P2263 Fault in Fuso Canter: Causes and Fixes When Climbing Steep Hills

Model: Fuso Canter Fault Code: P2263 Posted: 2020-04-23 04:15

Hi everyone, I'm experiencing a P2263 diagnostic code on my Fuso Canter, which triggers an orange engine warning light specifically when driving up steep inclines. After clearing the fault by removing certain fuses and replacing components, the issue does not reappear under normal conditions—only returning when climbing a steep hill again. I've already tried using both a turbocharger cleaner and an EGR cleaner as initial troubleshooting steps, but the problem persists. Does anyone have experience with this specific P2263 fault on Fuso Canter models? What was the root cause or solution you found? Any insights would be greatly appreciated. Thanks in advance, Ben
