21390067 Pressure Sensor | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta SCR / Diesel Exhaust Fluid Pressure Sensor - Part Number: 21390067

Pressure sensor used in the Selective Catalytic Reduction pump and dosing circuit on specified Volvo Penta TAD1360-TAD1362VE industrial engines. It reports diesel-exhaust-fluid pressure to the aftertreatment controller so the pump can prime, regulate pressure and deliver the commanded quantity of urea solution to the dosing valve.

⚙️ Key Features

• Genuine Volvo Penta SCR / DEF pump pressure sensor

• Monitors dosing-circuit pressure for closed-loop pump control

• Supports correct priming, pressure regulation and urea delivery

• Widely cross-referenced to Bosch and recognised aftermarket sensor numbers

• Critical emissions-system sensor that can trigger warnings or derate when faulty

🚤 Compatibility

Commonly used on:

• Volvo Penta SCR aftertreatment and diesel-exhaust-fluid pump systems

Typically suits:

• Engine models:

• TAD1360VE

• TAD1361VE

• TAD1362VE

• HP Range: Engine-rating dependent; sensor fitment is controlled by the SCR system and engine serial number

• Engine Type: Volvo Penta TAD13VE inline six-cylinder industrial diesel with SCR aftertreatment

• Year Range: Emissions-system and serial controlled; confirm the pump-unit configuration before ordering

🔌 Function

Measures pressure in the diesel-exhaust-fluid pump and dosing circuit. The control unit uses this feedback to verify system priming, regulate pump output, detect leaks or blockages and confirm that adequate dosing pressure is available.

Common signs of failure:

• SCR pressure or dosing-system fault codes

• Pump runs continuously, fails to prime or shuts down prematurely

• Low, high or implausible DEF pressure readings

• Incorrect or inhibited urea dosing

• Emissions warning, engine power derate or aftertreatment shutdown

📦 Condition

• Genuine Volvo Penta part

• Brand new

• Supplied in original or equivalent packaging
