Hello everyone,

Hope everyone is well in these absurd times.

My friend brought over her 2007 s40 to replace the coolant hoses (leaking) and figure out why her car is in limp mode.

It sat for two days (raining) and now I can't get the damn thing started. I put the battery on a charger overnight, VIDA shows it at 12.1V (Is this battery shot?), it turns over revs up and then shuts down.

Did I screw something up when I disconnected the computers on the airbox (I hate this design)?

VIDA print outs:

ECM-1300 MAF Sensor - Signal too low
ECM-1400 Manifold Pressure Sensor - Signal too high
ECM-140B Manifold Pressure Sensor - Signal too high
ECM-914C Throttle Valve - Signal too low
ECM-130B MAF Sensor- Signal too low


I've got the car until Monday, a used but working MAF sensor should be here by the 4th just in case.

ANY idea whatsoever would be greatly appreciated!
