P1020 Código de avería diagnóstico (8 interpretaciones)

The control module detected that the current in the WT overload protection, control motor circuit was above the expected range. This is the manufacturer-specific definition used by BMW.

The control module determined that the Valve position control circuit - valve did not change state as commanded and appears stuck. This is the manufacturer-specific definition used by Honda.

The control module detected a fault associated with the Valvetronic Eccentric Shaft Sensor Power Supply circuit or function; the stored code identifies the affected component rather than a single failure mode. This is the manufacturer-specific definition used by MINI.

The control module detected a fault associated with the MIVEC Performance Problem Bank 1 circuit or function; the stored code identifies the affected component rather than a single failure mode. This is the manufacturer-specific definition used by Mitsubishi.

The control module detected that the Variable valve lift position sensor 5V supply fault was above its expected limit. Documented for the Bosch MED 17.4.x engine ECU (EP6 THP family) on Peugeot applications; the same PSA control units are also fitted to Citroën models.

The control module detected that the Power supply fault in the eccentric sensor of the variable valve lift system was above its expected limit. Documented for the Bosch MEV17.4 engine ECU (EP6 1.6 VTi) on Peugeot applications; the same PSA control units are also fitted to Citroën models.

The control module detected that the monitored Fuel pressure - control limit value exceeded the calibrated threshold. This is the manufacturer-specific definition used by Audi.

The control module detected that the monitored Fuel Pressure Regulation: Control Range value exceeded the calibrated threshold. This is the manufacturer-specific definition used by Volkswagen. Volkswagen Group tools also report it as fault code 17428. Documented across Volkswagen Group applications (Audi, SEAT and Škoda included).
