Malfunction Indicator Lamp

2000 Lexus IS200 Sports Luxury, 6 speed Aussie car in Ireland.

I just had my first timing belt service this week and the car has travelled 150,000km (93,750 miles) from new. I have never had a warning light illuminate until I picked the car up after the service. I drove for 20 minutes and stopped. No problem. Later i drove for 5 minutes and I get a warning light. I returned to the dealer who reset it and said it was a phantom warning, to do with the Key being recognised by the immobiliser. I drove away and 80 miles down the road I stop the engine again. (To this point, no warning light). When I drive on from here, I get the same light comming on. It is driving me crazy. Can anyone advise on how to overcome this problem? Car opens, locks, starts, drives etc. I am scared that I will be left on the side of the road with no power or something. The dealer is 140 miles away from where I live and offers no explanation as he is stumped by the problem

Oh, the timing belt at 150,000km... Well, I saw the one that came out. Was very lucky it had not broken. Aussie IS200 manual says to change at this milage. I will believe and take the local advice here to do it at 100,000km (62,000 miles).

Can anyone offer suggestions as to cause and/or fix?

I am going back to the dealer tomorrow. The lamp is still on and they have changed their minds and now say it is something to do with the camshaft? Can anyone throw some light on this for me?

Do you mean the "Check Engine Light" - the orange light at the top right of the dash?

99% of CEL errors are emissions related, suggesting that you have a faulty O2 or Lambna sensor somewhere on the exhaust.

Dealer said camshaft position sensor. Would this be related to his fitting of the timing belt considering it started within 10 milesof the garage after the belt was fitted?

Quite possibly, but a faulty CPS usually means the engine won't fire up.

Car fires up and drives. If the sensor is faulty and they replace the sensor I will be happy. I am concerned that the sensor is not faulty and that the error message is accurate. It would be strangely co-incidental that the sensor becomes faulty immediatelyafter the timing belt was fitted. I strongly suspect something went wrong when fitting the belt in relation to the camshaft position.

They want the car for the whole day.
