Overview
The Volvo Penta 24778541 is a genuine OEM rudder angle sensor for the DPI sterndrive steering system. It monitors the actual steering position of the drive and feeds that information back to the Volvo Penta EVC (Electronic Vessel Control) system, enabling accurate electronic steering and real-time drive-position data. Volvo Penta DPI maintenance documentation identifies 24778541 as the improved replacement for the earlier 23538661 sensor.
Compatible Applications
- Volvo Penta DPI Sterndrive
- Volvo Penta DPI-A Sterndrive
- Installations paired with D4 engines using EVC 2.0 electronic controls
- Installations paired with D6 engines using EVC 2.0 electronic controls
Fitment is specific to the DPI steering-position system. Confirm your exact drive model and serial number before ordering. Do not substitute for engine temperature, pressure, speed, or trim sensors.

Technical FAQ
Q: Is 23538661 the same as 24778541?

Q: How do I know if this sensor fits my DPI drive?
A: Confirm your drive model (DPI or DPI-A) and serial number, and cross-reference with the applicable Volvo Penta parts diagram for your steering assembly.
Q: What are signs this sensor needs replacement?
A: Inaccurate or intermittent rudder-position readings, steering-related fault codes in the EVC system, or a sensor confirmed defective through diagnostic testing. Also inspect electrical connectors and the DPI wiring harness — connection issues can produce similar symptoms.
Q: Does installation require calibration?
A: Yes. Follow the applicable Volvo Penta DPI service procedure for installation and verify correct sensor feedback through the EVC system before returning the vessel to service.
Parts Desk Insights
This is a critical component in the DPI steering-feedback circuit — it's what tells the electronic control system where the drive is actually pointed. When it fails, customers typically see steering faults or erratic position readings in the EVC display. It's worth checking the wiring harness and connectors at the same time, since intermittent connection problems can mimic a failed sensor. Matching by serial number and confirming against the DPI diagram is essential here — the DPI system has specific sensor configurations that vary by production range.
