Torque Converter Clutch Inductive Signature Malfunction

on 2011 Ford Explorer 3.5L V6 · AWD

What this code means

The TCC solenoid did not move when the PCM commanded it. This is an information code — there should be a more specific code stored in the Transmission Control Module. The TCC solenoid circuit performance is not as expected.

Symptoms

  • Check Engine Light
  • TCC not engaging
  • Reduced fuel economy on highway
  • Transmission overheating at highway speeds

Common causes

  • Faulty TCC solenoid
  • Wiring issue to TCC solenoid
  • Low transmission fluid
  • Internal transmission blockage
  • Contaminated transmission fluid

Diagnostic steps

  1. Check for additional transmission DTCs in TCM
  2. Test TCC solenoid resistance
  3. Inspect TCC solenoid wiring
  4. Check transmission fluid level and condition

Repair notes

Check for companion DTCs. Replace TCC solenoid if faulty. Service transmission fluid.

⚠ STILL BEHIND THE PAYWALL
The 2011 Ford Explorer repair data is incomplete because no one has sponsored it yet. For $99, we generate the full step-by-step procedures, then fact-check them with a second AI pass and your expert review. Your name on every procedure, permanently.
The same data would cost $169/mo from Mitchell1 or $30/year from ALLDATAdiy — and you'd be renting access, not freeing it. Sponsor once, free forever.
