Engine Light on 2000 Camry

I had the same problem on my `02 at around 129,000 k

It was diagnosed as the vacuum switch on the charcoal canister.

After the diaganosis the light went out for about 50 k and then came on again.

Diagnosis was about $35.00-$40.00 Canadian

I got a price of over $500.00+ Canadian to replace this vacuum switch from the dealer.

Not just having got off a turnip truck ?I went to two other dealers for a price to replace the vacuum switch.

Both said about $125.00 +taxes. so I went with the closest dealer after getting a written estimate on their letterhead for the job.

(This prevents any surprise "we didnt count on **** extras over 10% of the bill, as prescribed by law.)

And thats what it cost me and the light is still out and car runs fine.

Incidentally you dont really need the vacuum switch until its time for your emissions test.

The emissions test comes up in August so I`ll see if its ok then.

Hope this helps

You need to read out the code with an OBD-II scanner. In the US many parts stores will read them for free. You may have a completely different problem.

If it's evaporative system related I don't think the gas cap was ever the problem. Back in 97 the problem was the then new canister design, a real flop. But the later ones shouldn't disintegrate from the inside and the vacuum switching valve may be the culprit.

I'm not sure if the following is the correct one, but looks like it, $48.79 USD + shipping.

Since Alberta has no emission testing that is compulsory, I did nothing when I had that diagnosis.....years ago. 99 Camry STILL runs perfectly fine WITHOUT any repairs on bogus symptoms.

I wouldnt have done it either except for the emissions test.I really dont know what action the vacuum switch on the canister has on emissions.

I am mechanicall adept up to a point (having worked on my own cars for over 60 years until I got too much arthritis to do it myself anymore) but these new cars have me baffled.

Just to Update: The light did shut off once again. It is so weird. Next tome the light turns on, I will take the car in to get diagnosed appropriately. Thanks for all the help and great reply's!

Been there done that. Different grades of petrol will do that when the seasons change but it really is one or both O2 sensors. One in the engine area and the other near the cat converter. Replaced the engine one and went fine for awhile the light on again so replaced the other one. No light for over a year. Repairs were less the $100 US. 1999 Camry CE with 4 cylinders.

The light turned on once again, this time, I jumped at the opportunity and took it in to the service center for a diagnoses. I was told that the car is sensing odd temperature fluctuations. They tested the heat valve and it was working properly. In addition, I haven`t noticed any odd climbs in temperature to suddenly fall to a cold temperature. They reset the check codes, so the light is off once again. Should I have it looked over by toyota? or just forget about it?

Because Toyota charge like wounded bulls,..I'd wait and see if you can glean anything more from your gauges etc. It doesnt look like anything is in danger of blowing up.

I took the car to Toyota and had them Diagnose it. Turns out it needs a new thermostat. The price installed is about 90 bucks Canadian. No light yet. Thanks for all the input and help from other Camry drivers!
