Code P070, Intermittent Throttle Position (TP) Sensor Signal: Notes
WARNING: This page is about a different car, the 1995 Cadillac Eldorado. However, it is still accessible from the selected car via links, so may be relevant.
This test monitors MAP and TP sensors. Code P070 will set if MAP value remains constant and TP sensor value changes considerably. Engine operation requires that any large change in TP sensor value must be followed by a change in MAP sensor value.
