Volvo Penta DEF / Urea Level Sensor 24669596 | Replaces 22969244

Volvo Penta DEF / Urea Level Sensor 24669596

• Part Number: 24669596
• Brand: Volvo Penta
• Official Product Type: DEF / Urea Tank Level Sensor
• Supersedes: 22969244 (confirmed Volvo Penta supersession)
• Replaced By: No further confirmed supersession — 24669596 is current
• System: SCR exhaust aftertreatment / DEF (diesel exhaust fluid) level monitoring
• Tank Application: 25 L DEF / urea tank (as documented for superseded 22969244)

What This Part Does

The Volvo Penta 24669596 is a genuine OEM level sensor for the DEF (diesel exhaust fluid / urea) tank in selected Volvo Penta SCR exhaust aftertreatment systems. It monitors fluid level in the DEF tank and reports to the engine control system to ensure SCR operation and emissions compliance. This part directly supersedes the earlier 22969244, which is documented in Volvo Penta SCR parts diagrams as the level sensor for a 25 L DEF/urea tank.

This is a specific SCR system component — it is not a general engine sensor and should not be selected by appearance or proximity to other sensor part numbers in the Volvo Penta catalog.

Compatible Applications

• Volvo Penta TAD1170VE engines equipped with SCR / DEF system
• Volvo Penta TAD1171VE engines equipped with SCR / DEF system
• Volvo Penta TAD1172VE engines equipped with SCR / DEF system
• Selected TAD840 / TAD850 / TAD870 / TAD880-series engines with SCR/DEF systems
• Other Volvo Penta SCR applications where the parts diagram or serial-number lookup specifies 22969244 or 24669596

Confirm the following before ordering:

• Engine model and serial number
• SCR / DEF system configuration
• DEF tank capacity
• Existing sensor part number
• Connector and harness configuration

Superseded Part Number

Confirmed Volvo Penta supersession: 22969244 → 24669596.

The earlier 22969244 is documented in Volvo Penta SCR parts diagrams as the level sensor for the 25 L DEF/urea tank. The current service replacement is 24669596.

When to Replace This Sensor

• DEF level readings are incorrect or erratic on the display
• SCR system reports a level-sensor fault code
• Sensor connector or housing is visibly damaged
• Corrosion or DEF contamination has affected the electrical connection
• Volvo Penta diagnostic procedure confirms sensor failure

Before replacing the sensor, inspect the wiring harness, connector pins, and grounds to rule out faults outside the sensor itself.

Installation Notes

• Isolate electrical power per Volvo Penta service procedure before removal
• Keep all tools and components clean — DEF systems are sensitive to contamination
• Inspect connector pins and harness condition before installing the new sensor
• Confirm the replacement carries part number 24669596
• Install with correct sealing components per Volvo Penta service procedure
• Clear SCR fault codes and verify DEF level indication after installation

Technical FAQ

Is 24669596 a direct drop-in for 22969244?
Yes — 24669596 is the confirmed Volvo Penta supersession for 22969244. Use 24669596 as the current service replacement wherever 22969244 is specified.

Which DEF tank size does this sensor fit?
The superseded 22969244 is documented for the 25 L DEF/urea tank in Volvo Penta SCR systems. Confirm tank size and system configuration by engine serial number before ordering.

Is this the same as the other sensors in the 24669584–24669596 range?
No. The 246695xx range includes several different sensor types. 24669596 is specifically a DEF/urea level sensor for the SCR aftertreatment system — it is not a general engine management sensor like 24669584 or 24669592.

Can DEF contamination damage the sensor?
Yes. DEF is corrosive to many metals and can damage connectors and sensor components if the system is serviced without proper precautions. Always keep the tank, fittings, and sensor area clean during service and use only approved DEF handling equipment.

Parts Desk Insights

This is one of the few sensors in the 246695xx range where the application can be confirmed with confidence: 24669596 is a DEF/urea tank level sensor for the Volvo Penta SCR aftertreatment system, not a general engine sensor. The most common issue is customers unfamiliar with SCR systems ordering a nearby sensor number without recognizing the DEF-specific application. If a machine is showing SCR faults alongside an incorrect DEF level reading, this sensor is the right starting point — but always confirm the wiring and connector before condemning the sensor itself, as DEF fluid ingress into connectors is a frequent cause of false fault codes.
