DDEC 4 Code 34 Turbo Boost Circ Low

[encantotom]

hi all,

just running my rig in the driveway i have started getting a check engine light with the error of Turbo Boost Circ Low on the prodriver. code 34.

the turbo boost sensor is part number 23522322 and is in plain site on the exhaust manifold on the passenger side of the engine right above the DDEC4 ECM.

i have found some troubleshooting for it online for a DDEC3, but i think the sensor is different on a DDEC3 than it is on my ddec4.

do any of you have the dde4 troubleshooting manual?

or have any experience with this error?

i am guessing it is a wiring or sensor issue and not a turbo issue from what i can read about it.

any wisdom?

a sensor is like 75 bucks so not expensive to try.

thanks

tom
