How to reset cel? PO115

[rweddy]

I just got done changing my timing belt, water pump, re-sealed oil pump, etc.

 

All went relatively smoothly.

 

Then when I refilled my coolant, I got some air trapped, and the car they a check engine light. Got the fluid all refilled and pulled the code.

 

PO115 coolant sensor.

 

So now how do I get this light to go off? Or did I fry the sensor?

Rich I assume you have a reader? Or maybe you just counted the flashes? My reader shuts off codes, but if you don't have that and are too far from an Autozone I would try just disconnecting the battery for a half hour and see if that works.

As for the cause of the CEL, my guess would be it got in the air pocket (the coolant sensor sits quite high on the engine block) and sent info to the ECU that was not in line with the other parameters. I would be surprised if it was fried.

I would be surprised if it hurt anything too. Do you think it will clear the code if you disconnect the battery Frag? I would think it would dump everything.

I use a scanner to clear the codes on my car (OBDII). Really dont know if disconnecting the battery will do same on an OBDII car. I would guess yes but am not sure. Josh should know about that.

Thanks Cookie, I ran to autozone to pull the code, they said they could reset it but might fry my computer?! I am hoping it will go away on its own, I will try to disconnect the battery and see if that works.

 

Thanks!

Naaa... Disconnect the battery, it seems to be smarter that your Autozone staff anyway.

Uh. That's a new one. The OBDII readers I've seen actually have a reset button on them.

I know, I saw the button and said can you press that for me?

My manger won't let me, unless you buy the new sensor then I can do it.

 

That is when I decided it was a good time to leave!

That was probably for the best. As others have said, disconnecting the battery for a while should clear the stored code(s). Unfortunately, that also usually means the computer will have to relearn your car's engine management systems and your driving habits. While its doing that, it runs in a default state. Just don't be surprised/concerned if things seem a little "funny" for a few miles.

Thanks for the heads up, I did this and drove a few miles and it turned off.
