DTC Set Conditions
WARNING: This page is about a different car, the 2005 Dodge Stratus and 2005 Chrysler Sebring. However, it is still accessible from the selected car via links, so may be relevant.
If the TP sensor output voltage is less than 0.2 volt when the engine is not at idle, the output is judged to be too low and DTC 12 is set.
