[drice]

last night headed down road truck lost power for a sec then came back did alright for about 1/2 mile then started jumping check engine light came on so pulled over ran power pup to see what it was. low boost was the answer. now does anyone know what are the possible causes of this?

I had trouble with the connection on the sensor in the air intake. It will cause the problems you described.

I was gettin low boost code as well a few months ago. Never found out what caused the issue. I would really like to know though. I got the code while driving through some high temp, high elevations during the summer. The thinner air might of had something to do with it.

This problem is a pain. I changed my boost sensor trying to fix it, but it turned out I could have fixed it in 3 seconds by wiggling the connector on the atmosperic pressure, temp. sensor(The one in the intake). I've also heard of a few people having trouble with the same sensor going bad.

What codes were coming up? Did you do the three key cycles? I have a 0243 code that seems to be doing the same thing you describe. I have very low boost.



This is cut and pasted from my thread... ...





I have a juice with attitude with the hot program. My truck right now is a guttless wonder that will only hit about 15psi of boost. The 0243 code is a Turbocharger Wastegate Solenoid A malfunction. Now I think I have most of my problem solved... ... ... ... . This wastegate solenoid must be malfunctioning. Do I just replace the solenoid? Is it actualy connected to the wastegate that could be sticking? Smash something with a hammer? Dealership to clear a code?
