P07C5 Intermediate Shaft Speed Sensor A Circuit Low

Check engine lightOn
EmissionsRelevant
Drive cycleNot required
Limp modePossible

These low/high codes are a purely electrical check of the sensor's signal voltage at the module and run even with the vehicle at rest – unlike the circuit, range, no-signal and intermittent codes, which evaluate speed while driving. Low means a short to ground, high a short to supply or, depending on the circuit, an open. An intermediate shaft sensor sits on a countershaft or planetary element between input and output (Ford 5R110W, reported under P0791). No manufacturer document available to us uses this code: GM runs exactly this check on its ring gear speed sensor of the 9- and 10-speeds under its own code P176C (below 0.25 V, 0.25 s, one trip).

Likely causes

Signal or supply wire shorted to ground (chafing at the case)
Sensor shorted internally
Oil or moisture in the connector
Module input faulty

Symptoms

  • Check engine light (GM after one trip)
  • Limp mode, harsh shifts, no converter lock-up
  • Adaption frozen
