Idling High when placed in Park

[alex61089]

So i had a problem with the TPS and i Fixed it. My HICAS light came on once but after i turned the car off and on again it went off and never came back on. But when i Have my car idling in park my RPMS are around 800 ( my TPS is set to (0.45). I took the J out for a spin to test the shifting and i hit about 80MPH When i pulled back up in front of my house and put it in park BAM! I had an RPM of almost 2000. I turned the car off and back on again and the RPM stayed at 800. Paul said it could be that i need the self learning codes erased but i dont know because i've never had this problem before. And i did unplug the TPS when the engine was on to erase the old settings... So... anyone have an idea of whats up?

Trust me or wait till Q45tech comes in to confirm what I said, But either way you need to reset the ECU some how.

You could try some of the methods listed here and see if they work:http://x.nissanhelp.com/forums....html
