The existing wiring harness for the Diesel Particulate Filter (DPF) differential pressure sensor can fail on certain 236D, 242D, 246D, 262D Skid Steer Loaders, 257D, 277D, 287D Multi Terrain Loaders, and 259D, 279D, 289D Compact Track Loaders, equipped with a HRC C3.3B engine. The existing mounting for the DPF differential pressure sensor can have excessive vibration causing wires in the engine harness to fail. This can lead to various fault codes: 3251-3, 3251-4, 523602-0 and frequent regen cycles. A new support bracket for the sensor needs to be installed. |
