Camshaft Position Sensor B Circuit Low Input (Bank 2)

on 2004 Ford Thunderbird 3.8L V6 · FWD

What this code means

The PCM reads an abnormally low voltage from the Bank 2 camshaft position sensor B. This suggests a short to ground or an open in the circuit.

Common causes

  • Short to ground in wiring
  • Faulty camshaft position sensor
  • Open sensor power or signal wire
  • Corroded connector

Diagnostic steps

  1. Scan and note freeze frame
  2. Backprobe sensor for signal voltage
  3. Check for short to ground in harness
  4. Replace sensor or repair wiring

⚠ STILL BEHIND THE PAYWALL
The 2004 Ford Thunderbird 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.
