intermittent code 45 on boost

carlck19 · 11-15-2012, 12:47 PM

Hi guys I thought I was getting robs knock light but I believe it to be an intermittent code 45 that comes on when i get on the throttle. I checked the past codes with the black connectors and this is the only one that came up. how should i go about fixing this/should i even worry about it?

it is either your boost sensor or the solenoid right next to it, which switches the sensor from reading manifold pressure to atmospheric. check the vacuum lines for cracks too
