I am new to the forum. I got a chk engine sign today, so I went to autozone to chk it out. The code was P1136. Which is fan circuit malfunction. what exactly is this? Does this need urgent attention (can i live with this). If not how much I'll be spending?

 

P1136 means "Fuel trim too rich at idle".

 

what is that suppose to mean? what can i do to fix it?

 

Actually P1136 is system too lean, not too rich.

Check for vacuum hose leak, intake leak. Failing that may need Mass flow sensor (MAF).

Could also be clogged injectors. Run some fuel injector cleaner and look for vacuum leak. If niether help, replace the MAF.

search the archives.

 

P1137 is too lean , P1136 is too rich.

Could be oxygen sensor.
