Outside temperature gauge - 2000 Camry

[cthompso]

Gentlemen:

I recently had the "Check Engine" light come on in my 2000 Camry with
39,688 miles. I took it to the local dealer and they did a comuter check
and said "The light is now off but you may need a vacuum switching light
on the airbox if it comes on again."

About a week later I pushed the button on the clock to check the outside temperature, and the car thermometer read 77F when the thermometer at
my home read 90F. The car thermometer has always been very accurate
before now.

My question is, has resetting the Camry computer had anything to do with
the outside temperature gauge in the car now being off by 13F, or is there
no connection with the temperature gauge and Camry computer?

I also wonder what they did to turn the Engine light off. The invoice simply
says "CK ENGINE LIGHT ON CK AND ADVISE."

Thanks in advance for any comments.

Did they tell you what the exact code was?

[cthompso]

Thanks for your quick reply.

No, they did not tell me what the exact code was, only that the "CELO
Diagnosis was the vacuum switching valve on airbox may need to be
replaced at a cost of $122" if the light comes on again.

I thought it might have just been something like the oxygen sensor in
the exhaust emissions control was dirty, or bad. I don't have any idea
what the vacuum switching valve on the airbox does!

Welcome to the AF!

Is it possible you measured the inside temperature of the car instead of the outside temperature? Many temperature readouts have the option of monitoring either one.

No, it is not possible to measure the temperature inside the car on the 2000
Camry LE. The only choices on the dashboard clock are, time, temp F and
temp C. When you first turn on the ignition you get the time. When you
push the button one time you get external temp F, the 2nd time external
temp C, and the third time back to clock time.

Both the degrees F and C are off.
