Causes

Open or short in sensor reference/supply wiring (group 3)
Poor or corroded connector(s) at sensor(s) or ECU
Failed sensor(s) drawing excessive current or open circuit
Faulty ECU/power-supply driver or internal ECU connector fault
Intermittent wiring damage from chafing, heat, or pinched harness
Low battery/weak charging system affecting reference voltage

Symptoms

Malfunction Indicator Lamp (MIL) illuminated
Related sensor(s) reporting implausible or out-of-range values in live data
Engine may run poorly, stumble, or go into limp mode depending on which sensors are affected
Intermittent faults that may change with vibration, temperature, or engine load
Multiple sensor-related codes referencing the same supply/voltage rail

What to check

Read and record all stored codes and freeze-frame data with a diagnostic scanner
Inspect wiring harness and connectors for sensor group 3 for damage, corrosion, or loose pins
Backprobe sensor connector(s) and measure reference/supply voltage with ignition ON (engine off) and compare to expected value
Monitor live data for the affected sensors while cranking/running to see noise, dropouts, or constant values
Wiggle test harness while monitoring voltage/live data to reproduce intermittent faults
Check battery voltage and charging system to ensure stable supply (12–14.5 V)

Signal parameters

Typical reference/supply voltage: ~5.0 V (±0.25 V) at sensor connector with ignition ON
Battery voltage: 12.0–14.5 V (engine running and charging)
Short-to-ground indication: supply voltage near 0 V under load or when engine cranks
Open-circuit indication: no reference voltage present at sensor connector
Expected continuity: low resistance (

Diagnostic algorithm

Connect a scan tool, read DF013 and any related codes. Record freeze-frame and live data for affected sensors. 2) Visually inspect sensor(s), connectors and harness for physical damage, corrosion or water ingress. Repair visible damage. 3) With ignition ON (engine off), backprobe the sensor reference/supply pin and verify ~5 V present. If voltage missing or incorrect, proceed. 4) Check battery/charging voltage; if low, charge/test battery and charging system, then retest. 5) If reference voltage absent or unstable, isolate harness: disconnect the sensor plug and measure supply at ECU side of harness. If supply present at ECU but not at sensor plug, repair harness/connector. 6) Check continuity and for shorts between supply and ground/battery using multimeter (power off). Repair any short or open. 7) If wiring and connectors are good and supply out on ECU side is incorrect, perform ECU power/ground checks and consult manufacturer procedures; consider ECU repair or replacement only after confirming external wiring and sensors are functional. 8) After repairs, clear codes and verify the fault does not return and that sensor live data is within expected ranges.

Likely causes

Damaged/crimped connector at sensor 3 or its harness splice
Wire shorted to ground or battery in sensor supply circuit
Corroded pins in ECU connector or sensor plug
Failed sensor that has shorted internal electronics
ECU internal reference-voltage regulator or driver fault

Fault status

⚠️ Status

DF013 -> P0697: Sensor reference/supply voltage circuit fault for sensor group 3 detected (open/short/voltage out-of-range). Verify wiring, connectors, sensors, and ECU supply.
