What is it? Without buying anything preferably. I've heard you can pull a certain fuse and that will reset it? Is that true?

 

disconnect the battery for about 10 seconds.

Question is, have you identified why your CEL is on in the first place?

 

Disconnecting the battery works, but if you haven't fixed the problem that was causing the CEL to come on it will pop up again after it passes the "pending code" status.

Before disconnecting the battery make sure your key fob is working...after disconnectint the battery the alarm will go off at random for no reason until the car is locked with keyfob...did this on me after replacing a battery LOL at midnight and 3 am ..neighbors we're less than enthusiastic LOL

 

I use the Torque app for Android and a Bluetooth dongle.
Read codes and clear CELs. and monitor your card OBD system.

 

Is that available for iPhone? I asked my local pep boys about it the other day. Guy was clueless.

 

Idk if there is a Bluetooth version for iPhone yet.
There was a more expensive setup called the REV app, but I think it has to be plugged into the OBD with wires.

 

Get the ELM-327 bluetooth dongle off of eBay. They run for about $7-$8 and will connect with tons of free apps on Android and iPhone (Piston, DashCommand, ect.). You can clear your CEL and see live data in no time at all.

 

Thanks for the heads up.
I wasn't aware the iPhone had a Bluetooth compatible app.

 

Thanks I'll be ordering this asap

 

It's no Cobb, but it does the job.
