P104C – High Voltage in Reductant Level Sensor Circuit 2

Explanation of Code P104C: “Reductant Level Sensor (AdBlue) Circuit – Voltage Too High”

Severity

Level: 🟠 Moderate (risk of reduced anti-pollution performance and failing technical inspection).
Urgency:
Reduced power activated (limp mode).
Exceeding emission limits (high NOx).

Common Symptoms

🚨 Check engine light on (MIL) and/or flashing SCR/AdBlue light.
🐌 Reduced power (“Limited starts remaining” message).
💡 Dashboard warning (e.g., “Low AdBlue level” even when tank is full).

Main Causes

Faulty reductant level sensor:

Sensor giving incorrect reading (phantom high voltage).

Electrical issues:

Short to ground in the sensor wiring harness.
Connector corrosion (moisture or AdBlue leak).

PCM failure (rare):

Signal processing error or outdated software.

Diagnostic Procedure (Detailed Steps)

Step 1: Visual Inspection

Locate the sensor: Integrated into the AdBlue tank (e.g., Mercedes Sprinter, Peugeot 508).
Check for AdBlue leaks: Bluish corrosion around the connector.

Step 2: Sensor Electrical Test

Multimeter:
Power supply: 5V between the power terminal (red wire) and ground.
Signal: 0.5-4.5V depending on AdBlue level (empty → 0.5V, full → 4.5V).
If voltage > 4.8V → Short to ground or faulty sensor.

Step 3: PCM Circuit Check

Continuity: Test wires between the sensor and PCM.
Insulation resistance: No contact between signal and ground.

Solutions & Costs

Problem	Solution	Average Cost
Faulty level sensor	Replacement	€150 – €400
Wiring repair	Harness/connector repair	€50 – €200
Connector cleaning	Contact spray + dielectric grease	€20 – €50
PCM reprogramming	Software update	€100 – €300

Mistakes to Avoid

❌ Handling AdBlue without protection: Corrosive liquid (wear gloves/goggles).
❌ Ignoring AdBlue leaks: Can damage the sensor and tank.

Frequently Affected Models

Mercedes-Benz Sprinter (2016-2022): Recurring sensor issues.
Peugeot 508 (BlueHDi 180): Corroded connector.
Volvo FH/FM (Euro 6): SCR system failures.

Practical Case

Problem: Code P104C on a Mercedes Sprinter 2019 with “Insufficient AdBlue” message.
Diagnosis: Level sensor stuck in high position (voltage at 5V).
Solution: Sensor replacement (€320) + tank cleaning.

Pro Tips

Reset the AdBlue system: After replacement, use a Star Diagnostic tool (Mercedes) or DiagBox (Peugeot).
Use certified AdBlue: Avoid counterfeits to prevent deposits.

If the code persists after repair, consult a professional equipped with manufacturer diagnostic tools (e.g., Star Diagnostic or DiagBox)! 🔧🚗🔋
