Default OBD 2 port not working??

Just a quick one here.

Today i got a funny symbol appear on my dash. The best way i can describe it is a upside down Y which is being illuminated on the bottom right corner.

This appeared when i was cleaning out my throttle body aswell cleaning up throttle cable componets. I thought i was doing a decent job till i put it all back together and got that stupid light. Admittanly i did use some maintenance spray to free up the valve flap.

Now the problem is that i have used 3 scan tools and none work??

Could it be the OBD 2 port is garbage ie the wires could be screwd or the fuse is out? i know that the obd port shares its fuse with the 12v cigar lighter which is working? So surely the obd port should aswell?

Any help would be appreciated

If the error doesnt lights up the eml (engine symbol) light, then consult with the owners manual.

Obd only reads error codes that lights up the eml light.
For the rest, theres vol fcr

Depends on model year? Early 850s were not OBD compliant. You may need to make a flash code reader , look in the how to sections Jod did one on making one, dead easy and they work. Good luck.

As above, need to know the engine size, type and year.

MoT failure with this light on, so you need to read the codes, solve the problem and then clear the codes, which will switch the light off.

Also my car is a 1996 T5 Manual model.

I can see its says OBDII on the coin tray. So I am assuming its compliant? But none of the readers worked.

May have to take it into Volvo and get it removed

96’, not compliant even tho’ it has the port. You need to make the flash code reader as mentioned above.

Good luck.

Okay, you should really only use throttle body cleaner or carb cleaner...as you've just found out the hard way !! Sorry.
May have contaminated the oxygen sensor, it MAY clear itself after it been running a while, you could try disconnecting the battery for a couple of hours...

The car isn't OBD2, but I wouldn't take it to a dealer just yet. Make a flash code reader yourself as has been suggested - it's dead easy and dirt cheap. You'll be able to clear the fault code yourself. You'll certainly have more information with which to diagnose the fault. It's possible that it's nothing to do with the throttle body.

Basically the car's engine management system thinks that there's a fault, and it won't get better until it's told otherwise. It could be simple, it could be related to the throttle body cleaning, it could be a camshaft position sensor, or a knock sensor, or an exhaust emissions fault......or, or, or.......

The only way to know for sure is to read the codes. Luckily you don't anything more than a couple of paper clips, a length of bell wire and a bulb.
