Code p1120 on a 2001 mustang base model - 2001 Ford Mustang
A P1120 means a throttle position (TP) sensor out of range. It could be TP circuit with frayed wires, corrosion on TP circuit connectors, or TP sensor loose pins. If you are not knowledgable in this area, I highly recommend that a knowledgable mechanic deal with this issue and may recommend a replacement.
