welcome to the site, did you change it yourself or did you get it done in a garage? What model is your Altezza? Is the car still driving the same?

bring it back to the garage and see can they pull a diagnostic code from it, and then check it against the list Rob posted

Engine light

If the timing belt belt wasnt replaced correctly, The timing marks might be off,even one tooth on the cam or crank pulley will bring on the light,The fault code should be camshaft/crankshaft synchronisation i would advise to get it checked on the suitable diagnostics.Thats what it sounds like to me its easily done mistake

If the timing belt was fitted right it might possibly have a slight back fire like bad spark plugs, or slight jerking in the engine when its ticking over........

Check all sensors have been pluged back in & havent been damaged.
My mate had a similar problem after he had his belt changed & it turned out to be a damaged cam position sensor.

The Garage use a tester to bring up the code and the error code was PI346. When i CHECK THE CODE I GET TH EBELOW MESSAGE

DI−1 22
− DIAGNOSTICS ENGINE
LEXUS IS200 (RM684E)

DTC P1346/18 VVT Sensor/Camshaft Position Sensor Circuit
Range/Performance Problem (Bank 1)
CIRCUIT DESCRIPTION
Refer to DTC P0335/12, 13 on page DI−81.
DTC No. DTC Detecting Condition Trouble Area
P1346
Deviation in crankshaft position sensor signal and camshaft
position sensor signal (2 trip detection logic)
S Mechanical system (Jumping teeth of timing belt, belt

S Engine ECU
WIRING DIAGRAM
Refer to DTC P0335/12, 13 on page DI−81.
INSPECTION PROCEDURE
HINT:
S Perform troubleshooting of DTC P0335/12, 13 first. If no trouble is found, troubleshoot the following
mechanical systems.
S Read freeze frame data using hand−held tester. Because freeze frame records the engine conditions
when the malfunction is detected. When troubleshooting it is useful for determining whether the vehicle
was running or stopped, the engine was warmed up or not, the air−fuel ratio was lean or rich, etc. at
the time of the malfunction.
1 Check valve timing (Check for loose and jumping teeth of timing belt) (See page
EM−25).
NG Adjust valve timing (Repair or replace timing
belt).
OK
Check and replace engine ECU

Yes your car will start if the timming is off but it would be harder to start and it wouldnt run as smoothly as it should you should avoid driving it untill you get it cheaked out as it could cause damage to the valves or pistons .I would bring it back to the guy who fitted it if the timming is off its his fault but if its a sensor it might not be

Like Mark said it will run unless it off the scale. We had several cars into us with the same proplem. Recheck the timing if its not that then camshaft sensor...

Agree with all of the above plus the VVTi will be able to correct the valve timing up to the point where it goes "out of range".

So take it back and get the timing checked.
