OBDII reader problem (not reading)

[Noname]

I just replaced the Obd2 port with a new one and connected my reader but it’s still saying “linking error”? I checked with my multimeter pin 6 and pin 4 and Im getting 12.3volts. Is that the range i should be getting to get power there?


Trying to figure out if it’s the Obd2 reader itself all along now….

It sounds like you're on the right track by checking the voltage at pins 16 and 4. Generally, you should see around 12 volts or so when the vehicle is in the "On" position. Sounds like you're fine as far as the power goes.

A few things you might want to check:

OBDII Reader Compatibility: Make sure that your OBDII reader is compatible with your vehicle. Some readers may not work with certain makes or models.

Connection Issues: Double-check the connections to the new OBDII port and make sure everything is seated properly. Loose or corroded connections could cause linking errors.

Ground Connection: Ensure that your OBDII reader is able to establish a good ground. You might want to check pin 5 (ground) to ensure that it’s properly connected.

Try Another Reader: If possible, try a different OBDII reader to see if the problem persists. This will help determine whether the issue is with the reader or the vehicle's OBDII system.

Vehicle Issues: There may be underlying issues in the vehicle’s ECU that are causing the reader to fail to link as well.

It was working the last time I checked I used the same reader for many years, even when I changed out the pcm a few years back I remember it working then too. Maybe the reader is shot or something.

Starting to wonder about if the pcm has a software issue with the p0153 code Im getting.

Is there a way to check with a multimeter to the pin on the computer for bank 2 sensor 1 to see if there’s voltage there?
