To have so many different codes at the same time indicates that the first place to start looking is the wiring harness itself. Locate the MAP (manifold air pressure sensor - code 31) and IAT (inlet air temperature sensor - code 24) connections. Disconnect and reconnect each sensor a few times and check that the connecting socket and pins are clean and free of corrosion - the codes indicate intermittent breaks. Check all fuses are clean and well mounted. Examine wiring harness for chafing, abrasion and signs of wear. Any intervening connections between the wiring harness and electronic control unit (ECU) need to be checked over and should be free of oily grime.

yes all brake boosters have to have a vacuum line

CODE 32- FRONT LEFT WHEEL SPEED SENSOR SIGNAL MALFUNCTION. CODE 31- FRONT RIGHT WHEEL SPEED SENSOR SIGNAL MALFUNCTION. CODE 48- OPEN OR SHORT CIRCUIT IN VTA2 SIGNAL CIRCUIT OF THE SUB THROTTLE POSITION SENSOR.

Try Using the last 4 numbers of your chassis number
