My OBDII scanner will not read any info,how can I check proper connection to OBD plug in my Ford Explorer 2000?, 'check engin' light at start-up, never comes 'ON'-I tried to read through the OBD but the scanner does not read anything at all.

Hook up a scan tool and read the DTCs. The P-Code number tells you the problem and the fix.

1. Throttle control problems: A sticky throttle control or a malfunctioning throttle position sensor could be causing the high revs.
2. Ignition system issues: A faulty ignition module or spark plugs could cause the engine to run rich, causing high revs.
3. Vacuum leaks: A vacuum leak can cause the engine to run lean, leading to high revs. Check for any visible leaks in the vacuum lines and hoses.
4. Fuel system problems: A clogged fuel filter, a failing fuel pump, or a malfunctioning fuel pressure regulator could cause high revs.
5. EGR valve: A clogged or sticking EGR valve could cause the engine to rev high.

It's recommended to have a professional mechanic diagnose the issue using an OBD-II scanner to retrieve the error codes and perform a proper diagnosis. Based on the error codes and the symptoms, they can determine the root cause of the problem and recommend the necessary repairs.

How old is the car? Before 1996 cars used the older OBD not OBD2. Some modern scanners can't or don't read this type of code. If it is an older car you might have to use a scanner designed for the older OBD codes.
The connection port is under the dashboard near the bonnet release lever, (See photo). Turn everything off. Make sure the plug is pushed well into position. The scanner should start up on its own. Turn on the ignition. The scanner should connect to the cars OBD system.

Unless a code has been set the light usually comes on with the key set to run with the engine off. Suggest going to your friendly auto parts dealer and have them connect a OBDII scanner and check for codes. This service is usually complementary!

Some codes (Catalytic converter) can represent a significant expense but not interfere with the driving performance.

fuse number 24 is a 30 amp fuse goes to pcm relay and fuse number 30 the 30 amp fuse to ignition to pcm power diode.if check light is working your pcm has power but you could have short in the dlc connector terminal where you scanner adapter goes.your scanner suppose power up from the dlc terminal for obd 2 system the obd 1 you connect to cigarette light or use battery hook up cables that come with scanner make sure you are using correct adapter.

their isnt one on pre 1995 vehicles

The connector is located on the drivers side just above the parking brake pedal.

Hope this helps.

just bring it to a local advance auto or auto zone they will hook up a code reader this will point you in the right direction it may be an O2 sensor MAF sensor in need of a tune up (plugs, wires, PCV, Air cleaner etc.)

Most consumer available scanners read OBDII on 96 or newer vehicles. If your car does in fact have a OBDII plug then all you need is the software in your scanner to be able to read OBDI codes...a 95 is running OBDI. Advance Auto or Autozone might have a OBDI compliant scanner for free...just tell them you have the OBDII port so they don't take up all your time digging for the adapter!

This vehicle has the OBDII system and you can only retrieve codes on this with a scan tool. Some of your parts houses like Autozone will retieve them for you for free.
