CHECK ENGINE lamp comes on, difficult on cold startsConditions
Voltage less then 0.03 volt or greater then 4.96 volts or abnormal rises in temperature after starting in relation to the programmed model that can be found in the control module's permanent memory.Note | ||
If there is a decline in function the control module chooses a pre-programmed value corresponding to 80°C (176°F), which means the car can be difficult to start when the engine is cold due to the fuel/air mixture being too lean. |
