Hi guys,
After I installed a camshaft 221/221/558/558/112 + hp tuner on my car I get the traction control light and engin light on with this code P0121.
How to solve this problem with hp tuner
thanks in advance

search p0121 on here and there are several helpful threads


i have this issue on my truck and have been slowly working on it

 

i changed the tb , but still im getting the same code, and i tried to disable the code but it didnt help.
i dont know what to do but some of my freinds saying to set "p0121 error max map" to 100kPa and set "p0121 error min map" to 0kPa in order to dissable the test for p0121 in the hp tuner.what do you think about that?

 

i found it
set "p0121 error max map" to 100kPa and set "p0121 error min map" to 0kPa in order to dissable the test for p0121.
