199003071 - P0235 Boost pressure sensor

This error is detected if there is a short circuit to the positive or break (with short circuit to +Vbatt. / open circuit detail) or a short circuit to earth (with short circuit to earth detail) in the circuit connected to Pin 7 of the junction unit. As a result the maximum power is reduced and the exhaust gas recirculation valve is switched off. In addition, if there is a short circuit, the supercharging pressure can no longer be controlled.
