Re: Trouble code 45

Found some info on another site for you - The MAP sensor or pressure sensor is a little black sensor right next to the boost solenoid that receives a boost reference from the inlet manifold via its vac hose connection. The sensor is also wired to the ECU, so that the ECU knows what the boost is at any point in time. The MAP sensors are rated at a max level of absolute boost, so when they fail, could lead to overboosting, as it won't be able to tell the ECU when boost cut has been breached, etc...

Very important - replace it!

You could try a good breaker like Grade A - Untitled

If it was me I wouldn't be driving it mate until you get sorted

Re: Trouble code 45

Boost gauge is sitting fine and is connected direct to the manifold so no overboosting going on. i have tried grade a and they gave me a much friendlier price thanks
