Pulling a code on a '94 Toyota Camry

Got a '94 Camry, 2.2L, 4 cylinder engine with a check engine light on. When you want to find out the problem is it's not like plugging a scanner and reading what the scanner finds out what the DTC(diagnostic trouble code).

This earlier model uses an OBD1(on board diagnostic). I believe cars made from '95-present uses the OBD2.

Well, to find out what the code is you would have to pop up the hood of your car and locate the DLC1(data link connector). It should be gray and to the left, close to the upper strut mount. Next you would have to connect a jumper wire to terminals TE1 and E1 of the Data Link as shown.

Also make sure...
  • Battery positive voltage 11 volts or more.
  • Throttle valve fully closed.
  • Transmission in park or neutral position.
  • Air conditioning switched OFF.
Then go and turn the ignition key to the "ON" position and count how many blinks and pauses the check engine light does.

Well there it is...on how to pull a code. It wouldn't do any good if you don't know the meaning to it so I suggest to get a manual or you could ask me to find out.
