I have a 2005 MCS I got it for my daughter to learn to drive on a stick shift, secretly I always wanted one so I dive it often. . I was driving on the highway and the car just all of a sudden it lost almost all power. It takes forever for the rpms to rise, and it has zero power it's like the supercharger isn't spinning but it is. I just can't tell if its the pulley or the bypass valve is not closing fully.

I got the codes off the ecu.
p1688
p0341
p0108

Thanks in advance,
Sean

 

Is It in limp home mode?

 

I don't think so, how can you tell?

 

You'd know, it wouldn't RPM at all under throttle of any kind.

The codes are:
P0108 Manifold Absolute Pressure/Barometric Pressure Circuit High Input
P0341 Crankshaft Position Sensor 'A' Circuit Range/Performance (Bank 1 or Single Sensor)
P1688 Electronic Throttle Control Monitor Level 2/3 Air Mass Flow Calculation Error

I'm thinking Crank Pulley, if it's the stock one and the car has over 75k, it's a good bet.

 

Thanks I'll check that. I hope to get to it before the weekend.
