P06D5Sensor Reference Voltage E Circuit Range/Performance
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- The engine module feeds sensors from several regulated 5 V reference circuits; a short at one sensor pulls the whole circuit down and all its sensors report at once – unplug them one by one to find the culprit. P06D5 is the range/performance check of reference circuit E. No manufacturer document available to us uses this code; the description follows the other reference circuits. Ford checks circuits A–C this way (below 4.7 V or above 5.2 V, 0.5 s).
- What you may notice
- Check engine light
- Several sensor codes at once
- Reduced power or limp mode
- Possibly starting problems
- Likely causes
- LikelyShort in the wire or sensor of a connected sensor
- PossibleChafing or water in harness or connector
- PossibleA connected sensor faulty internally
- RareModule internal voltage regulator or components
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
