Engine/Transmission (1998.5 - 2002) Smarty, setting codes

[timbo]

Does the smarty set off the check engine light when its cold out?

 

[JKinney]

To my knowledge no. Since your light is on what codes have been set?

 

[C4gan]

I've had mine for 2 winters and no C/E light.

It sets a P0602 (ECM fueling calibration error,normal with nonstock software) and a p1693 (DTC detected in companion JTEC module).

those are normal codes to have due to you having an edge comp and smarty. anytime a code is present in the ecm it will show up in pcm. Those two will always be there.

Never had the Smarty set a code due to ambient temperature.



At first my Smarty would set the CEL due to p0602. That was due to my truck having California Emissions ECM software. I sent it back to Bob W and I assume he re-programmed it to fix that problem.

Bob would have to speak up, but I think we all get 602 the info is posted in the smarty thread.

I get 602 without a CEL.
