You might want to check to see if you have a blown fuse. the fuse you are looking for is in the fuse box located inside the vehicle. It will be in the number 3 position (see picture below) and is a 20 amp fuse. this fuse is for the OBD connector and the cigar lighter. If this is blown your connection will not work. I hope this helps you and good luck.

Where is the obd port

Yours will be only OBD-1, and there are very very few places that can read OBD-1 anymore. Some Subaru dealers still have a Subaru "select monitor" scanner for OBD-1 cars. You also have to know which connector is the OBD-1 connector, it's among many connectors that are up under the drivers side dash . I hope this info helps.

2003 ford explorer obd will not read

Check the fuse in the block in the a-frame on the left side of the dash. One of the fuses in there controls the link between the OBD port and the computer. If that fuse is blown, then you'll never get a connection through the OBD port.

  • Hi, I can help.

  • You don't have an OBDII port. You have an On Board Diagnostic set up or just plain OBD I.

  • The connector is under the dash. Take a paper clip and put it between the number 1 and number 2 ports. When you first stick the paper clip in you will get 1 blink and a pause the a 2 blinks which is normal and lets you know that the the OBD computer is reading properly and your codes will shortly follow in sets of two.

  • If you have any comments please feel free to leave them here.
  • Hope this helps and thank you for using FixYa.

Where is the OBD port located in a toyota hiace 1998 with 1KZ engine and is it a OBD II?

It is OBD II all cars world-wide were required to be OBD II by the 1997 model year. The port should be located under the dash on the drivers side of the car. It looks like a serial port on the back of a home computer.

Why is the check engine soon light on? 94 toyota tercel. I took it to a parts store to have the code checked and they told us that we need to know where the port is. Does any one know where the diagnostics...

To give you a better jump in the direction of the repair, your vehicle's computer operates OBD I, your average auto parts store will only carry OBD II equipment. Your ALDP should be located on the drivers side under the dash near the door. This is the most typical location for it, however, not the only location. From time to time you may find on either side of the center console under the dash, closer to the firewall. Some vehicles even have a special port on the dash near the drivers door just for the link. You can buy a OBD I link that will attach and put the computer into diagnostic mode. Any such link should have a code guide as well. When you attach the jumper and turn the ignition on, the MIL (maintenance indicator light) will begin to flash. You will see breaks in the flashes to distinguish numbers. This will give you the readout of the trouble code. If the system tells you that the vehicle has an O2 sensor problem, simply replace the corresponding sensor. As OBD I only reads system failures and not variations in data, the computer will only trigger a MIL when a sensor fails. Hope this helps.
