Pcm Code P070 - Intermittent TP Sensor Signal: Action

None.

NOTE: Test number refers to number on diagnostic chart. Reference to CHART 3 refers to POWERTRAIN CHARTS.

Checking PCM Code P070 snapshot value is used to determine if an intermittent low or high voltage caused code to set. An intermittent low voltage can be caused by an open or short to ground in circuit No. 417, an open in circuit No. 474 or a faulty TP sensor. An intermittent high voltage can be caused by an open in circuit No. 1076 or a short to voltage on circuit No. 417.
