will not pick a fault up - Which doesn't help but mind you I have got a non-standard head-unit in and I have heard that they interfere with the diagnostic checking!

HEEEELLLLLP???!

If there are warning lights illuminated there will be fault codes stored but some generic code readers will not communicate, see if a professuinal scan tool will work at a local independent or at worst your local Lexus ( read expensive) dealer.
You have changed the most obvious parts but why is the TRC light also coming on? It will be more expensive if you just start making assumptions and replacing random parts rather than getting the codes and being accurate in the diagnosis.
How is the timing belt has it been replaced at the correct interval? The reason I ask is it may if well worn/overdue have slipped a tooth or two but again that would not explain the TRC light.
You could of course have 2 different problems.

Hi mate, thanks for the reply.
Ive had the Traction Control tested and the car will not wheelspin with it on even though its flashing. Turn it off and it wheel spins very well indeed! ;-) The timing belts been done. Had that checked too. The timing lines marked are bang on.
The diagnostic reading was done with a Snap-on machine (15,000 worth) but it just didnt read anything. Im half tempted to take the stereo out to stop interference and get my mate to plug it into his system!
If that doesn't pick anything up, nothing will! :-(
I dont particularly want to take it to lexus to be honest.
Appreciate the help with this though mate. Thanks again!

Hi there, did anyone find out what the exact problem was with the engine management light is flashing along with the TRC light??

 

We've changed coil pack, plugs, crankshaft sensor, cleaned camshaft sensor and throttle body valve and done an oil change and engine flush - still no luck and coil 1 keeps coming up on the diagnostic.   

 

My hubby is not sure where to go next :megaangry:  - any help would be great!

 

Thanks all

:)
