P1171 Code défaut de diagnostic (13 interprétations)

The control module detected improper operation of the Knock sensor(s) (KS) circuit. This is the manufacturer-specific definition used by BMW.

The control module detected a fault associated with the Fuel system - lean during acceleration circuit or function; the stored code identifies the affected component rather than a single failure mode. This is the manufacturer-specific definition used by Chevrolet.

The control module detected a fault associated with the Fuel System Lean During Acceleration circuit or function; the stored code identifies the affected component rather than a single failure mode. This is the manufacturer-specific definition used by Chrysler.

The control module registered the fault condition described as "Rotor Sensor Fault". This is the manufacturer-specific definition used by Ford.

The control module detected improper operation of the Heated oxygen sensor (HO2S) 1 circuit. This is the manufacturer-specific definition used by Honda.

The control module detected improper operation of the Electronic throttle system (ETS), WOT. This is the manufacturer-specific definition used by Kia.
