Error Indicator Pops Up


Recommended Posts

Hi all,

Recently I've got an error display where the Outside temp display should be.

It shows 'E' when it's suppose to show the Celsius value.

Other symptoms:

1. A/C doesnt activate.

2. Engine idles too low but doesnt die off.

3. Door open warning doesnt go off or intermittent.

3. After 10 secs, an orange light appears where the fuel gauge 'E' is located.

This has happened twice now, only after i've washed my car. Probably water seeped in a sensor or electronics of some sort.

The error disappears the next day (after drying off) and probably the error codes are cleared from the ECU.

Any ideas guys? I have a phobia with carwash and driving in the rain ever since...

hi neuro ...

I noticed that you have IS300 (altezza) in your lexus model. So is it an IS300 or an altezza?

The reason I ask is because I want to know if it is an import or not. The symptoms you mentioned ... how long ago did this start? How long have you had this car?

is it possible that (if yours is an import) your car was a "flood" car from japan? You can check this by sticking a knitting rod thru the floor carpet and see if there is brown residue when you pull it out. A flooded car would have disparate electronic errors like you mentioned above.

Hi bernard,

the problem only started these few weeks. and no, its not flooded.

It only happened after a car wash, maybe I sprayed the water hose where its not suppose to be.

BUt its a strange symptom. where is the sensor that causes this?

The compressor switch perhaps? Thru the front grill??

Anybody out there knows?

Is yours imported altezza too? How do u know about these flooded cars?

I've seen the E marking on the outside temp gauge on my Altezza before, but none of the other symptoms you describe.

The Battery was very low at the time, so I just assumed this was the cause. I've seen it a couple of times, and it has always been OK the next day.

Not much help I know, but your not totally alone...
