Peugeot 301 Gives Error Code P1166

The tool was made with software + downpipe and gave this error code when I compress it after 2-3. I would be glad if you can illuminate it thanks

my brother got a quote from a source probably as a warning about fuel .... Error code P1166 After the sales definition of the fault code High pressure fuel regulation: Rail pressure measured higher than maximum pressure Correction priority 3 Diagnosis definition Diagnostic pressure higher than maximum pressure: 5 seconds Throughout the 1750 bar Diagnostics activation conditions For Pcode transmission conditions, see relevant contents. Conditions for the elimination of the fault 5 minutes driving Sub-stepped modes if there is a fault Switching off the engine Irreversible disconnection of the cruise control Disabling automatic mode for the electronic parking brake Disabling the speed limiter Disabling the warning light and / or warning message Lamp MIL Symptoms (Possible customer complaints) Power Lack of Jerking / Suspected areas Lack of electrical wiring Connectors High pressure pump Engine ECU Diesel fuel high pressure sensor

I am considering removing and cleaning the fuel pressure sensor. Thanks in the meantime

I hope the problem is solved
