Part 9: Model-Specific Notes for L302

• Valtra A Series (A75–A125): L302 is almost always the rail pressure sensor. The CP3 pump on these models is durable. Check the 5V reference circuit from ECU pin A27.
• Valtra N/T Series with AGCO Power 4.9L / 6.6L: Regulator failures are more common. The SCV valve (part no. 836714682) has a high failure rate after 4000 hours.
• Valtra S Series (S394, S416): Often L302 appears due to a clogged fuel cooler or air in the fuel cooler circuit. Check the return line cooler for blockage.
• Valtra G & Q Series (newer models): L302 may indicate a software glitch. Ensure your ECU is updated to the latest version (often solved with calibration update 43.11.xx).
