Hello, I am new to jeep forum. Cool place to read and learn. I have a jeep grand cherokee 2001. Had engine light on so I checked codes with key and there were 2 codes. AC Clutch and EVap. Repaired both and engine light went off. But why are the codes still showing in dash when I check with key. Is there a way to clear or is there still a problem? I want to smog this jeep?

Any help is appreciated. Thanks!

 

Welcome to CF!

An OBDII scan tool will clear the codes. Find someone who will do this or rent a tool. Most mechanics or Auto Zone will read the codes, but are not allowed to clear the codes without having done the work. I bought one myself for about $87. Mine is an Actron CP9575 and was on sale at Advance Auto. I figure owning a Jeep, I'm going to need one anyway.

I have a recurring P0740 code which is Torque Converter Solenoid and comes up about once a month. I'm not about to tear into the transmission just to fix this yet, so I just clear the code when I need to. I'm only loosing a little fuel mileage on high speed trips which I don't do much of anyway.

 

That was really helpful. I do know someone too. Thank You! Dave

 

That's why I'm here. Always glad to help when I can.

 

This process will clear the codes. It works.

 

Wow! No kidding It really did work. It sure saves having to purchase OBD Tool or pay someone to do it. Thank you everyone for your valuable information.

 

It sounded to good to be true to me also. But then i figured what the hell. Your welcome.
