1995 corolla check engine light

Hi. I have a 7afe 95 corolla with auto trans. Ever since I bought the car the check engine light has been on and off. The transmission shifts at the same speed regardless of how hard I push the gas down. I can shift manually and it works alright. Whenever it rains alot, then the transmission shifts normally and the check engine light goes off. Then when the car dries off the engine light goes on and off again and the car shifts like it did before. Any ideas?
I would bring it to get checked out, but I thought I would check here first to avoid a 40$ check engine light test.


Thanks,
Andy

did u ever think that it could be other stuff instead of the tranny... could be lots of stuff that will make the check engine light go on... just start w/ the basic... could be a simple light bulb or fuse or watever...

Yes. I have considered that. It is most definitely eletrical because I can shift it manually and it works correctly. I was just wondering if anybody had a similar experience with an electrical problem relating to the check engine light and the transmission not downshifting.

thanks,
Andy

have you tried turning the key to on, short the TE1 and E1 connectors in the Diagnosis connector. Then count the flashes in the sequences of order and let us know. I will find the code in the book. If it it flashes constantly there are no fault codes recorded. Then you need to go into test mode and drive it. I will let you know how to do that if you need to.

Follow thespud's guidance and find out the code first. Stay in touch, thespud stated that has code book, but, I don't. I know how to find out or read the code.

Here is the procedure
  1. Make sure the battery is fully charged and voltage is at least 11 volts.
  2. Make sure the throttle valve is fully closed. DO NOT PRESS THE GAS PADLE.
  3. Place the gear shift lever in Neutral. Turn all accessories off.
  4. The engine should be at normal operating temperature. Start and Warm-up the car for a while. And once warmed-up turn it off.
  5. Using a jumper wire, connect terminals TE1 and E1 of the Data Link Connector 1 (DLC1) located under the hood in engine copartment possibly near Intake Air filter and Brake Master Cylinder marked "DIAGNOSIS".
  6. Turn the ignition switch ON, but do not start the engine. Read the diagnostic code by the counting the number of flashes of the malfunction indicator lamp.
  7. Codes will flash in numerical order.
  8. If trouble code exists, Check Engine light will flash once every second. The number of flashes will equal first digit of trouble code. After a pause of 1.5 seconds, second digit will be displayed.
  9. If more than one trouble code exists, next trouble code will be displayed after pause of 2.5 seconds. Smallest value trouble code will be first. Once the list is completeted Trouble codes will be repeated after a long pause.
  10. If no faults are stored, the lamp flashes continuously every 0.5 second. This is sometimes called the Normal or Diagnosis System Ready/Clear signal.
  11. After the diagnosis check, turn the ignition OFF and remove the jumper wire.
  12. Find out and note-down diagnostic code(s).
